Artifacts in Project Silverfish can shift the course of a run in seconds. Some are practical and safe, others are strange or cursed, and a few are downright essential if you’re planning on surviving the later zones.
This guide documents all known artifacts as of version 0.2.4, split into three categories:
- Active Artifacts – usable tools with cooldowns or triggers.
- Consumables – single-use effects.
- Passive Artifacts – always-on buffs or debuffs.

Passive Artifacts
These artifacts apply effects simply by being in your inventory. Some grant strong buffs, others have serious drawbacks — and a few do both.

Final Notes
- Black Stone is cursed. Do not pick it up unless you’re ready for serious downsides.
- White Impala acts like a one-time cheat death mechanic.
- Drill Head is absurdly expensive and heavy, but its Ether benefits may be worth it for caster builds.
- Tesseracts are highly situational. Keep a few around for fast travel or escape plans.
