OSRS Nightmare Guide: Group Gear, Tanking and Drop Rates

Why People Fight The Nightmare

The Nightmare is a combat level 814 group boss in the Sisterhood Sanctuary beneath Slepe, and the only requirement is Morytania access through Priest in Peril. Any team from one player up to 80 can fight her, but she never scales below a five-man, and each kill rolls for inquisitor's armour, the inquisitor's mace, the nightmare staff and three orbs. This page covers the group fight; the solo-only version has its own Phosani's Nightmare guide.

The Nightmare is the only major group boss in the game where hitting the boss is not how you kill the boss. Her physical health is 2,400 and you never touch it with a weapon. Instead each phase gives you a shield to break, and once it shatters your attacks on her stop doing anything at all — you leave her alone and go and charge the four totems in the corners of the room. When all four are full they fire a magical blast into her for 800 damage. Three of those, and the fight is over.

That structure is why team size changes this encounter more than it changes almost any other. The shield has a minimum durability of 2,000 per phase and a cap of 19,600, and it grows by 200 from the base for every player in a six-man or larger group. The totems have a minimum charge requirement of 300, capping at 2,640, growing by 30 per player on the same terms. And by default she scales her shield and totem charge to a five-man encounter, so everything below five players is fighting a five-man shield with fewer people. A solo kill generally takes well over sixteen minutes for exactly that reason, which is why solos are usually done for Combat Achievements or as practice for Phosani's rather than for value.

Her targeting is the other thing that separates her from her neighbours. She looks at each player's highest Defence roll across all five attack types and focuses whoever has the highest overall value, which makes a designated tank something you can create simply by wearing more defensive gear than everybody else. Full justiciar is targeted over oathplate. That inverts the usual advice about optimising, and it means the tank's job is a gear decision made before the fight rather than a positioning one made during it.

The rest is three phases that share one special attack and nothing else. Grasping Claws appears in all three. Phase one adds husks and corpse flowers, phase two adds the curse and the parasites, phase three adds spores and the surge. Learning her is really learning which three attacks are possible right now, because the ones that are not possible are the ones you can stop watching for.

Its own attacks are melee (slash), ranged and magic, so Protect from Melee, Missiles and Magic all have a job.

Is The Nightmare the Right Fight for You Yet?

The Nightmare has almost no access requirements (Priest in Peril for Morytania, and that is it), which makes her unusually easy to walk into and unusually easy to be underprepared for. What actually gates her is whether you can hold three-tick prayer reactions while doing something else, and whether you have a team that will turn up more than once.

You are ready for this fight if:

• You can react to an attack in three ticks. That is the window on her ranged and magic attacks, and her melee gives you two.
• You have people. She scales her shield to a five-man encounter no matter how few of you show up, so a duo is doing a five-man's work with two sets of hands.
• You are carrying Sanfew serums or Relicym's balm. A dose taken before a parasite bursts halves the problem: a weakened parasite has 40 hitpoints instead of 80 and does far less damage on the way out.
• Somebody has agreed to be the tank and has the gear to actually win the targeting check.

Come back later if any of these are true:

• You are planning to solo her for profit. Each solo kill generally runs well over sixteen minutes because the shield does not scale down below five players, and the wiki treats solos as Combat Achievement or Phosani's practice rather than a method.
• Your magic gear is your upgrade priority. The wiki is explicit that melee upgrades should come before magic ones here, and that you should only bring a magic switch if the rest of the group is doing the same.
• You are counting on a salve amulet. She is not undead, so it does nothing.
• Nobody in your duo knows the failure condition. If one player dies in a small team, the survivor has to keep up enough damage or be teleported out with the message that the Nightmare grows tired of your poor efforts.

Access Requirements

Morytania access is the only requirement, which means finishing Priest in Peril. There is no Slayer level, no Combat level gate and no kill count. Sins of the Father is not needed. A Taste of Hope is worth doing for Drakan's medallion, the fastest travel, but it is optional.

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

Location and How to Get There

She is in the Sisterhood Sanctuary, the dungeon beneath Slepe in Morytania, and the only hard requirement to be there is Priest in Peril for Morytania access. The travel is worth optimising because you will be doing it repeatedly.

The five quickest routes to Slepe, fastest first: Drakan's medallion teleported directly to Slepe, which is unlocked with a Slepey tablet from Phosani's Nightmare; the Spider cave teleport, which lands you north-west of Slepe; the Hallowed Sepulchre teleport with a hallowed crystal shard, then east via an agility shortcut needing 63 Agility and two long ropes installed; Drakan's medallion to Ver Sinhaza, then north past the small dock and east; and the ectophial to the Ectofuntus, then north to the dock to pay Andras 10,000 coins to row you to Slepe, arriving at a dock south-west of the town.

