What it does.

Artifact of Chaos
Game text: «Friendly fire is enabled for both survivors and monsters alike.»

Friendly fire for everyone: your attacks hurt your allies and monsters hurt each other. Your own explosions and lightning reach you too.

Solo it is almost an advantage: monsters fight each other and big bosses kill the small ones. In a group, careful with area attacks and the Ukulele.

It is in the base game. 13.6% of all Risk of Rain 2 players on Steam have it, from Steam's public stats on 31 October 2026.

Read top to bottom, as shown here: three rows of three shapes. Each slot on the generator changes shape when pressed, in this order: square ■, circle ●, triangle ▲, diamond ♦.

// how to unlock it

How to unlock it.

  1. Reach stage 5: Sky Meadow or Helminth Hatchery.
  2. Find the Compound Generator: on Sky Meadow it is under the map, in a room you drop into through a hole; on Helminth Hatchery, at the very top.
  3. Enter the code in the nine slots and use the laptop next to them. A purple portal opens.
  4. Enter the portal: it leads to Bulwark's Ambry, with the artifact already active for the trial.
  5. Take the Artifact Key in front of the Artifact Reliquary and use it on it. Monsters start spawning and drop more keys; each key takes a chunk off the reliquary's health.
  6. Break it: the artifact is yours for good and a portal to a first stage opens so you can keep going.

In co-op, the group can enable any artifact that any player has unlocked. Artifacts are chosen in the menu before the run starts.
