What It Does

This single-use consumable applies Demon’s Hand at the Pal Surgery Table . The surgery itself is free; the implant is consumed. The passive is the strongest work passive in the game:

• Work Speed +90% — ahead of Remarkable Craftsmanship (+75%) and Artisan (+50%), and it stacks with both.
• SAN drops 15% faster — the one drawback; Positive Thinker cancels most of it.
• World Tree harvestables won't vanish when approached — the shared World Tree effect, covering both the Pal and its trainer.

Where to Get It

Disposable implants come from one place: the Ancient Relic Recycler . Every recycled Ancient Relic — any grade, including cheap Decayed ones — rolls exactly one implant from a 16-implant pool, so this one lands at 6.25% per recycle. The only other source of the passive is a lucky roll on wild Pals spawned inside the World Tree. Because the implant is one-and-done, spend it on a finished dedicated crafter. See the Ancient Relics guide for the reward tables and the implants guide for how surgery works.
