XP Theory

Living entities gain experience systems of their own. A mob can absorb experience, which raises its health and size, and some mobs drop the experience they have stored when they die. The mod also adds an Enchanter, an illager that spawns in Mansions and in high-tier raids. Enchanters apply mob enchantments, and all mobs that share the same target Enchanter receive the same enchantments. Mob enchantments also reach the mob and the player, so the effect is not limited to the mob alone.

Enhancing Books apply enchantments to mobs, and Cleansing Books remove them. Some mobs can also become Ancient Mobs, which are rare at spawn. Ancient mobs yield more experience and carry high enchantments, shown by a golden glint. XP Theory runs on client and server, so the server and every player need it. Files exist for Forge only, for 1.20.1, with 1.0.1.1 as the latest file. The mod is published under All rights reserved. It works with MCDungeons mobs.
