Allows turning Ymir's Flesh, found in forest or rock locations, into Ymir's Spirit. You can buy extractors from the trader in the Gate Between Worlds location and then install them in the home camp. Extractors can only be installed on the ground.

You will be receiving extra Ymir's Spirit as a result of the extractor's work for each slot filled completely with Ymir's Flesh (max. of 60 units of Ymir's Spirit per slot).

The extractor can be robbed during a raid! A raider can take Unstable Ymir's Spirit, which he then needs to use next to their extractor in order to turn Unstable Spirit into regular Ymir's Spirit.

The owner of the robbed extractor can fight off, take away, and use Unstable Spirit before the raider carries it away from the home camp. Unstable Spirit also turns into the regular one when used.
