Dynamic Difficulty

Dynamic Difficulty is a highly customizable mob leveling system, designed to address the precarious balancing act in adventure modpacks between player strength and mob strength.

Mobs are assigned a level based on factors like entity-specific starting levels, zone bonuses, and strength of nearby players. Everything is configurable!
Dynamic Difficulty was originally based on the Auto Leveling mod by Daripher,

Current Features:

Configure which attributes are modified per level, and their amount
Distance/depth/height-based leveling (via config, or per-dimension via datapack)
Entity-Type (and entity tag) setting overrides - override dimension-based leveling
Structure-based (and structure tag) level bonuses to all entities within structure(s)
Biome-based (and biome tag) level bonuses to all entities within biome(s)
Player-based level bonuses (See Compatibility section below)
Loot modifier/condition to inject loot into specific mob levels
Area Name and Level Title Text for leveled areas (Dimensions, Biomes, and Structures) upon entering
Rare, tiered potions and crystals that drop from leveled mobs, used to level up your own pets/other mobs
Displays level next to entity name, colored based on estimated difficulty relative to player
