Risk of Rain 2 Bosses: Every DLC Through Hallowed Concepts

Updated 2026-10-28: Corrected where the Shrine of Descent appears: at a random spot when a stage starts, not next to the Teleporter. On October 20 we added the Hallowed Concepts bosses (Lynx Totem, Shruum, Anima Harvester, Echo of Providence and its Corroded Wurms), corrected the Mithrix ending and removed an unsourced launch-review figure for Seekers of the Storm.

TL;DR: Confirmed bosses span the main stage rotation (Beetle Queen, Clay Dunestrider, Grandparent, and others) up through Mithrix, the final boss at Commencement. Survivors of the Void, Alloyed Collective and Hallowed Concepts each added their own bosses. Alloyed Collective, not Seekers of the Storm, is the actual 2025 DLC: it added 2 survivors, 2 new Teleporter Bosses, 7 stages, and 18 items, and launched to a much cleaner reception than its predecessor's rocky debut.

What are the confirmed bosses in Risk of Rain 2? (quick answer)

The main rotation includes Beetle Queen, Clay Dunestrider, Grandparent, Grovetender, Imp Overlord, Magma Worm, Overloading Worm, Scavenger, Stone Titan, and Wandering Vagrant, confirmed via the game's own wiki. The final boss is Mithrix at Commencement: beat him and escape to win the run.

Key takeaways

• Main-rotation bosses confirmed: Beetle Queen, Clay Dunestrider, Grandparent, Grovetender, Imp Overlord, Magma Worm, Overloading Worm, Scavenger, Stone Titan, Wandering Vagrant
• Mithrix is the final boss at Commencement; looping happens before him, at the Stage 5 Teleporter
• Survivors of the Void added Void Devastator, Xi Construct, and the Voidling
• Alloyed Collective (Nov 2025) added Solus Amalgamator and Alloy Hunter as new Teleporter Bosses
• Alloyed Collective's own new final boss was deliberately spoiler-redacted by the developers at launch
• Hallowed Concepts (Oct 2026) added Lynx Totem and Shruum as Teleporter bosses, plus two secret fights: the Anima Harvester and the Echo of Providence
• The 2025 DLC is Alloyed Collective, not Seekers of the Storm (which released August 2024)

The core boss rotation

Ten bosses make up the confirmed base-game rotation, each tied to specific stages rather than appearing everywhere: Beetle Queen, Clay Dunestrider, Grandparent, Grovetender, Imp Overlord, Magma Worm, Overloading Worm, Scavenger, Stone Titan, and Wandering Vagrant. Mithrix, "King of Nothing," closes out the main progression at Commencement. Beat him, reach the Rescue Ship and you've won. If you want the run to keep going, the choice comes one stage earlier: align the Stage 5 Teleporter with the planet instead of the moon and the run loops back to Stage 1 with everything scaled up.

Elite enemies aren't the same as bosses

Separately from named bosses, any regular monster can spawn as an elite with a powerful modifier attached, confirmed via the wiki's own elite-affix list: Blazing, Overloading, Glacial, Mending, and Gilded at the first tier, with Malachite, Celestine, Twisted, and Collective (the newest, added by Alloyed Collective) at a second, tougher tier. Perfected and Voidtouched exist as special elite variants on top of that. An elite-modified regular enemy can be more dangerous than an actual boss fight depending on the affix and the stage, so don't assume "boss" and "elite" mean the same threat level.

DLC bosses: Survivors of the Void and Alloyed Collective

Survivors of the Void added Void Devastator and Xi Construct as new bosses, plus the Voidling as a special end-of-run encounter tied to that expansion's content.

Alloyed Collective, confirmed directly via its official Nov 18, 2025 patch notes, added Solus Amalgamator and Alloy Hunter as "2 New Teleporter Bosses." Worth noting separately: Solus Control Unit, sometimes assumed to be Alloyed Collective content because of the shared "Solus" naming, actually predates the DLC, coming from an earlier "Skills 2.0" update, even though it does appear in some Alloyed Collective stages. Don't credit it to the new expansion.

Alloyed Collective's own new final boss is a genuinely unusual case: the developers deliberately redacted its name in their own official patch notes as an intentional launch-day spoiler tease. The community-maintained wiki, updated after players found it in-game, names it Solus Heart, encountered in a location called Neural Sanctum. Treat "Solus Heart" as a post-launch community identification rather than something the developers themselves confirmed on day one, since that's genuinely what happened here.

