OSRS Sol Heredit Guide: 6 Phases and Colosseum Strategy

Sol Heredit Strategy in Short

Sol Heredit is the wave 12 boss of the Fortis Colosseum: 1,500 hitpoints, combat level 1,563, weak to slash and close to immune to ranged and magic. The strategy fits in four rules. Dodge his four spear and shield attacks by standing on the right tile, because Protect from Melee does nothing against them. Pray Protect from Melee on the exact tick of each triple-attack hit. When he grapples, click the armour slot he names. Move off any tile a light beam targets. Beating him guarantees Dizana's quiver.

Sol Heredit opens the duel by telling you what the test is. His first line before phase one says he is testing your footwork, and for phase one that is all he does. His primary attacks are area attacks dealing up to 45 typeless melee damage, and every one of them can be avoided completely by standing in the right place. The wiki says not to camp Protect from Melee against them: the prayer does not reduce that damage, and having it on at the start of his triple attack stops you blocking the first hit.

There are four attack patterns (two spear, two shield), each with a defined safe tile, and a rule that tells you which one is coming: if he uses two of the same type in a row, the second uses the other pattern, and mixing a spear and a shield resets him to the first. After every phase transition he always opens with a spear attack, and if his last attack was Spear 1 the next will be Spear 2.

What makes it hard is everything layered on top. Each phase transition drops six more permanent pools of molten sand into a nine-by-nine square centred on you, one of which always lands on your own tile, so the arena you are dancing in shrinks every time you make progress. Each phase adds another light beam, and a beam that targets your position gives you three ticks to move before it hits for 70 or more. From phase two there is a triple attack that has to be prayed tick-perfectly, and from phase three a grapple that shouts which armour slot you have to defend.

You arrive at all of this having already fought eleven waves. The Fortis Colosseum is a solo challenge, the wiki calls it the spiritual successor of the Inferno, and the modifiers you accepted on the way (how much prayer Blasphemy drains, how much health Frailty took, where Reentry left permanent molten sand) are still live when the gladiators barricade the centre of the arena and the duel starts.

Most people are here for that quiver. If it is all you want, a Dizana's Quiver service gets it onto your account without the practice runs.

Is Sol Heredit the Right Fight for You Yet?

The wiki sets expectations plainly: completions are possible with inexpensive gear, but you should not expect to complete it in your first few attempts, and you should be mentally prepared to fail a lot and learn from it.

You are ready for this fight if:

• You have a strong slashing melee weapon. Sol's ranged and magic defences are enormous (a Magic level of 300 with +750 magic and +825 ranged defence bonuses), so an abyssal tentacle or better is described as essential.
• You also have a ranged option for the waves. The wiki is blunt that not bringing one will make your first quiver much harder, and that dealing with south spawns from the north-west pillar is difficult without it.
• You can prayer flick under pressure. Pillar stacks are solved by offticking, and the triple attack has to be prayed on the exact tick each hit lands.
• You are willing to learn a fixed wave procedure and stick to it. The wiki's position is that learning wave solving, becoming comfortable with pillar-stack flicking and recovering quickly from mistakes all matter more than any gear optimisation.

Come back later if any of these are true:

• You are planning a melee-only first quiver. Even with a scythe of vitur the wiki calls this extremely difficult, because south spawns and north-west pillar stacks are close to impossible to solve without a ranged option.
• You have not obtained a bow of Faerdhinen setup. It is described as strongly recommended for a first quiver, and the fallback of a scorching bow with Masori is a step down from it.
• You intend to run a noxious halberd without Myopia. Its reach makes controlling the Sol fight significantly harder, because you have to path manually to stay at a distance you can dodge from.
• You are treating the modifiers as flavour. Frailty III takes a 99 Hitpoints account to 60, at which point the wiki notes a light beam is a guaranteed death and a missed triple attack combo can finish you outright.

Access Requirements

The only quest requirement is Children of the Sun, which opens Varlamore. There is no combat or Slayer level gate and no entry fee, but you only reach Sol by clearing waves 1 to 11 in the same run.

The boss requirements checklist lists the gates for every other boss by group.