A Taste of Hope is the quest worth having for this, since it gives you Drakan's medallion. If you do not have it, Ghosts Ahoy and the ectophial is the second-quickest option.

Starting the fight means disturbing her while she is sleeping. If somebody else is already in there she will be floating, with a symbol on the ground beneath her showing which of the three phases the current fight is in — and her instance cannot be joined mid-fight, so your options are to wait it out or hop worlds.

Recommended Stats and Gear at Three Budgets

These are the wiki's advised levels rather than gates. Nothing stops a lower-levelled account walking in. What lower stats actually cost you here is time, and time at the Nightmare is measured in special attacks survived rather than in minutes.

The Magic row is the one people skip and should not. Totems have no stats at all, so magic accuracy is irrelevant, but they take double damage from magic, which makes your magic switch the difference between a brisk totem phase and a long one spent still eating her phase attacks.

The most important thing about the totem switch is that it is a damage switch and not an accuracy one. Totems have no stats whatsoever, so magic accuracy does nothing for you. Only magic damage bonus has any effect, and totems take double damage when struck with magic. That is also why the ghost thrall is the best thrall here: it deals magic damage, so it inherits the doubling.

The tank's gear advice runs backwards from everywhere else in the game, and it is worth reading twice. She targets whoever has the highest Defence roll across all five attack types, so if you want to be the tank you deliberately wear more defensive and less offensive gear — guardian boots instead of Avernic treads, Torva instead of Inquisitor's, Barrows gloves instead of Ferocious. If you do not want to be the tank, do not accidentally win that contest.

She is not undead, so a salve amulet does nothing at all. That trips up players coming from the rest of Morytania, where it is usually the correct answer.

Defence reduction works with an expiry date. She is susceptible to a dragon warhammer special, but she restores her Defence at 20 points per minute, which is why the recommendation is one defence-reducing special per phase rather than a stack at the start. The crimson kisten's special is best used after her defence has already been reduced.

Two upgrade-order notes. Melee gear should be prioritised over magic gear, because melee is what breaks the shield and the shield is the timer. And you should only bring a magic armour switch if everybody else in the group is bringing one too — a lone player switching for the totem phase while nobody else does is spending inventory space for a fraction of the benefit.

An amulet of blood fury is worth carrying while you are learning, for the passive healing on a long kill, with the honest caveat that it raises your supply cost per kill and slightly lowers your damage.

Inventory and Supplies

The wiki gives full inventories for melee, totem and solo setups, and the solo one is instructive: it drops the Ancestral robes for extra Saradomin brews, on the reasoning that kills are long and you want room for mistakes rather than marginal totem damage. That trade — supplies over optimisation — is the right one whenever you are still learning.

If you are running kills back to back with an alt account, you can trade supplies or cast Energy Transfer between kills, which is how longer trips are actually achieved.

Prayer and Spellbook

Her three standard attacks come with different reaction windows, and knowing which is which is most of the prayer work. The ranged attack has her contorting and firing projectiles, with a loud clicking sound per contortion, and you have three ticks to get Protect from Missiles up. The magic attack has her flailing sideways in a cloud of pink petals before spinning back to fire them, again with three ticks to react with Protect from Magic. The melee attack is a claw charge and slash, and it gives you only two.

Praying wrongly is worse than not praying at all in at least one case. Her melee damage is multiplied by 6/5, or 120 per cent of her maximum hit, when you have the wrong protection prayer up, which is a deliberate design choice rather than a quirk. The same may apply to her magic and ranged attacks, though that has not been confirmed.

Her melee has an escape that her other attacks do not. It damages everyone in front of her, including diagonally, as well as anyone underneath — and it always hits regardless of your defensive bonuses. But it only reaches the direction she is facing, so standing anywhere else, or walking one tile away if she is looking at you, avoids it entirely. Everybody who is not the tank should be spending the fight out of her arc.

The curse in phase two is the prayer mechanic that catches experienced players. Your screen fills with a pink glow and your protection prayers are shuffled: clicking Protect from Magic gives you Protect from Missiles, clicking Missiles gives you Melee, and clicking Melee gives you Magic. It lasts five attacks. The answer is to click one step back around the cycle rather than to panic, and to count the five.

