Artifacts

Artifacts are Game Modifiers that are found in the world in-game. A guide for tips and notes on playing with artifacts can be found here

Unlocking
To unlock Artifacts you need to use the correct Artifact Code in Sky Meadow, using the Compound Generator below the map, then interacting with the laptop. A Portal to the trial for that Artifact in Bulwark's Ambry will spawn.

The Compound Generator will cycle in the order: square, circle, triangle, diamond (■ ● ▲ ♦)

In Bulwark's Ambry, the Artifact whose trial is being attempted will be active and an Artifact Key will be on an elevated block in front of the Artifact Reliquary. The player must give the Artifact Key to the Artifact Reliquary, which will cause monsters to start spawning, with more Artifact Keys dropping from randomly killed monsters. Using an Artifact Key will remove them from all player inventories.

Upon destroying the Artifact Reliquary, the Artifact can be taken and a portal to a First Stage will appear.

Artifact of Sacrifice Drop Chance
The drop chance is equal to
 * See: exp and difficultyCoeff for more details on how these are calculated

Approximate drop chances for an average game of 1-4 players, from stage 1-8 over 60 minutes:
 * 6-30% for Beetle, Lesser Wisp, Jellyfish, Lemurian
 * 13-37% for Hermit Crab, Alloy Vulture, Imp
 * 16-40% for Beetle Guard, Bighorn Bison, Stone Golem, Brass Contraption
 * 23-47% for Elder Lemurian, Clay Templar
 * 27-51% for Greater Wisp
 * 35-60% for Beetle Queen, Clay Dunestrider, Stone Titan, Wandering Vagrant, Imp Overlord, Magma Worm, Solus Control Unit
 * 48-73% for Overloading Worm

Notes:
 * Add 12% for elite versions
 * There can be variance depending on difficulty, game time and other factors, however these numbers serve to give a general min/max chance
 * Teleporter bosses (-16%), monsters that spawn when the teleporter is charging (-4%), and monsters pre-spawned when a map starts (-8%) have lower chances (first stage reductions are smaller, -1-3%)
 * Drop chance for these monsters is unknown, it is likely around that of similarly tiered monsters: Mini Mushrum, Parent, Solus Probe, Void Reaver, Alloy Worship Unit, Aurelionite, Grovetender, Scavenger, Twisted Scavenger
 * On the first stage only when the game starts, the drop chance will decrease slightly over time, by ~0.1-1% until the monsters level up (2-7 minutes) or the next stage is started
