Artifact of Vengeance Risk of Rain 2

Artifact of Vengeance

Your relentless doppelganger will invade every 10 minutes. An Umbra copies your entire build and spawns at the Teleporter every 10 minutes. It hits for only 4% of your damage but has all your items - proc explosions are the real danger. On death it drops one item from its inventory. Net effect on long runs: free items on a timer. The code is uniquely hidden in the game's logbook, not on a stage tablet.

How the Umbra Works

Spawns every 10 minutes

Timer-based - cannot spawn on stages with a stopped timer. Spawns near the Teleporter on normal stages; at your current position on stages without one.

Copies everything

All items, all equipment, all hidden items (including DrizzlePlayerHelper). The Umbra is your build turned against you. The more items you have, the more dangerous it becomes.

3-second invincibility

Hidden Invincibility buff for 3 seconds after spawning. You cannot kill it immediately on arrival. Plan around the brief window before it starts attacking.

Counts as a boss

HP bar shown at top of screen. Armor-Piercing Rounds deal +20% damage to it. Screen turns deep purple while alive. Susceptible to Old Guillotine below 13% HP.

Deals 4% of player damage

Umbra damage is multiplied by 0.04. Despite having your full build, it hits far softer than you. The threat comes from item procs (Behemoth explosions, band procs) rather than raw hits.

Drops one random item on death

One item from its inventory, weighted toward commons due to drop chance bias. With Command active, this becomes a chooseable Command Essence. Free item every 10 minutes.

Engineer turrets count

Engi turrets inherit all items including the Vengeance special item. Each killed turret also drops an item. Purple screen persists until all turrets holding the item are dead.

With Swarms: 2 Umbrae

Two doppelgangers spawn per invasion, each at half max HP. Doubles the free item drops but also doubles the chaos.

The Umbra Hits Soft, But Procs Are Dangerous

4% damage multiplier means a direct hit from your Umbra barely dents you. The real threat is item procs - if you have Brilliant Behemoth, the Umbra's explosions fire at full proc rate and hit for 60% bonus damage. Avoid running into its AoE radius and burst it down quickly with Armor-Piercing Rounds.

Best Items Against the Umbra

Armor-Piercing Rounds
Armor-Piercing Rounds
Umbra counts as a boss - APR deals +20% damage per stack. One of the most efficient ways to burst it down quickly.
Dio's Best Friend
Dio's Best Friend
Insurance against a bad Umbra timing. One free death means an early Umbra on a weak build won't end the run.
Old Guillotine
Old Guillotine
Umbra is an elite-susceptible boss. Old Guillotine executes it below 13% HP - instant kill below threshold.
Harvester's Scythe
Harvester's Scythe
High crit healing keeps you alive during the purple phase when all attention is on the Umbra.
Tougher Times
Tougher Times
Block chance against Umbra proc explosions (Behemoth, bands). Umbra hits soft but its AoE procs still connect.
Lens-Maker's Glasses
Lens-Maker's Glasses
Stacking crit lets you burst the Umbra in the window after its invincibility fades. Speed kills matter.

Best Combos

Vengeance + Sacrifice
Vengeance + Sacrifice

Umbra drops an item on death anyway. With Sacrifice active, every 10-minute invasion also gives you a free enemy-kill item drop. Item generation accelerates over long runs.

Vengeance + Command
Vengeance + Command

The Umbra's dropped item becomes a Command Essence. Free chosen item every 10 minutes. On long loops with multiple Umbra kills this compounds into major item advantage.

Vengeance + Swarms
Vengeance + Swarms

Two Umbrae per invasion, each at half HP. Two free items every 10 minutes. Both are weaker individually - easier to burst down with AoE. Good net positive.

Vengeance + Glass
Vengeance + Glass

Your Umbra has 5x damage output with 10% health. Despite the 4% damage multiplier, Glass proc explosions from the Umbra can still connect and one-shot you. Extremely dangerous.

Vengeance + Evolution
Vengeance + Evolution

Umbra gains items alongside monsters between stages. A late-loop Umbra with Evolution stacks has proc chains that can be lethal even at 4% multiplier. Very high difficulty.

Vengeance alone
Vengeance alone

Free item every 10 minutes on average. The Umbra hits softly (4% damage) and is counterable with burst. A net positive on long runs. Good for challenge and item farming.

Tips

Kill it fast after invincibility fades. 3 seconds of invincibility on spawn - then burst it immediately. Armor-Piercing Rounds, Old Guillotine, and high crit make the kill window short.
Long runs are net positive. Each Umbra kill drops a free item. On loops 2, 3, 4+ the Umbra spawns multiple times per loop. Command turns every drop into a chosen item.
Stall if needed. The Umbra spawns on the teleporter. If you're mid-teleporter event, it appears right at the boss fight location. Complete the event first if timing is bad.
Engineer players: clear turrets after the Umbra dies. The purple screen filter stays active until all turrets holding the Vengeance item are dead. Kill leftover turrets to restore normal visibility.
Watch your own Behemoth with Chaos active. Chaos + Vengeance is particularly dangerous because friendly fire from the Umbra's proc explosions combined with your own can wipe you instantly.
Trial of Vengeance: solo is manageable. You kill 3 Umbrae between key uses in a solo run. Each is your current build so come strong from Stage 5. Multiplayer scales to one Umbra per player per key use - coordinate kills.
