XP: Attribute Core
by HER0XP
XP: Attribute Core is a Forge and NeoForge library that adds a modular set of RPG-style attributes, each with its own ID and current value, to Minecraft 1.20.1 and 1.21.1.
What it does
Attribute Core sorts its many custom RPG attributes into three groups, offensive, defensive and utility. Each attribute carries a unique ID under the attributecore namespace, so commands, datapacks and other mod integrations can refer to it directly. The attributes are meant to add depth to combat and progression, with bonuses such as physical damage percentage increasing damage output under pressure.
Players can view their active attributes in the included Attribute Display Window, which lists each attribute's name, ID and current value. The window opens with the K key by default. A Magic Find system injects extra loot from datapack-driven loot tables, and the mod exposes hooks and APIs that other mods and datapacks can build on. Configuration options let modpack creators and server owners balance how the attribute system behaves.
Installation requires AttributeFix. Epic RPG: Magic Find Loot and XP: Epic Damage Indicator are optional. Servers that run it need every player to install it too. Files are published for Forge and NeoForge, for 1.20.1 and 1.21.1, under All rights reserved, so the mod is not open source.
Key features
Offensive, defensive and utility attributes
Custom attributes span three groups, so a character can be built around damage output, survivability or support effects.
Attribute Display Window
A dedicated window shows each active attribute with its name, ID and current value, opened with the K key.
Datapack-driven Magic Find
Magic Find adds extra loot drawn from configured loot tables, which datapacks can change without code.
Hooks for other mods
APIs and hooks let other mods and datapacks read and extend the attribute system.

How it compares
Combat Balance is a client and server Forge and NeoForge mod under the MIT License, published for 1.20.1 – 1.21.1, that also adjusts combat. Random Attributes is server-side only, under All rights reserved, and covers the same 1.20.1 – 1.21.1 range, so players join without installing it. Attribute Modify is client and server, under All rights reserved, and reaches 1.20.1 – 1.21.11, which extends past this mod's range.
