Project Silverfish Artifact Guide (v0.2.4)

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.

All tables below include artifact name, effects (if any), Ether cost, price, weight, and notes if relevant.

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.