Keep Piety on throughout, and flick it if you can. Flicking offensive prayers on a fight this long is a large enough saving to change how many brews you can afford to bring.

Mechanics That Decide the Fight

Every mechanic in the fight scales with the number of players in the instance when it starts, and the numbers are worth committing to memory because they explain why small teams feel so different. The shield has a minimum durability of 2,000 per phase and a cap of 19,600, rising by 200 from the base per player in a six-man or larger group. The totems have a minimum charge requirement of 300, capping at 2,640, rising by 30 per player on the same terms. The number of sleepwalkers grows with headcount, from one to 24. And she scales her shield and totem charge to a five-man by default, so any team smaller than five is doing a five-man's work.

There is one timing interaction in phase one that costs teams whole kills, and it is not obvious. If she casts husks at the same moment your totems finish charging, players can be frozen while the phase-two sleepwalkers spawn — and frozen players cannot kill sleepwalkers with a melee weapon. The advice is to be cautious about fully charging the totems if she has not recently used husks, and for frozen players to switch to their magic weapon to help clear sleepwalkers.

Two smaller interactions worth knowing. Players immobilised by husks usually do not get a Grasping Claws portal underneath them, and she does not appear to use Corpse Flowers while players are immobilised. And during Corpse Flowers you need to know where the tank is: anyone who ends up on the same side of her as the tank can be caught by her melee afterwards.

Where The Nightmare Sits in Progression

Within the standalone boss group, the fights below The Nightmare are Dagannoth Supreme and The Royal Titans (Branda & Eldric). Above it sit Phosani's Nightmare and Yama.

Phase by Phase

Phase one: husks and corpse flowers

Her opening phase gives you Grasping Claws, husks and corpse flowers, and the job is to break the shield while dealing with all three. Corpse flowers is the one that punishes carelessness the hardest: the wrong quadrant attacks you for up to 20 every tick, heals her for double what it deals, and any attack you make from the wrong quadrant heals her as well. Standing in a quadrant with berries on both sides doubles the incoming damage again.

When the shield goes down, stop hitting her. Your attacks do nothing from that point, and the four totems become vulnerable instead. She keeps using her phase-one attacks throughout the totem phase, so this is not a break.

Before you finish the last totem, check whether she has used husks recently. If she casts them just as the totems complete, one or more players will be frozen when the phase-two sleepwalkers spawn, and a frozen player who cannot reach the sleepwalkers means a much bigger power blast for the whole team. If you are the one frozen, switch to your magic weapon and kill what you can reach.

Phase two: the curse and the parasites

The phase opens with sleepwalkers, which is also the best moment in the fight to use a Saradomin godsword special: it always maximum hits on them, restoring health and prayer at the point you most want both.

Then it becomes the awkward phase. The curse shuffles your protection prayers for five attacks (Magic gives Missiles, Missiles gives Melee, Melee gives Magic) while parasites are being thrown at random players. Your Hitpoints icon turns pink when you have one, and you have about 18 ticks before it bursts out for heavy damage. Drinking a Sanfew serum or Relicym's balm in that window weakens it to 40 hitpoints instead of 80 and cuts the damage substantially.

Killing the parasite afterwards is not optional. Left alive it restores her shield by 31 to 50 units at a time, and does the same for the totems if the totem phase has already begun. Only if there is nothing for it to heal does it turn on you, alternating ranged and magic attacks until something takes damage.

• On solo kills, walk underneath her just before the parasite bursts, roughly five bludgeon or mace attacks, or four scythe attacks, after the parasite lands. A parasite that spawns under her cannot heal her until it moves.
• The scythe is poor against parasites and husks. A crimson kisten or an inquisitor's mace clears them far faster.
• Solo players will often face several parasite specials back to back, which is the single biggest reason solo kills run long.

Phase three: spores and the surge

Another sleepwalker opening, handled the same way (Saradomin godsword special or blood barrage, depending on team size), and then the last set of specials: Grasping Claws, spores and the surge.

Spores are scattered in set patterns and are more dangerous than they look, because they appear as one tile but carry a three-by-three area. Triggering one disables your run and slows your attack speed by a tick, and the effect can spread to other players. The reason that matters is that she frequently uses Grasping Claws while spores are still active, so the tile you need to step to in order to dodge a portal may be a tile that will cripple you.

The surge is the cleanest attack she has. She teleports to one of the four edges of the room and charges straight across to the opposite side, dealing up to 60 to anyone in the way. Get out of the lane.