Colosseum Strategy for the Eleven Waves Before Sol

Sol Heredit is fought on wave 12 of the Fortis Colosseum, on the cliffs east of Civitas illa Fortis. Before every wave, wave 1 included, Minimus offers three random modifiers; you must take one, and it stays active until the run ends. The wave 1 offer is always Relentless, Blasphemy and Frailty.

You reach him by surviving the waves before him, so his difficulty compounds everything you already spent. The Fortis Colosseum guide lists every wave's enemies and reinforcements.

There are twelve waves and Sol is the twelfth. Waves one to eleven are made of Fremennik warband members plus a rotating cast of serpent shamans, jaguar warriors, javelin colossi, manticores, shockwave colossi and minotaurs, with reinforcements arriving whenever a wave is not cleared within forty seconds. Realistically only waves one, two and four can be cleared before reinforcements spawn at all. The waves the wiki names as hardest are six, eight, ten and eleven, purely because of how many enemies are on the floor at once.

Follow the recommended procedure exactly. Start each wave on the marked start tile, praying Protect from Magic on waves one, four, seven, eight and eleven and Protect from Missiles on all the others. On the fifth game tick after the modifier menu disappears, click towards tile A or tile B on the north-west pillar. That timing is what stops enemies spawning in the western area. Look south as you move to see what spawned there and pray accordingly. Kill the Fremennik warband in the order melee, mage, ranger. Deal with south spawns. Deal with reinforcements. Solve the pillar stack. Return to the start tile before the next wave begins.

The north-west pillar is recommended for a first quiver for three reasons. It gives roughly a one-in-six chance of a double south spawn on waves eight, ten and eleven, where the south-west pillar gives nearly a two-in-three chance of a double north. It lets you safespot the melee reinforcements while handling south spawns on the west side. And clicking towards the pillar on the fifth tick prevents western spawns entirely.

Go back near the start tile as soon as the last enemy of a wave dies, because after wave one you cannot move while the modifier menu is open. Getting caught out of position when the next wave spawns is an easy way to throw a run.

Then comes wave twelve. Groups of gladiators barricade the centre of the arena, limiting you to the area within the four pillars, roughly sixteen tiles by fifteen, and Sol Heredit, who has been sitting above the north gate the whole time, comes down.

Recommended Stats and Gear at Three Budgets

These are the wiki's suggested minimums for a first completion, and there is no level gate. The wiki says higher stats help most with bad double-south spawns, where you are under pressure to kill at least one enemy before reinforcements arrive.

The Ranged and Magic rows are about two specific one-shots. The venator bow at 97 Ranged and the shadow at 99 Magic each kill one of the three Fremennik in a single hit at the start of every wave.

The one item you cannot skip on that table is a strong slashing melee weapon, and his defence numbers show why. Sol Heredit has a Magic level of 300 and defensive bonuses of +750 against magic and +825 against ranged, so magic and ranged setups that carried you through eleven waves become close to useless the moment the duel starts. An abyssal tentacle is described as the floor; a scythe of vitur is the ceiling.

The waves are the opposite. A twisted bow is the strongest ranged option for wave clearing and loses only to a scythe overall, while a Tumeken's shadow buys convenience by one-shotting the melee Fremennik but falls off against the other enemies and offers almost no defence. Meanwhile a melee-only setup is called extremely difficult for a first quiver even with a scythe, because you cannot solve south spawns and north-west pillar stacks without reach.

Special attack weapons earn their inventory slots for very specific jobs. A Saradomin godsword one-shots the ranged Fremennik with minimal switches and its special restores a large amount of health and prayer, which is how you stabilise a wave that has started badly. Dragon claws finish enemies before reinforcements arrive and are the standard way to end the Sol fight once he drops below 10 per cent. For a first quiver, dragon claws are easier to use than burning claws because the damage arrives in one burst.

Stat-reduction weapons work on Sol, but they are a poor pick on a first attempt. He is not immune to stat reduction, so a dragon warhammer or elder maul makes him easier to hit, but the wiki's judgement is that for a first quiver, claws or a similar burst weapon that ends the fight quickly below 10 per cent are much more valuable.

