Hostile Climbers
Allows other enemy mobs to climb walls just like spiders.
About this Mod
Other mobs (zombies, skeletons, silverfish, etc.) can now climb walls, making them more dangerous. Creepers can't, because they are already scary enough.
Default config:
"enabled": true,
// Fall damage multiplier for mobs. 0.5 = half, 1.0 = normal, 0.0 = none.
"fallDamageMultiplier": 1.0,
// Mobs listed here are allowed to climb walls.
// Add modded mobs using their registry ID, e.g. "mymod:custom_zombie".
