Mobs

Health, drops and the three Forest Cave mobs behind spawn gates

Data updated 26 Oct 2026

Of the 157 non-boss mobs, 88 are hostile. 3 only enter a spawn table once you pass a days-played, armor or max-health mark, so a creature missing from your caves is usually waiting on your progress.

How Mobs Work

Difficulty

Health and damage both follow the world difficulty. Entries show casual through brutal side by side, so read the column for your own world.

Spawn Gates

Three things can hold a mob back: days played, armor and max health. Until you cross the mark it is not in the table, which is why early caves feel tame.