A noxious halberd is strong in the waves, but reaching Sol with one when you were never offered Myopia makes the fight significantly harder, because the halberd's reach keeps dragging you into range when you are trying to stand two tiles away. Many players carrying a halberd bring an abyssal tentacle purely for wave twelve.

• A 300 Magic level with +750 magic and +825 ranged defence is why your ranged and magic switches barely touch him. His slash defence is +5, so the slash weapon does the work.

Inventory and Supplies

The wiki gives full 28-slot inventories for five different setups and every one of them says the same thing about brews and restores: the quantity differs from person to person depending on how much you prayer flick. Count the restores you use per wave on practice runs and pack from that.

Inventory space runs out before money does. Every switch you bring for a one-shot is a supply you are not bringing, which is why the advice for a first quiver is to cut melee switches to a minimum until you can clear waves semi-consistently.

Prayer and Spellbook

First rule: do not camp Protect from Melee against Sol. His area attacks deal typeless melee damage that the prayer does not reduce, and having it active when his triple attack begins prevents you from blocking the first hit.

Protect from Melee is mandatory for the triple attack, and it has to be tick-perfect. The first hit lands three ticks after the charging animation starts, the second three ticks later, and the third after another three (four from phase four onwards). Activating any protection prayer too early disables it and you take the damage, so early is as bad as late. Unblocked, the three hits deal 15, 25 and 35 in phases two and three, rising to 15, 30 and 45 from phase four.

Offensive prayers are where your prayer points actually go. Rigour is what makes a venator bow with dragon arrows one-shot the seer, Piety is what makes a Saradomin godsword special one-shot the archer, and Augury is part of the requirement if you are freezing the warband with Ice Barrage. Flicking those through the waves saves a lot of super restores.

Blasphemy adds a drain on top. At its three tiers it drains 20, 40 or 60 per cent of the damage you take as prayer points, and the wiki's assessment is that it requires no conscious effort to handle and only kills players who habitually camp low prayer. At Sol it kills you indirectly: a light beam smites your prayer, and with no prayer you cannot block the triple attack.

Mechanics That Decide the Fight

Here is the pattern rule in full. If Sol uses two attacks of the same type in a row (two spears or two shields), the second one uses the other pattern. Using a spear then a shield, or a shield then a spear, resets him back to the first pattern of that type. He remembers his previous attack through a phase transition, but that memory resets if he used a special attack, either the grapple or the triple combo. And he always opens with a spear attack after a transition.

There are two ways to play that, and the wiki is clear about which is better. The hover method uses a lookup: after any special, hover one tile back at the sides or the middle; after Shield 1, two tiles back; after Shield 2, one tile back; after Spear 1, one tile back on the off-centre tiles; after Spear 2, one tile back at the sides or the middle. It lets you pre-empt every regular attack and gives you the most freedom to manoeuvre around molten sand. The L method (moving in an L shape from his corner) automatically dodges Spear 1, Spear 2 and Shield 2, and is always safe straight out of a phase transition, but forces you to react to Shield 1, which takes your attention away from beams and specials.

His attack speeds are tied to the attack he last used: spear stabs are seven ticks, shield slams six. Both speed up by one tick each after he drops below 75 per cent health and completes that phase transition.

Several modifiers carry into wave twelve. Reentry II or III means the permanent molten sand you left in the middle of the arena during the waves is still there for the duel, which can severely limit your dodging space. Quartet spawns a Fremennik warband member at the start of the fight, which you have to kill while dodging. It is a common death, because red-clicking it while switching weapons gets you hit. Bees keep spawning in a small arena. Solarflare orbs rotate in a fixed five-by-five pattern by the corners, with the areas inside and between the boxes safe. And Totemic starts spawning totems at 50 per cent that heal him 75 hitpoints every 4.2 seconds until destroyed. One manually cast spell removes one, and it takes two minutes to come back.

Where Sol Heredit Sits in Progression

Among the solo wave challenges, TzTok-Jad in the Fight Caves is the entry point. Sol Heredit sits at the top with triple Jads on Inferno wave 68 and TzKal-Zuk. He is the strongest monster in the game by combat level, but the fight leans on memorised positioning more than on Zuk-style shield tracking.

