Custom Entity Leveling
by mrqx0195
Custom Entity Leveling lets non-player mobs spawn at different levels, with each level granting its own enhancements, including attribute boosts and status effects.
What it does
Non-player mobs can spawn with a level attached, and every level adds its own set of enhancements. Those enhancements can include attribute boosts and status effects, in the manner of elite monsters. Leveled mobs drop additional loot when they are defeated, so a fight with a higher-level enemy pays off.
The mod ships with no default behavior: spawn chances, level tiers and the enhancements they grant are set through config files. Configuration guidance is kept on the GitHub Wiki. Prickle is required and must be installed alongside the mod. Custom Entity Leveling runs on the server side, so players connecting with a vanilla client need nothing extra unless another mod they use requires it, and the core features work for vanilla clients.
The mod is published for NeoForge on 1.21.1 only, with release 1.1.0 dated 2025-07-25 as the latest file. It was first published on 2025-07-22. The code is released under the MIT License and is open source, so modpacks and servers may include it as long as they follow that license. Developed for NeoForge's 2025 Serverside Summer event.