Break the shield, charge the four totems one last time, and the third 800-damage blast finishes her.

Fight Strategy: Team size vs unique rates

1. 1

   Pre-pot with an anglerfish and a sip of stamina before you leave the bank, then run in and disturb her while she is sleeping.

2. 2

   Confirm the tank before the first attack.

   She targets whoever has the highest Defence roll across all five attack types, so this is decided by gear rather than by who clicks first.

3. 3

   Everybody who is not the tank stays out of the direction she is facing.

   Her melee hits everyone in front of her, diagonals included, and always lands regardless of defensive bonuses.

4. 4

   Break the phase-one shield while handling Grasping Claws, husks and corpse flowers.

   Get to the quadrant with flowers on both sides, and stop attacking from a berry quadrant, because it heals her.

5. 5

   When the shield shatters, stop hitting her and go to a totem.

   Switch to magic if you brought it; totems take double damage from magic and have no stats for accuracy to matter against.

6. 6

   Before completing the last totem, check whether husks have recently been used.

   Finishing into a fresh husk cast means frozen players during the sleepwalker spawn.

7. 7

   Open phase two on the sleepwalkers with a Saradomin godsword special for the health and prayer restore, then handle the curse by clicking one step back around the prayer cycle.

8. 8

   Drink a Sanfew serum or Relicym's balm the moment your Hitpoints icon turns pink, then kill the parasite before it starts topping her shield back up.

9. 9

   Open phase three the same way, then route around spores, step out of the surge lane, and finish the last set of totems.

The rhythm of a good Nightmare kill is unusual because there are two entirely different jobs and they alternate. The shield phase is a melee damage race with prayer switching on top; the totem phase is a magic damage race with the same prayer switching and none of the target you have been hitting for the last few minutes. Teams that treat those as one continuous fight tend to keep hitting her for a few seconds after the shield breaks, which is pure lost time.

The other thing worth building as a habit is dealing with her healing sources before her health. A parasite left alive restores her shield by 31 to 50 at a time. Attacking from the wrong corpse-flower quadrant heals her. Berry damage heals her for double. She has more ways to undo your progress than to kill you, and a team that removes those first usually finds the damage race was never the problem.

Positioning and Movement

The most important positional rule has nothing to do with the special attacks. Only the tank should be standing in the direction she is facing, because her melee hits everyone in front of her — diagonals included — and under her, and it always lands regardless of your defensive bonuses. Everybody else fights from her flanks or behind her.

During corpse flowers, that rule interacts with the quadrant you have to move to. Players who end up on the same side of her as the tank can be caught by her melee immediately afterwards, so getting to the safe quadrant is only half the problem — you also need to know which part of it you can stand in.

For sleepwalkers, teams commonly assign players to specific sections of the arena. It is a simple habit that turns an unavoidable, scaling power blast into a predictable, small one, and in larger teams putting blood barrage on one or two players clears several at once.

In phase three, plan your Grasping Claws dodge before the portals appear. Spores have a three-by-three area despite their one-tile appearance, and she routinely uses claws while spores are still on the floor — the players who get caught are the ones working out both problems at the same moment.

Beginner Plan, Then the Advanced One

Your first trips

1. 1

   Learn her in a five-man before you try anything smaller.

   Below five players she still uses five-man shield and totem values, so a duo or a trio is a harder version of the same fight rather than an easier one.

2. 2

   Bring an amulet of blood fury for your learning kills.

   The passive healing on a long fight covers a lot of small mistakes, with the caveat that it costs upkeep and slightly lowers your damage.

3. 3

   Get the parasite habit early: the instant your Hitpoints icon turns pink, drink.

   You can click the Hitpoints orb rather than finding the potion in your inventory, which is faster under pressure.

4. 4

   Memorise the curse cycle before you meet it rather than during it.

   Magic gives Missiles, Missiles gives Melee, Melee gives Magic, and it lifts after five attacks.

5. 5

   Stay out of her facing arc unless you are the tank, and check that you are not accidentally winning the targeting contest with your own defensive gear.

6. 6

   Bring a magic switch, but only if the rest of the group is bringing one.

   Totems take double damage from magic and have no stats for accuracy to matter against, so it is a damage switch and nothing else.