Phase by Phase

Phase 1: 100 per cent, 1,500 hitpoints

He opens with the line about testing your footwork, and with Spear 1. For this entire phase there is nothing to do except dodge: four area patterns, up to 45 typeless damage each, all of them avoidable by standing in the right place. No hazards, no specials, no beams.

Use it to establish the habit that carries the rest of the fight. Keep at least two tiles of room behind you, because while both spear patterns and the first shield slam can be dodged by moving one tile, the second shield slam needs two. And keep Protect from Melee off, because it does nothing against these attacks and will cost you the first hit of the triple attack later.

Phase 2: 90 per cent, 1,350 hitpoints

At the first transition, six tiles are marked with pillars of light and become permanent molten sand, one of them always on the tile you are standing on, and all of them inside a nine-by-nine square centred on you. Standing on molten sand costs roughly 6 to 8 damage per tick and adds Doom stacks if you took Doom.

The triple attack arrives here. It has to be prayed with Protect from Melee on the exact tick each hit lands, three ticks apart, and any protection prayer turned on too early is switched off and the damage goes through. Unblocked in this phase the three hits deal 15, 25 and 35.

So does the first light beam. A crystal spawns outside the arena, travels, stops and projects a beam, and a few seconds later fires a ball of light for 70 or more. If it targets your position you have three ticks to move.

Phase 3: 75 per cent, 1,125 hitpoints

Another light beam, another six molten sands, and his area attacks speed up by a tick: spear stabs to six, shield slams to five. That leaves one tick less between attacks to find the safe tile.

The grapple special also starts here. He announces one of five armour slots, above his model and in the chatbox, and you have to defend that slot. Body means your platebody, back means your cape, hands means gloves, legs means platelegs, feet means boots. Getting it right within three ticks blocks up to 45 damage; getting it right on the last possible tick gives you a perfect parry, which empowers your next attack within five ticks into a guaranteed max hit.

He will call a slot even when you have nothing equipped in it, and in that case you cannot defend it.

Phase 4: 50 per cent, 750 hitpoints

Another beam, another six pools of sand, and a timing change on the triple attack: the final hit is delayed by an extra tick, from three to four, so the rhythm you used in phases two and three is now wrong for the last hit. Unblocked, that final hit now deals 45 instead of 35, and the middle hit rises from 25 to 30.

By this point the arena has up to eighteen permanent sand tiles in it, all placed in nine-by-nine squares around wherever you were standing at each transition. Sand that lands on a tile already covered adds nothing, so the count can be lower. Where you stand at a transition is the only control you have over that, so pick the tile a few seconds before each one.

Phase 5: 25 per cent, 375 hitpoints

Mechanically identical to phase four, with one more light beam and one more set of six molten sands. This is the last beam he adds: four in total from here on.

Nothing new is added here. You are running the same phase four habits on a smaller floor with four beams.

Enrage: 10 per cent, 150 hitpoints

The enrage adds no new attacks, but the floor goes quickly. Five molten sand pools land immediately and then another arrives every three ticks on a random unaffected tile, still in a nine-by-nine square around you, so the arena is being consumed in real time. The light beams fire roughly every seven seconds and you now have only two ticks to react from the moment one targets you.

The wiki's priority order for this phase is unambiguous: dodging light beams comes above everything else, because a beam hit smites your prayer and without prayer you cannot block the triple attack. This is what dragon claws and burning claws are for: a burst that ends the fight before the floor runs out.

Do not relax on the kill. Doom stacks keep accruing after Sol dies and will still kill you at maximum stacks, and Volatility makes his corpse explode. If either finishes you off after the kill, you lose everything in the chest, including the quiver.

Fight Strategy, Step by Step

1. 1

   Before wave twelve starts, tag Sol with NPC highlights while he is still sitting above the north gate, turn up both game sounds and area sounds (his attack sounds are area sounds), and zoom out far enough to see the cue that appears above his head.

2. 2

   He opens with Spear 1.

   Step back one tile from his centre tile, or onto a corner tile.

3. 3

   Track his last attack to know the next pattern.

   Two of the same type in a row means the second uses the other pattern; a spear followed by a shield, or the reverse, resets him to the first pattern.