The actual 2025 DLC, and why the confusion happens

Here's the correction worth making explicitly: if you've seen coverage calling Seekers of the Storm "the 2025 DLC," that's wrong. Seekers of the Storm released August 27, 2024, confirmed directly via Steam's own release-date field. The real 2025 expansion is Alloyed Collective, released November 18, 2025 (Switch following in Q1 2026, per official patch notes), confirmed via Steam's appdetails API and official patch notes.

The mix-up is understandable given the games' shared timeline. Seekers of the Storm launched into a rough reception, and a week later Hopoo Games' co-founders and several staff left to join Valve, per Game Developer. Gearbox, who took over post-launch support, ran a multi-phase "2.0" recovery effort through the rest of 2024 into 2025, revamping Seeker, False Son, and CHEF's kits along the way (confirmed via the official May 2025 developer diary). It is still the only expansion sitting at Mixed on Steam, and that long recovery arc kept "Seekers of the Storm" the more talked-about name well past its release window, which likely explains why it gets mistaken for the newer release.

Alloyed Collective, by contrast, launched clean and still sits at Very Positive on Steam. Confirmed contents beyond the bosses and items already covered: 2 new survivors (Operator, Drifter), 6 new enemies, a new elite type (Collective Elite), a new "Solus Family Event," 7 new drone types, 7 new stages plus 1 new loop variant (Iron Auroras), and 5 new interactables. The same update added Remote Operation, which lets a dead co-op player pilot an ally drone until revived, for every player whether or not they own the DLC.

Hallowed Concepts bosses (October 2026)

Hallowed Concepts released on Steam on October 8, 2026, at $14.99. Gearbox's launch notes promise "3 New Bosses" and name none of them. The community wiki has since filled the gap from the game files and lists five entries under the DLC: two Teleporter bosses and three special bosses. The counts don't line up because the wiki gives the Corroded Wurms their own entry, though they are only one phase of the Echo of Providence fight. We can't tell which three Gearbox counted, so all of them are below.

The two Teleporter bosses work like the old ones: each has a boss item, the Whispering Fragment for the Lynx Totem and the Mycelium Cap for Shruum, and each Uncommon reward has a 15% chance to become that item. Our item tier list ranks the boss items against the rest of the pool.

The other two you have to go looking for. A Shrine of Descent can spawn at a random spot when a stage starts, and activating it turns the next Teleporter event into the Soul-binding trial. Survive it and a Ritual Portal opens to the Soulbound Threshold. Inside, four arena challenges race a doom timer that starts at 210 seconds, and if it runs out everyone dies, revival items included. Clear all four and the Anima Harvester arrives.

The Echo of Providence sits one step further. Cast the N'tormat's Reincarnation ritual on the Soulbound Threshold altar after the Harvester falls, or at Prime Meridian, and you reach The Last Breath. Beat all four phases and each player gets an Echoing Essence: five items (one Legendary, two Hallowed, two Uncommon), of which you take two. We'd only attempt it on a run that already beats Mithrix comfortably, and in co-op we'd agree on it before the Shrine of Descent; our co-op guide covers how revives work in a squad.

Step-by-Step: prepare for a boss run

1. Confirm the route. Use the Stages Guide to identify the stage, loop, or hidden realm that leads to the encounter you are planning for.

2. Choose the survivor. The Survivors Guide helps match mobility, range, and defensive tools to the boss roster instead of treating every kit as interchangeable.

3. Plan item access. Check the Items and Artifacts Guide before enabling a run modifier, especially when a boss strategy depends on a specific tier or artifact effect.

4. Study the final fight. The Mithrix Guide covers the Commencement encounter, while the Interactables Guide explains the machines and shrines that shape a route before the teleporter event.

5. Plan the ritual fights. The Anima Harvester and the Echo of Providence only appear if you go looking, so decide before the run whether you're chasing a Shrine of Descent. The Hallowed Concepts survivors post covers the rest of the DLC.

Frequently Asked Questions

Who is the final boss in Risk of Rain 2? Mithrix, "King of Nothing," fought at Commencement. Beat him and escape the moon on the Rescue Ship to win the run. Looping happens earlier: align the Stage 5 Teleporter with the planet instead of the moon to go back to Stage 1.