Once the kill is boring

• Spend one defence-reducing special per phase rather than stacking them. She restores 20 Defence per minute, so anything beyond that is drained value, and the crimson kisten's special is best saved until after her Defence is already down.
• Use ghost thralls specifically. They deal magic damage, so they inherit the doubling on the totems, which no other thrall does.
• Time the last totem around her husk casts. Completing the totems into a fresh husk means frozen players during the sleepwalker spawn and a much larger power blast, and it is entirely preventable by waiting a few seconds.
• On solos, walk under her just before a parasite bursts, roughly five bludgeon or mace attacks, or four scythe attacks, after it lands. A parasite that spawns underneath her cannot heal her until it moves.
• Flick Piety rather than camping it. On a fight measured in phases rather than minutes, that is the difference between a comfortable prayer bill and bringing brews you would rather have spent on food.
• If you are running kills back to back, an alt account lets you trade supplies or cast Energy Transfer between them, which extends trips considerably.

Team Roles

Team size is the single biggest variable in this fight and the numbers are published, so there is no guesswork involved. The shield has a floor of 2,000 durability per phase and a ceiling of 19,600, gaining 200 from the base for every player in a six-man or larger encounter. Totems have a floor of 300 charge and a ceiling of 2,640, gaining 30 per player on the same basis. Sleepwalker counts scale from one to 24. And crucially, she defaults to five-man values, so anything below five players fights a five-man shield.

That default is why solos are a different activity rather than a harder version of the same one. Solo kills generally take well over sixteen minutes, and the wiki's framing is that players solo her for Combat Achievements or as practice for Phosani's Nightmare rather than for output. If you do solo her, an amulet of blood fury or a sanguinesti staff is effectively required to cover the chip damage across a kill that long.

Small teams have their own failure condition. In a duo, if one player dies, the survivor has to deal enough damage on their own or the instance ejects them with the message that the Nightmare grows tired of your poor efforts. Losing a player in a two-man is often the end of the kill rather than a setback.

Drops and What The Nightmare Is Worth

The Nightmare's own strategy page documents the fight rather than the loot, and one drop it does mention is worth knowing because it changes your travel: the Slepey tablet, which unlocks the Slepe teleport on Drakan's medallion and is a Phosani's Nightmare drop rather than one from the group version. That is the fastest route back for anyone doing this repeatedly.

Every kill rolls two unique tables: armour, mace and staff at 1/83.33, and the orbs at 1/320. Both can hit on the same kill. With more than five players there is also a (team size minus 5)% chance that both tables roll a second time, capped at 75% for 80 players, which is why the rates below get better in a mass.

Those are per-kill rates for the whole team, not per player. When a unique hits, a weighting based on damage dealt picks who gets it, and you only qualify for any drop if you damaged both the shield and the totems. The top damage dealer also gets big bones and 10% more of the regular loot. That is the real trade-off with team size: a mass rolls more uniques per kill, a small team gets a bigger share of each one.

The little nightmare pet works differently because tertiary drops can go to several players on the same kill. Its rate depends on the team size when the fight starts: 1/800 solo, 1/1,600 in a duo, 1/2,400 in a trio, 1/3,200 with four and 1/4,000 with five or more.

Combat Achievements

The Nightmare has Combat Achievement tasks, and a 60 max hit is the number to plan them around: any task that restricts your supplies or your gear is a materially different fight at that damage.

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

Combat Achievements guide

Ironman Notes

Without a Grand Exchange, inquisitor's armour, nightmare staff, harmonised orb has to be earned rather than bought, and this is the fastest table it sits on.

Two of the supplies this fight depends on are things a self-sufficient account can simply make. Sanfew serums and Relicym's balm both weaken parasites, and having a stack of either turns the phase-two problem from heavy damage into a manageable one.

The alt-account routine the wiki suggests (trading supplies or casting Energy Transfer between kills to extend trips) is not available to you, which makes trip length a real constraint. Plan around fewer, longer kills rather than a chain of them, and lean on flicking Piety to stretch the prayer supply.

An amulet of blood fury is the recommended learning item and the one hardest to justify on an Ironman because of the upkeep. A sanguinesti staff covers a similar role on the totem phase, where its healing benefits from magic damage being doubled against totems.

Common Mistakes and Death Causes

The reliable stabiliser is the sleepwalker phase. A Saradomin godsword special always maximum hits on sleepwalkers, restoring a large amount of health and prayer at the exact moment a phase transition would otherwise be pure incoming damage. If your team is running rough, that is the moment to fix it.

If a teammate goes down, the fight does not end but the maths changes: the shield and totem values were set when the instance started and do not shrink to match your reduced team, so the phase you are in will take longer with fewer people and more special attacks to survive. In a duo it can end the attempt outright, since a lone survivor who cannot maintain damage is teleported out.
