Understand Which Mobs Are Affected by This Mod
Affected Undead Types
This mod applies to all standard zombie variants: regular zombies, husks (desert zombies), drowned (aquatic zombies), and zombie villagers. All of these will pick up and eat raw villager meat from the ground and gain the associated buffs.
Custom Zombie Support
The mod also affects custom zombies added by other mods and data packs. If you're using modpacks with additional zombie types, most will likely inherit this meat-eating behavior, though compatibility depends on how those mobs are coded.
What Doesn't Eat Meat
Other undead like skeletons, creepers, and witches are not affected by this mod. Only zombie-type mobs will prioritize and consume villager meat. This makes zombie-specific defenses more important in your base design.
Implications for Your World
Understanding which mobs are threats helps you plan your defenses. Focus your protective efforts on areas where zombies, husks, and drowned can spawn. In biomes or dimensions where these mobs are rare, the threat level is naturally lower.
