Chaos Zero Nightmare - Sereniel (Defect Skin)

Chaos Zero Nightmare - Sereniel

Defect Skin for Slay the Spire 2 v0.5.4-beta

Sereniel replaces The Defect's visuals, voice, and combat presentation. Gameplay and balance stay vanilla.

IMPORTANT: Beta Branch Only

• This mod supports Slay the Spire 2 Beta v0.111.0.
• It does NOT work on the v0.107.1 official (Major) branch. Running it there will break animations, effects, or startup.
• There is currently no official-branch build. Switch your game to the Beta branch before using this skin.

Version / Branch

• This file is v0.5.4-beta for Slay the Spire 2 Beta v0.111.0.
• The beta and non-beta branches use different animation interfaces, so a beta-only skin cannot run on the official branch.

Settings and Performance

• Settings are inside the in-game CZN Mod Config page. ModConfig is not required.
• Use Combat Presentation Mode: Fast or disable Card Play Cut-in for faster pacing.
• For lower visual load, disable extra particles or global combat effects.
• If the game feels unstable with high-effect skins, try a 60 FPS cap first. You can also test --rendering-driver opengl3as a Steam launch option.
• First-use animation stutter usually means assets are entering memory cache and may be smoother after the first playback.

Multiplayer - teammate presentation: the in-game CZN Mod Config > Teammate Presentation page controls whether teammates use character-mod presentation, plus their full-screen attacks, attack timing, combat effects, and effect sounds. If combat stutters with several teammates, turn the full-screen options off first.



Rendering driver: if the game is unstable with high-effect skins, set
--rendering-driver opengl3in Steam - right-click Slay the Spire 2 > Properties > General > Launch Options.
