OSRS Soulreaper Axe: How to Make It, Stats & Where It's BiS

Soulreaper Axe: The Short Answer

The soulreaper axe is a two-handed slash axe that needs 80 Attack and 80 Strength to wield. You make it by combining four untradeable drops from the Desert Treasure II bosses (Leviathan's lure, siren's staff, executioner's axe head and eye of the Duke) with 2,000 blood runes, which takes 75 Magic that cannot be boosted. The finished axe is tradeable, so a main can also buy it on the Grand Exchange.

Its gimmick is soul stacks. Every attack adds one, up to five, and each stack raises your Strength level by 6%. With five stacks running it out-damages a blade of Saeldor or an Inquisitor's mace, and against 1x1 and 2x2 monsters it can beat a scythe of vitur.

The Four Pieces and Their Drop Rates

Add the four average rates together and you get 3,088 kills, with Vardorvis's axe head the slowest piece by a distance. Awakened kills roll each boss's unique table three times as often, but every attempt costs an awakener's orb, so they are not a practical way to farm pieces.

Each piece sits on the same unique table as that boss's vestige and chromium ingots. A long axe grind therefore also feeds the ancient rings: the magus ring from Duke, venator from the Leviathan, bellator from the Whisperer and ultor from Vardorvis, each needing its vestige plus three chromium ingots.

How to Make the Soulreaper Axe

1. 1

   Finish Desert Treasure II - The Fallen Empire so the post-quest versions of the four bosses are open to you.

2. 2

   Get one of each piece:

   eye of the Duke, Leviathan's lure, siren's staff and executioner's axe head.

3. 3

   Have 75 Magic.

   It cannot be boosted for this, so a wizard's mind bomb or magic potion will not help.

4. 4

   Carry 2,000 blood runes with the four pieces and combine them.

   The axe takes 5 ticks to make and gives 400 Magic XP.

One thing the original poll blog got wrong: it said you would need the whole quest to wield the axe. In game the only wield requirements are 80 Attack and 80 Strength, so a bought axe works on any account with those levels.

Soul Stacks and the Behead Special

You gain a soul stack every time you attack with the axe, hits and misses alike, up to a cap of five. Each stack adds 6% to your Strength level, so five stacks are worth +30%, and it is additive with Piety's 23% instead of multiplying it. A stack is added after the damage of the swing that made it, so a swing never benefits from its own stack. Stacks only boost the axe.

The 22 July 2026 update made the axe much easier to run. Gaining stacks no longer costs you hitpoints (it used to cost 8 per stack), you can now go 50 ticks without attacking before a stack starts to decay instead of 20, and the strength bonus went from +121 to +125. Stacks decay one at a time, so a short walk between monsters no longer resets you.

Behead uses all your stacks and no special attack energy. Each stack adds 12% accuracy and 6% to both maximum and minimum damage, so a five-stack Behead has +60% accuracy, +30% max hit and a floor of 30% of your max hit. The cost is that your Strength boost goes with it and you rebuild from zero, so it works best as a finisher, or just before a break in the fight where your stacks would decay anyway.

Where the Soulreaper Axe Is Best

The axe is strongest wherever you can keep five stacks up and the target is too small for a scythe to land all three hits. Against 3x3 and bigger monsters the scythe of vitur usually stays ahead.

• Vardorvis. The wiki lists it as the best weapon there, because his 2x2 size and high Defence hold the scythe back.
• Araxxor, as a strong second choice. The wiki ranks it level with the Inquisitor's mace, behind only the scythe, and the long fights keep five stacks up. The Araxxor guide covers the rest of that setup.
• Slayer tasks and Nightmare Zone. Aggressive monsters mean very little input is needed to hold five stacks.
• Not Duke Sucellus enrage. He drops to a four-tick cycle there, and a five-tick weapon like this one can only safely attack every second attack.

Which Boss to Farm First

All four pieces are required, so the order only decides how pleasant the grind is. Duke Sucellus is the usual starting point because his fight is slow and countable. The siren's staff is the most common piece and the axe head the rarest, so if you burn out easily, leave Vardorvis for last.

Each boss also drops a tablet at roughly 1/25 that unlocks its ring of shadows teleport, and it only drops until you have it. Your first few trips to each boss are the slow ones.
