Akkha OSRS Guide: Memory Blast, Shadows and Style Swaps

Overview

Akkha is the boss at the end of the Path of Het in Tombs of Amascut. He attacks with melee, ranged and magic, and always prays against the style he is currently using, so you protect against his style and hit him with one of your other two. At 80%, 60%, 40% and 20% HP he turns immune and four shadows appear in the corners; kill one and pull him into its quadrant to damage him again.

On top of that he has three special attacks. Memory Blast lights the four floor quadrants in a sequence you have to follow, Trailing Orbs drops orbs behind you as you walk, and Detonate (group only) punishes players sharing a row or column. When his HP hits zero he restores 20% and makes a final stand you can only melee.

Requirements and Access

Akkha has no requirement of his own beyond raid access. The real variable is which invocations your team has turned on.

If you have not run Tombs of Amascut before, read the Tombs of Amascut guide first. Invocation choice affects Akkha more than your gear does.

Getting There

Akkha sits at the end of the Path of Het inside Tombs of Amascut.

1. Complete Beneath Cursed Sands and travel to the Necropolis (fairy ring AKP is one of the quickest routes).
2. Set your invocations, then enter the raid and choose the Path of Het.
3. Clear the mirror puzzle: reflect the caster statue's beam onto the shielded statue, then mine Het's Seal during the 15-tick window before it shields again.

The wiki's suggested learning order puts Akkha third, after Zebak and Kephri, and many players rate him the hardest path boss to solo. Learn him once you are comfortable switching styles under pressure.

Recommended Stats

Akkha scales with raid level rather than being a fixed stat check. These are levels where the fight is comfortable at moderate invocations.

Gear Setups: Budget, Mid and Best in Slot

Akkha is a switching fight. You want your two best styles rather than one very strong style, because he only protects against one style at a time and that style changes during the kill.

Akkha's shadows have only 30 Defence and a 60% weakness to wind spells, so a blowpipe or Tumeken's shadow deletes them quickly. The lightbearer pulls its weight across the whole raid, since special attacks get used in every room.

Inventory and Supplies

Raid inventories are a shared budget across every room, so what you bring to Akkha has to survive the rest of the raid too.

• Saradomin brews and super restores as your sustain.
• Your style switches: at minimum a ranged and a magic option.
• Ranging and magic potions, or divine variants.
• A melee weapon for the final stand, where he prays magic and ranged at once.
• Run energy matters here. Smelling salts from the Helpful Spirit restore 25% run energy every 15 seconds for 8 minutes, on top of the combat boost.

Your HP, prayer, run energy and special attack refill after every path boss, but consumables do not. If Akkha comes early in your order, you still have two more paths and the Wardens ahead of you.

Mechanics You Have to Respect

Akkha runs a style rotation that dictates both his prayer and yours, a shadow phase every 20% of his health, and a special attack every seventh attack. Your protection prayers only block part of his damage: about 80-90% of his ranged and magic and about 75% of his melee.

Attack counts and special timings were last changed in June 2025, so verify current behaviour on the OSRS Wiki Akkha page.

Phase-by-Phase Strategy

Akkha is best learned in two passes: first learn to survive the style rotation, then learn to do the shadows and Memory Blast quickly.

1. Enter with your best non-melee weapon ready. He starts in melee, so Protect from Melee first.
2. Keep him in melee as long as you can by staying out of his reach between your attacks. Advanced players run circles in a quadrant (the butterfly method), because he cannot hit diagonally.
3. When he switches to ranged, pray Protect from Missiles and attack with magic or melee. When he switches to magic, pray Protect from Magic and attack with ranged or melee.
4. At 80% HP, kill one shadow, stand in its quadrant, and get him back on you there. Repeat at 60%, 40% and 20%; each threshold fully restores any damaged shadows.
5. On Memory Blast, stand still and watch the full sequence before moving. Walk to each quadrant as it comes up.
6. On Trailing Orbs, stop moving until the message says they have stopped, or move only onto fresh tiles.
7. When he restores 20% for the final stand, switch to melee, ignore Protect from Magic at raid level 300+ when solo, and path around the white orbs to reach him.

Learners should run low invocations for their first several Akkha kills. The mechanics are identical at low raid level, just survivable.

