The creatures of Wayward are separated into monsters and critters.

The corpses of most dead creatures can be carved using a sharp item, allowing the player to harvest resources.

The spawn rate of enemies is affected by the difficulty/reputation of the world, which is determined by the malignity and benignity as well as by time of day. Tougher creatures are more likely to spawn at night.

Caves will always feature the same creatures, regardless of reputation and during the night, if your reputation is below 0, some very dangerous creatures can spawn.
