What a Forsaken Power is

Every Forsaken boss drops a trophy. Hang that trophy on the Sacrificial Stones — the ring of standing stones near the centre of every generated world map — and the boss’s power becomes yours to activate.

Two rules shape how you use them:

  • Only one power can be set at a time. To change which one you carry, walk back to the Sacrificial Stones and interact with a different mounted trophy.
  • Powers are timed buffs, not passive gear. Activating one locks you into a short animation. Treat them as buttons you press before a push, not something that is always on.

Verified against 1.0 release: all power effects listed below, including duration, are confirmed from the Call to Arms rework (patch 0.221.4) and cross-checked against 1.0 boss pages and independent guides. See our verification workflow.

All Forsaken Powers

The exact values below are from the Call to Arms rework (patch 0.221.4) — the update that rebalanced every Forsaken Power. If you are reading this on an older build, the numbers may differ.

Boss Biome Effect (Call to Arms values)
Eikthyr Meadows 60% reduced stamina usage for running, jumping and swimming
The Elder Black Forest 60% increased chopping and mining damage, 30% increased health regeneration
Bonemass Swamp 25% resistance versus pierce, slash and blunt; 100% reduced block stamina usage, 5 stamina returned per block
Moder Mountain A tailwind while sailing (lasts 300s), +300 carry weight, 10% increased movement speed, 50% frost resistance
Yagluth Plains 50% lightning resistance, +25 Farming skill, 10% increased damage
The Queen Mistlands 100% increased Eitr regeneration, 100% reduced sneak cost, 50% poison resistance
Fader Ashlands 100% increased Adrenaline gain, 50% reduced stagger when hit, 50% fire resistance

Note on versions: older pre-Call-to-Arms material describes these effects in broad terms (e.g. Yagluth as “broad elemental resistances”). The table above reflects the current 1.0 values from the official patch notes — use these, not the older descriptions.

Which power to set, by situation

  • Boss fights and dense combat: Bonemass. The physical resistance covers most of what hits you, and free blocking changes the whole risk calculus of a shield build.
  • Long exploration, running, swimming, climbing: Eikthyr. Stamina is the resource everything else spends, so this stays useful from the Meadows to endgame.
  • Gathering runs and mining: The Elder. Faster chop and pickaxe damage shortens every resource loop, and the health regeneration helps when you are working far from a bed.
  • Ocean crossings and hauling ore: Moder. The guaranteed tailwind removes the single biggest variable in sailing, and the carry-weight bonus is why players set it for metal runs.
  • Staff and magic builds: The Queen. Doubled Eitr regeneration is the difference between a magic build that works and one that stalls.
  • Fire-heavy regions: Fader. Fire resistance plus reduced stagger is built for the Ashlands and for endgame content that keeps hitting you while you burn.
  • Farming and lightning-heavy fights: Yagluth. Situational, but the Farming bonus is the only way to accelerate crops.

Using powers in a group

Each player unlocks and sets their own powers, so a party can cover several situations at once: one player on Bonemass for the fight, one on Eikthyr for the approach, one on Moder for the sail home. Coordinate before you leave — switching means walking back to the Sacrificial Stones, which are always at the world centre and never near where you are standing.

A note for base builders: the area immediately around the Sacrificial Stones is protected, so you cannot build there. Plan your portals and outposts around it.

Frequently asked questions

How do I get a Forsaken Power?
Defeat a boss, take the trophy it drops, and hang it on the Sacrificial Stones — the ring of standing stones at the centre of the world map. The matching power then becomes available to you.
Can I have more than one Forsaken Power active?
No. Only one power can be set at a time, and switching means returning to the Sacrificial Stones and interacting with a different mounted trophy. Activate the power you have set with the Forsaken Power key (F by default on PC).
Which Forsaken Power is the best?
Bonemass for fighting (broad physical resistance plus a block-stamina bonus), Eikthyr for everything else (stamina is the resource the whole game runs on), Moder for hauling and ocean crossings, and The Queen for staff builds. The right answer changes with what you are about to do.
Do Forsaken Powers work in multiplayer?
Yes. Each player unlocks and sets their own powers. In a group it is worth coordinating who activates which power before a boss push, since you only get one active at a time per player and switching requires a trip back to the stones.
