Patch Notes

v0.107.1 (June 19, 2026, stable/main branch): Aeonglass replaces Doormaker as the Act 3 boss, moveset and Wither/Withering Presence mechanics carried over from the beta that preceded this release. v0.108.0 (July 3, 2026, BETA ONLY): cosmetic only -- added Aeonglass boss animations and Wither card portrait art, no stat changes. v0.109.0 (July 17, 2026, BETA ONLY, not yet on the main branch): 'Ebb move damage decreased from 26(32) -> 22(26) to lower its front-loaded damage.' This nerf is NOT reflected in the stats above, which target the live stable v0.107.1 branch. v0.109.1 (July 25, 2026, BETA ONLY): localization hotfix only, no Aeonglass changes.