4. 4

   Keep two tiles of space behind you at all times, because Shield 2 is the only pattern that needs two.

5. 5

   Leave Protect from Melee off between triple attacks.

   It does not reduce his area damage and it will cost you the first hit of the combo.

6. 6

   When he charges the triple attack, pray Protect from Melee on the tick each hit lands:

   three ticks apart, and four for the final hit from phase four onwards.

7. 7

   Choose where you are standing at every phase transition.

   The six new molten sand pools spawn in a nine-by-nine square around you, and one of them will always be your tile.

8. 8

   Answer the grapple by slot: body, back, hands, legs, feet.

   If you can afford the risk, counter on the last tick for the perfect parry and the free max hit.

9. 9

   Move for every light beam that targets you.

   You get three ticks in the ordinary phases and two in enrage.

10. 10

    Below 10 per cent, dump your special attacks and finish it before the sand takes the arena.

Use his attack delay. Sol cannot move for four ticks starting from the tick he uses an area attack, and he has to be next to you at the start of a tick to begin one. Walking away before his cooldown finishes delays his next attack outright, which buys time to heal, reposition around sand, or reset your rhythm after a mistake. It works on everything except phase transitions, which he begins regardless of where you are.

Decide in advance which hazard wins when two arrive together. The wiki's ordering for the enrage phase works for the whole fight: the light beam is the highest priority, because it deals 70 or more and smites your prayer, and losing your prayer is what turns a survivable triple attack into a death. Take a sand tick, take an area attack, take the grapple, and still move for the beam.

Positioning and Movement

Wave 12 is fought in a smaller box. Gladiators barricade the centre when wave twelve begins, restricting you to the space within the four pillars, roughly sixteen tiles by fifteen.

Two tiles of clearance is the number to hold. Both spear patterns and Shield 1 can be dodged with a single step, but Shield 2 needs two, so a position that only offers one tile of retreat is a position where one of his four patterns kills you.

Pick your tile before each phase transition. Six pools of molten sand spawn in a nine-by-nine square centred on you and one always lands on your tile, so transitioning near an edge concentrates the damage into ground you were already avoiding. The wiki also notes that if you are at an edge or corner, all six will still spawn inside the arena where space allows.

If you took Reentry II or III during the waves, the molten sand you left in the centre of the arena is permanent and still there for the duel. Keep the middle clean during the waves so you are not fighting Sol in a room you already ruined.

Solarflare orbs, if active, circle a fixed five-by-five pattern by the corners. The areas inside the boxes and between them are safe, so once you know the paths you can stand clear of them.

Beginner Plan, Then the Advanced One

Your first trips

1. 1

   Get a bow of Faerdhinen setup before you seriously attempt this.

   The wiki calls it highly recommended for a first quiver and ranks the alternatives (a scorching bow with Masori, or a hunters' sunlight crossbow) below it.

2. 2

   Install the tile marker pack.

   It includes the wave start tiles for both pillars, the A and B tiles for offticking double south spawns, the deadzones you cannot walk into, the solarflare paths for the Sol fight, and the jaguar trap tiles.

3. 3

   Run the north-west pillar and follow the wave procedure exactly:

   start tile, correct prayer for the wave, click towards A or B on the fifth tick, kill the Fremennik in the order melee, mage, ranger, then south spawns, then reinforcements, then the pillar stack, then back to the start tile.

4. 4

   Stand still and take Fremennik damage instead of walking to avoid it.

   The wiki warns that learners internalise walking early, then keep doing it late in waves and die to mage-first reinforcements because their Fremennik were still alive at fourteen seconds.

5. 5

   Pick the boring modifiers early.

   Relentless, Blasphemy and Frailty are all rated as safe picks and taking manageable tier ones as soon as possible reduces the chance of being forced into something bad later. Bees, Red Flag and Totemic are the ones to refuse.

6. 6

   For the Sol fight itself, use the L method as a fallback and the hover method as the goal.

   The L shape from his corner dodges Spear 1, Spear 2 and Shield 2 automatically and is always safe out of a phase transition, so you only have to react to Shield 1.

7. 7

   Expect to fail.

   The wiki says not to expect a completion in your first few attempts, and to learn from each failure.

