Risk of Rain 2 has 22 named bosses across base game and three DLC expansions. Teleporter bosses gate every stage. Special and optional bosses guard rare rewards. Final bosses define each DLC's ending. This page covers every boss with stats, locations, boss item drops, quick tips, and full guide links where we have them.
Every boss in the game. Filter by type. Bosses with a Full Guide button have detailed stat pages with attack breakdowns and survivor matchups.
Understanding these systems will change how you approach every teleporter event.
Activate the Teleporter to begin the event. One boss spawns immediately, chosen from the stage-specific pool. The boss must die before the Teleporter finishes charging. After roughly 15 minutes into a run, bosses also begin spawning in the open world as regular enemies.
Doubles the credits available to the boss director per activation - meaning harder or more numerous bosses. In return, the Teleporter drops 100% more items. Each extra item also has a chance to be a boss item. Stack Shrines early when boss credits are low and the risk-to-reward ratio is in your favor.
Every boss gains HP and damage per level, which increases continuously with time. Playing slowly is a direct threat. After looping (clearing Stage 5 and restarting), bosses are significantly stronger and gain additional attack patterns at lower HP thresholds. Monsoon accelerates this rate faster than Drizzle.
Mithrix, Voidling, and Solus Wing all have Adaptive Armor. Each hit grants temporary armor equal to 30 per 1% of max HP dealt, capping at 400 and decaying at 40 per second. Sustained consistent fire beats burst DPS every time against these bosses. Symbiotic Scorpion permanently reduces armor per hit.
Each boss has a small chance to drop its unique yellow boss item when it is the Teleporter Boss. Shrine of the Mountain increases the number of items dropped, giving more rolls. Trophy Hunter's Tricorn (SotV DLC) instantly kills any boss and guarantees its item. Yellow Item Scrap can be used in Overgrown 3D Printers.
Any boss has a 3% chance to drop its Monster Log if you have not yet collected it. This chance is affected by 57 Leaf Clover (increases chance) and Purity (decreases chance). Voidling only drops its log during the final phase. Twisted Scavengers have no logbook entry.
Teleporter bosses are drawn from a stage-specific pool, not randomly from all bosses. The table below shows the possible pool per stage group. On higher loops and Monsoon difficulty, more powerful variants and multiple simultaneous bosses become common.

Based on mechanical complexity, damage potential, and what happens when things go wrong. Difficulty increases significantly on Monsoon and in post-loop runs.
Each boss has a small chance to drop its yellow boss item when it serves as the Teleporter Boss. Shrine of the Mountain gives more item drop rolls. Trophy Hunter's Tricorn (SotV DLC) guarantees the boss item on kill and is consumed on use.

Risk of Rain 2 has 22 named bosses across base game and all DLC content as of the Alloyed Collective expansion. This includes 12 teleporter bosses, 5 special/optional bosses, 4 final bosses, and 1 hidden final boss. The total grows with each DLC release.
Solus Wing from the Alloyed Collective DLC has the highest mechanical skill demand: 1,000 base armor that requires destroying Memory Module weak points, four escalating attack phases, Heat Vents and laser grids in the late phase. Voidling's Nullifier Black Hole is the single most lethal individual attack in the game since it ignores all invulnerability.
Defeating the Teleporter Boss drops one Uncommon (green) item per player. If the boss has a yellow boss item, each item drop has a small chance to be the boss item instead. Shrine of the Mountain gives more item drops. Trophy Hunter's Tricorn guarantees the boss item on kill. Some bosses (Aurelionite, Twisted Scavenger) don't follow the standard drop rules.
The standard final boss is Mithrix at Commencement. The Survivors of the Void DLC adds Voidling at The Planetarium as an alternate. The Alloyed Collective DLC adds Solus Wing as its final boss, with Solus Heart as a secret hidden final boss accessed after defeating Solus Wing.
Multiple bosses spawn because of time pressure or Shrine of the Mountain activations. After around 15 minutes elapsed in a run, the boss director has more credits to spend, which can mean multiple bosses or harder elite bosses. Each Shrine of the Mountain doubles the director's credits per activation, increasing both difficulty and loot.
Yellow boss items drop from Teleporter Bosses with a small random chance, replacing one of the standard item drops. Activating Shrines of the Mountain increases the number of drops, giving more chances. Trophy Hunter's Tricorn (SotV DLC) instantly kills any capable boss and guarantees its boss item. Yellow Item Scrap from Scrappers can also be used in Overgrown 3D Printers.