Solo Versus Team

Akkha scales with raid size. In a team, one player tanks by standing closest to him after each special, since he targets the nearest player and breaks ties by highest defence bonus. The rest spread out for Detonate and work on shadows.

Solo Akkha is entirely reasonable at low invocations. Detonate never happens solo, which leaves Memory Blast and Trailing Orbs as the specials to learn.

The rest of the raid's rooms and bosses are covered in the Tombs of Amascut guide, and the other path bosses each have their own guide.

Common Mistakes and What Actually Kills You

Akkha deaths are almost always a switching failure or an invocation choice made for reward rather than survival.

• Attacking with the style he is currently praying against, so your damage drops to zero after a switch.
• Moving before the Memory Blast sequence has finished showing.
• Splitting damage across several shadows, so none of them die before their quadrant attack charges.
• Walking back over your own trail during Trailing Orbs.
• Bringing only ranged and magic, then having no way to damage him in the final stand.
• Running high invocations while still learning the style rotation.
• Spending all supplies at Akkha and arriving at the Wardens empty.

Drops Worth Knowing

Akkha has no loot table of his own. He always drops Het's capture (if it is not in your bank), and the top damage dealer gets eldritch ashes, one of the four boss items used for the ancient key after the Into the Tombs miniquest. The real reward is the points he feeds into the raid's unique roll.

Combat Achievements and Perfect Akkha

Perfect Akkha is a Master tier task. You need a group of two or more, every Akkha invocation enabled, and a normal-mode raid (raid level 150+). Nobody may take damage from his attacks off-prayer, his specials (orbs, Memory Blast, Detonate), shadow timers or final-stand orbs, and nobody may attack him with the style he is protecting against.

The wiki notes that a melee thrall in the final stand fails the task, so leave thralls off. With Double Trouble on, he can use two specials at once; one player handles Memory Blast in the middle while the others use the staircase method along the edges.

The four Akkha invocations are Double Trouble (two specials at once), Keep Back (ranged and magic attacks also hit adjacent players with melee), Stay Vigilant (a special every 6 attacks instead of 7, and his style and prayer swaps come at random instead of on a fixed count) and Feeling Special? (two ticks between Memory Blast steps and an extra orb in front of you).

Ironman Notes

Masori armour and Osmumten's fang only come from ToA, so an iron has to raid for them. Akkha is where you find out whether your magic and ranged setups are good enough for the raid.

ToA is supply-hungry, so brews and restores are the real constraint. Build a Herblore and Farming base before treating ToA as a grind rather than an occasional run.

Masori and Osmumten's fang are major upgrades an iron can only earn here, which makes low-invocation solo runs a good use of time.

FAQ

How does Akkha's prayer work?

He prays against the same style he is attacking with. In melee form he has Protect from Melee up, so you pray melee and hit him with ranged or magic. When he switches to ranged or magic, his prayer switches with him.

How does Memory Blast work?

Akkha disappears and the four quadrant markers light up one at a time. Stand in each lit quadrant in that order; you get four ticks to move between bursts, and the next quadrant is always adjacent to the last.

When do Akkha's shadows spawn?

At 80% HP, then the shadows are restored at 60%, 40% and 20%. He is immune until you kill a shadow and bring him into that quadrant.

Is Akkha a good first ToA boss?

Usually not. The common learning order is Zebak, Kephri, Akkha, Ba-Ba, and Akkha is often called the hardest path boss to solo. Learn him once style switching feels automatic.

What is the best weapon for Akkha?

Tumeken's shadow, by a long way. Below that, pair a blowpipe or Bow of Faerdhinen with a powered staff, and bring a melee weapon such as Osmumten's fang for the final stand.

What is Perfect Akkha?

A Master Combat Achievement: kill Akkha in a group of two or more with every Akkha invocation on, without anyone taking avoidable damage or attacking into his prayer.

Does Akkha drop anything himself?

Only Het's capture and, for the top damage dealer, eldritch ashes. Uniques come from the raid chest at the end.

Bottom Line

Akkha is a prayer check stacked on a memory test. Pray his style, hit him with another, work one shadow at a time, and follow the Memory Blast lights in order.

Learn him at low invocations, where every mechanic is present but survivable, and raise raid level only once your switches are automatic.