Once the kill is boring

• Learn the hover method properly. Knowing that Shield 1 means hovering two tiles back, Shield 2 and Spear 2 mean one tile back at the sides or middle, and Spear 1 means one tile back off-centre lets you pre-empt every regular attack, which is what frees your attention for the beams and specials.
• Use the attack delay. Walking away from Sol before his four-tick cooldown finishes pushes his next attack back, and it works on every attack except a phase transition. It is the closest thing the fight has to a pause button.
• Practise the perfect parry. Countering the grapple on the last possible tick gives you the perfect parry message and empowers your next attack within five game ticks with a max hit. That is a free max hit every grapple.
• Take Volatility at wave twelve if it is offered. Unless Quartet is active (the extra Fremennik explodes when it dies too), it only deals damage after Sol is already dead, which makes it one of the easiest picks at that point. It can still kill you at low health, and dying after the kill loses the chest.
• Learn the solarflare skip. At tiers one and two the flare moves every two ticks and only the second tick is damaging, so you can wait until its true tile overlaps yours and click away. At tier three it moves every tick, and clicking on its true tile as it moves puts you where it has already left.
• Use the venator bow's ricochets where triple bounces are available (mainly waves one to six and ten to eleven), where it beats even a scythe with Masori equipped. Leave that until after your first quiver.

Drops and What Sol Heredit Is Worth

The reward most people come for is Dizana's quiver, given for every completion. Sol Heredit is the last obstacle in front of it, and nobody farms him for drops.

You can still lose it after winning. Doom stacks continue accruing after Sol dies and will still kill you if they reach maximum, and Volatility makes his corpse explode. If either finishes you off after the kill, you lose all the loot in the chest, quiver included.

No values, completion rates or timings are printed here, because the rewards and their prices move. Check the live tables on the wiki.

Sunfire fanatic armour, echo crystals and tonalztics of ralos come from the wave chest, which fills as you clear waves. Every completion adds a quiver, and Minimus will trade a spare one for 4,000 sunfire splinters or a 1/200 roll at the Smol Heredit pet.

Combat Achievements

Two of the Colosseum's Combat Achievements go against the modifier advice on this page. One-off and Reinforcements both require you to pick modifiers the wiki tells first-quiver players to avoid, so leave them until you have completions in the bank.

The Sol-specific tasks: Sportsmanship (master) is one kill. I Brought Mine Too (master) means killing him using only a spear, hasta or halberd. Showboating (master) asks for the Fortis Salute to all four sides of the arena while he is below 10 per cent. Perfect Footwork (grandmaster) means no damage from his spear, shield, grapple or triple attack, Slow Dancing in the Sand (grandmaster) bans running for the whole fight, and Colosseum Grand Champion (grandmaster) is 10 kills.

Task lists move with updates, so check the current list in game.

Combat Achievements guide

Ironman Notes

Dizana's quiver is untradeable, so ironmen and mains earn it the same way. The difference is supplies: brews, restores and sanfews all have to come from your own Herblore and Farming.

The budget setup suits self-sufficient accounts. The wiki names the trident of the swamp as the most affordable magic switch and the easiest for Ironmen to get, and it does the same job as a sanguinesti staff for two-shotting the melee Fremennik.

If you own a sanguinesti staff and cannot spare the slots, the budget notes suggest uncharging it for blood runes and bringing a book of the dead in your offhand, which covers both thralls and Death Charge.

Do not skip the bow. Everything else on the budget list is flexible, but the wiki's judgement is that a bow of Faerdhinen setup is what makes a first quiver realistic, and the alternatives rank below it.

Common Mistakes and Death Causes

The stabilising tool in the waves is a Saradomin godsword special attack. It one-shots the ranged Fremennik and restores a large amount of health and prayer at the same time, which is exactly what you need after a rough wave start. The only exception to the melee, mage, ranger kill order is killing the ranger first with it when you are critically low.

In the Sol fight, you recover by moving. Walking away from him before his four-tick cooldown finishes delays his next attack, which buys you the ticks to brew, restore prayer or move out of sand. A player who knows that rule can survive a botched triple attack; a player who does not has to eat the next area attack while healing.
