Eleventh Hour Games posted the Last Epoch Hotfix 1.5.1.2 patch notes as a Steam community announcement on October 5, 2026. The version number marks the update as a hotfix for the action role-playing game Last Epoch. The patch notes contain bug fixes only, grouped under the Monolith, Dungeons, Weaver Tree, Skills, and Encounters headings. The update removes Monolith boss Yrun from spawning, fixes a dungeon retry lock, and resolves two Cinder Strike mana bugs. The update follows two prior releases from Eleventh Hour Games, including the Last Epoch 1.5.1 patch on October 2, 2026.
What the Hotfix Changed in Monoliths and Dungeons
Under the Monolith heading, Yrun is no longer able to spawn in Monoliths or in the Gauntlet of Strife. Under the Dungeons heading, the developers fixed an issue where players would get stuck after using a key to retry boss fights in dungeons.
These changes arrive after hotfix 1.5.1.1, which Eleventh Hour Games shipped on October 3, 2026. That update addressed Monolith boss Yrun and Rage of Morditas gauntlet issues.
Weaver Tree and Cinder Strike Mana Fixes
Under the Weaver Tree heading, the developers fixed corrupted copies from the Portents of Blood weaver node that were sometimes impossible to list. An important note from the studio explains that items generated before this fix can never be listed on the Bazaar and cannot be fixed to allow this. Items created from this node after the fix can be listed on the Bazaar without any issue.
Under the Skills heading, the first Cinder Strike bug involved the Flame Engineer node, which could still cause Explosive Traps to be created if the player had negative mana. The second Cinder Strike bug involved the Explosive Lash node, which would not consume mana if flasks are replaced by Explosive Traps via the Flame Engineer node.
Encounter Update for the Cenotaph of Worlds
Under the Encounters heading, the Ascendant Firstborn at the end of the Cenotaph of Worlds now properly summons Fateweaver Atropos at the beginning of its encounter. This change also fixes cases where the Ascendant Firstborn would unexpectedly become invincible forever at the beginning of its encounter.
