Hibernian Workshop published the October 2026 patch notes for Astral Ascent on October 11, rolling hotfixes 2.7.1 through 2.7.6 into one Steam news update. Astral Ascent is a roguelite action platformer from Hibernian Workshop, and readers can find more roguelite coverage in our Kernel Hearts launch story.
Clair Obscur: Expedition 33 Crossover Room
The patch adds a new Room choice based on the universe of Clair Obscur: Expedition 33. After a player clears their first run, the room can appear in all later runs. Once per run, at the 9th room of a random world, players get an alternate choice to Andromeda’s Bar. Taking the challenge starts a boss fight against a random boss from the Clair Obscur: Expedition 33 universe.
The possible bosses are the Mimes, Petank, and Golgra. The Mimes appear as a pair and must be defeated at the same time, otherwise the surviving one retreats to heal. Petank uses tricky moves that switch between offensive and defensive patterns. Golgra uses irregular moves, Gestrals in the arena assist her, and she becomes aggressive at 50% HP.
After the boss fight, players teleport to The Campfire. There they can buy Healing Shards, upgrade an Aura, hug Esquie for emotional support, and choose one of the Clair Obscur: Expedition 33 heroes. Three of the six heroes are offered per run. Because the crossover brings Clair Obscur: Expedition 33 content into Astral Ascent, players can consult our Clair Obscur: Expedition 33 builds guide for wider character context.
Clair Obscur: Expedition 33 Hero Mechanics
Gustave heals, boosts attack, strikes alongside you, and charges a finisher. Maelle shifts stance with your HP for a payoff attack. Sciel draws cards: Moon gives mana, Sun gives direct strikes, and Twilight gives a big hit. Lune casts elemental spells that build to a finisher. Verso’s rank rises on hit and drops on damage taken for a massive attack bonus. Monoco draws a random card that summons a monster.
Hotfix Fixes and Co-op Corrections
The Clair Obscur: Expedition 33 DLC was missing from the new menu, and hotfix 2.7.1 fixed it. The patch also fixes a large number of co-op issues where Player 2 effects were incorrectly spawning on or attributed to Player 1. Those effects include spirit swords, sphere shields, light swords, Ayla knives, flying slimes, and signature spell cooldowns and perks that used Player 1 stats instead of Player 2 stats.
Other fixes address a softlock when entering the Petank room with ordan’s fury, the Path Liberator telescope only working the first time, and co-op invincibility gaps at the end of boss fights and after Andromeda’s Trials. Both players are now invincible in those situations.
