AttributeCore is a library mod focused on RPG-style attributes and combat effects for Minecraft.

It does not add standalone gameplay content, items, or progression on its own. Instead, it provides a shared foundation that other mods can use to build RPG systems, combat mechanics, gear scaling, pets, aggro, healing, and advanced attribute-driven features.

AttributeCore provides a large set of custom RPG attributes, grouped into offensive, defensive and utility categories:

Melee Dmg

Library / API Focus

AttributeCore is intended to be used as a library/core dependency by:

RPG and ARPG-style mods
Custom gear and stat frameworks
Class / build systems
Boss and dungeon content
Modpacks with heavy combat scaling and progression

On its own, AttributeCore does not try to be a full content mod. It provides the attributes, effects and hooks that other mods and datapacks can build upon.
