MobTweaks Wiki

Listed as "Mob Controller" on Modrinth — same mod, different display name there because "MobTweaks" was already taken.

Granular, per-mob, per-ability behavior control for NeoForge 1.21.1 — replaces the all-or-nothing mobGriefing gamerule. No Cobblemon dependency, works in any modpack.

See the README for the full feature overview.

Getting started

1. Run /mobtweaks open (OP4 by default) to launch the GUI editor.
2. Pick a mob from the filterable list on the left.
3. Toggle its abilities (checkboxes), configure loot overrides, and set spawn restrictions (dimension/biome/light level) — every change autosaves instantly.
