Trial of Enigma Risk of Rain 2

Artifact of Enigma

Spawn with a random equipment that changes every time it's activated. Every use rerolls your equipment slot into a new random one, carrying over the cooldown. Most equipment can appear including lunar items - but Milky Chrysalis, The Crowdfunder, Effigy of Grief, Executive Card, and Seed of Life are excluded. Elite equipment won't reroll even if you try. The code is hidden inside Bulwark's Ambry itself, behind the giant floating cube.

Code and Location

Code Pattern
Diamond top-left, Triangle corners middle, Circle + Diamonds bottom
Bulwark's Ambry Risk of Rain 2
Code Location: Bulwark's Ambry

Behind the giant floating cube visible in the background of the arena. One of two codes hidden inside special realms (Vengeance is in the A Moment, Fractured logbook). You need to reach the Ambry first to find it.

Excluded Equipment

These items will never appear as a reroll result. Every other equipment - including lunar items - is fair game.

Milky Chrysalis
Milky Chrysalis
Would grant near-infinite flight for entire stages - too powerful
The Crowdfunder
The Crowdfunder
Toggle mechanic incompatible - triggers 5s cooldown but no reroll
Effigy of Grief
Effigy of Grief
Permanent placement effect would be too disruptive
Executive Card (SotV)
Executive Card (SotV)
Excluded from the random pool
Seed of Life (SotS)
Seed of Life (SotS)
Excluded from the random pool
Elite Equipment
Cannot be activated - activating does nothing, no reroll
Crowdfunder Edge Case

The Crowdfunder doesn't get a new equipment when toggled - it triggers a 5-second cooldown but the reroll only happens on items picked up after it's used. Toggling Crowdfunder while holding it won't cycle to a new equipment.

Key Mechanics

Cooldown carries over. The new equipment inherits the cooldown of the one you just activated. Use equipment with short cooldowns to cycle faster.
Equipment Drone and Scavenger also trigger rerolls. Any entity's equipment activation rerolls under Enigma - including allied Equipment Drones. Scavengers also reroll their own equipment when they use it.
Lose your slot, lose your Enigma. Giving equipment to an Equipment Drone or using a Cleansing Pool (for lunar equipment) removes your item and you don't get a replacement until the next stage.
Preon Accumulator quirk. Fires immediately when rolled but no charge animation shows. Cannot activate for a new item while Preon is charging - wait for it to detonate first.
Milky Chrysalis exception. Excluded from rolling because it would grant near-infinite flight for the entire stage. If you somehow obtain it, activating it gives the full 15-second flight, and another activation still won't cycle it.

Best Items for Enigma Runs

Fuel Cell
Fuel Cell
Extra equipment charges + 15% cooldown reduction per stack. More Enigma activations per fight. Stack for near-constant equipment use.
Ocular HUD
Ocular HUD
+10% crit chance per stack. Equipment-independent benefit that scales every run regardless of which equipment rolls.
Royal Capacitor
Royal Capacitor
One of the best Enigma outcomes. Lightning bolt does 3000% damage. When it rolls this, use it immediately before it rerolls.
Preon Accumulator
Preon Accumulator
4000% damage on detonation. Fires when rolled but won't show the charge animation. Can't get a new item while it's charging.
Spinel Tonic
Spinel Tonic
Lunar equipment - CAN be rolled by Enigma. Massive stat boost for 20 seconds but Tonic Affliction debuff on end. Strong when it rolls.
Backup Magazine
Extra utility charges. Not equipment-specific but helps with skill-based survivors who can use Enigma procs between abilities.

Best Combos

Enigma + Command
Enigma + Command

Choose every item while equipment rotates randomly. Command locks down your item build while Enigma adds variety to your equipment slot. Strong and controllable.

Enigma + Sacrifice
Enigma + Sacrifice

Items from monster kills while equipment changes every use. If Enigma rolls a strong damage equipment (Royal Capacitor, Preon) during a kill chain, the synergy is excellent.

Enigma + Glass
Enigma + Glass

5x damage means any equipment that deals damage (Royal Capacitor, Preon Accumulator) is devastating. High risk if Enigma rolls defensive equipment at the wrong moment.

Enigma alone
Enigma alone

Fun and low-risk modifier. Equipment slots are usually underutilized - Enigma ensures you always have something usable. High variance but rarely run-ending.

Enigma + Evolution

Random equipment every use while enemies grow stronger each stage. Good practice for learning all equipment effects under pressure.

Enigma + Metamorphosis

Random survivor each stage AND random equipment. Double RNG. No build control at all. Pure chaos run for experienced players.

Frequently Asked Questions

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

The Artifact of Enigma gives all players a random equipment at the start of a run that changes to a new random equipment every time it's activated. Equipment cooldown carries over to the new item. Most equipment can roll, but Milky Chrysalis, The Crowdfunder, Effigy of Grief, Executive Card, Seed of Life, and Elite equipment are excluded.

What is the Artifact of Enigma code?

The Artifact of Enigma code is ♦■■ ▲■▲ ●♦♦ - Diamond-Square-Square on top, Triangle-Square-Triangle in the middle, Circle-Diamond-Diamond on the bottom. The code is found in Bulwark's Ambry itself, behind the giant floating cube visible in the background distance.

Where is the Artifact of Enigma code?

The code is in Bulwark's Ambry - the hidden realm where you complete all artifact trials. Behind the giant floating cube visible in the background of the arena. You need to access the Ambry at least once and explore behind the cube to find it. It is one of the harder-to-find code locations since it requires reaching the Ambry first.

Can Enigma roll lunar equipment?

Yes. Lunar equipment like Spinel Tonic, Glowing Meteorite, and Effigy of Grief - wait, Effigy of Grief is excluded. But Spinel Tonic, Glowing Meteorite, and other lunar equipment CAN be rolled by Enigma. The excluded items are specifically: Milky Chrysalis, The Crowdfunder, Effigy of Grief, Executive Card, and Seed of Life.

What happens if you give your equipment to an Equipment Drone with Enigma?

If you give your equipment to an Equipment Drone or use a Cleansing Pool (for lunar equipment), you lose your equipment slot and do not receive a new one until the next stage. Keep your equipment through all sources while Enigma is active.

Does the Preon Accumulator work with Artifact of Enigma?

Yes, but with quirks. When Enigma rolls a Preon Accumulator, it fires but does not show the charge-up animation. While a Preon is charging, you cannot activate the equipment to get a new one via Enigma - you must wait for it to fire first.
