No Polymorph
A simple mod that grants permanent polymorph immunity from the very start of the run — no perk required.
What it does:
Blocks all 3 types of polymorph from affecting the player — sheep polymorph, random mob polymorph, and unstable/broken polymorph. When a polymorph is blocked, a visual effect and on-screen message will appear to confirm it.
How it works:
The mod applies the game's built-in polymorphable_NOT tag to the player on spawn, combined with a backup effect removal system to ensure no transformation slips through.
Compatibility:
Does not overwrite any base game files, so mod conflicts are unlikely.
