Artifact of Chaos Risk of Rain 2

Artifact of Chaos

Friendly fire is enabled for both survivors and monsters. Solo, Chaos is a net positive if you avoid explosive items - monsters kill each other and you can exploit their friendly fire. In multiplayer it becomes increasingly dangerous as proc-heavy builds fire AoE into teammates constantly. The self-damage items list is what defines whether this artifact helps or hurts you.

Solo vs Multiplayer

Solo Play
+Only your own AoE items deal self-damage
+Monsters kill each other - bait enemies into groups
+Elite AoE (Overloading, Glacial freeze) hits other enemies
+Use tanky enemies as pseudo-cover against ranged attackers
+Net positive if you avoid explosive items
Multiplayer
-Teammates deal full damage to each other
-AoE skills and items hit allies constantly
-Nearly unplayable in late runs with proc-heavy builds
-Drones and turrets can kill teammates
-Requires tight coordination and no explosive items
Solo Chaos Is Underrated

Most players assume Chaos is a pure negative. Solo, it is not. Monsters dealing friendly fire to each other means every tight pack of enemies starts self-destructing. Pair with Sacrifice and melee survivors that naturally avoid AoE procs. Avoid Brilliant Behemoth entirely.

Items That Deal Self-Damage

Any item with an AoE proc can hit you. Avoid these or position carefully.

Brilliant Behemoth
All attacks explode in a radius - that radius hits you too
Will-o'-the-Wisp
Kill explosion lava pillar can catch you if you're inside the radius
Kjaro's Band
Runic flame tornado triggered by high damage hits can arc back
Runald's Band
Runic ice blast from high damage hits
Sticky Bomb
On-hit bomb that detonates on the target - radius catches you at close range
Gasoline
Kill ignition radius hits nearby players and yourself
Luminous Shot (SotS)
Lightning strike proc from secondary charges - AOE can self-hit

Allies That Deal Friendly Fire

Drones
All drone types deal friendly fire to players and each other. Careful positioning matters.
Devotion Lemurians
Artifact of Devotion followers deal friendly fire damage. Keep distance during their attacks.
Squid Polyp Turrets
Squid Turrets from Squid Polyp deal friendly fire. Don't place them in chokepoints with allies nearby.
Queen's Gland Guards
Beetle Guards from Queen's Gland on an Umbra do NOT get the friendly fire damage reduction. They deal full 4x Beetle Guard damage to you.
Trial of Chaos - May Need More Than 4 Keys

With Chaos active in Bulwark's Ambry, monsters kill each other and gain experience. If they level up, the Artifact Reliquary also gains HP and may require more than the standard 4 keys to destroy. Let enemies fight each other to slow XP gain, or kill them quickly before they level.

Best Combos

Chaos alone (solo)

Genuinely good solo modifier if you avoid explosive items. Monsters killing each other speeds up runs and reduces incoming damage. Use melee or non-proc ranged builds.

Chaos + Sacrifice

Monsters killing each other counts as kills - they drop items. Free item generation from enemies fighting themselves. Very strong solo combo.

Chaos + Kin

One monster type floods the stage, and they all fight each other. Low-health types like Wisps or Jellyfish will self-annihilate rapidly generating drops with Sacrifice.

Chaos + Glass

You deal 5x damage and die to a single hit. Your own AoE items kill you in one proc. Extremely high skill ceiling - works if you use zero AoE items and stay mobile.

Chaos + Swarms

Doubled enemies, all fighting each other constantly. Massive chaos, lots of stray damage flying around. AoE items are instant death. Pure chaos run.

Chaos (multiplayer)

Only recommended with full voice communication and a coordinated team that avoids AoE builds. Generally a meme run rather than a serious one by late stages.

Tips

Pick Mercenary or Loader solo. Both have evasion tools, neither relies on AoE procs, and both deal high burst damage. Mercenary's dodge and Loader's hook let you fight at range from your own melee hits.
Bait tanky enemies into Lemurian fire. Stone Golems standing in a Lemurian line of fire take chip damage constantly. Let enemies thin each other before engaging.
Tougher Times is essential. A 15% chance to block any hit matters a lot when stray friendly fire is constant. Stack it aggressively.
Skip Brilliant Behemoth entirely. It is normally a top-tier red item. With Chaos active it is a run-ender. Pass on it from Command Essences or avoid buying it from chests.
In multiplayer, agree on a no-AoE rule. The run is playable if every player runs precision builds (Railgunner, sniping Huntress, Commando). One player with Behemoth wipes the team.
Engineer turrets still deal friendly fire. Engineer turrets fire into the same area as you and will hit you if you are in their line of fire. Position them behind you, not beside you.

Frequently Asked Questions

What does the Artifact of Chaos do in Risk of Rain 2?

The Artifact of Chaos enables friendly fire for both survivors and monsters. Players take damage from their own AoE items (Brilliant Behemoth, Will-o'-the-Wisp, Sticky Bomb etc.), from allied drones and turrets, and in multiplayer from teammates. Monsters also deal friendly fire to each other, which solo players can exploit by baiting enemies into groups.

What is the Artifact of Chaos code?

The Artifact of Chaos code is ●▲● ●▲● ●▲● - all three rows are Circle-Triangle-Circle. The code appears in two locations in Abandoned Aqueduct: between one of the tar pits and the tunnel, and inside the Ancient Gate cave.

Is the Artifact of Chaos good solo?

Yes, solo Chaos is a net positive if you avoid explosive items. Monsters killing each other reduces the enemies you have to deal with and generates free drops with Artifact of Sacrifice. Melee survivors like Mercenary or Loader who avoid AoE procs benefit the most. The danger is your own item build accidentally killing you.

Which items are dangerous with Artifact of Chaos?

Any item with an AoE component can self-damage: Brilliant Behemoth, Will-o'-the-Wisp, Kjaro's Band, Runald's Band, Sticky Bomb, Gasoline, and Luminous Shot. Allied entities - drones, Devotion Lemurians, Squid Polyp turrets - also deal friendly fire damage.

What happens during the Trial of Chaos?

The Trial of Chaos in Bulwark's Ambry has Chaos active during the trial. Monsters kill each other and gain experience from those kills, causing them to level up. If monsters level up enough, the Artifact Reliquary also gains HP and may require more than the standard 4 Artifact Keys to destroy.

Does the Artifact of Chaos work with Artifact of Sacrifice?

Yes - this is one of the best Chaos combos solo. Monsters that kill each other count as kills and drop items under Sacrifice. You get free item generation from enemies fighting themselves without needing to be nearby.
