XP: Attribute Core

Attribute Core is a modular RPG-style attribute system that adds a wide variety of custom attributes, giving players more depth and challenge in gameplay.

The mod introduces RPG-like attributes and complementary mechanics to expand progression. It also provides configuration options so modpack creators can balance how attributes and systems behave.

Attribute Core includes its own Attribute Display Window, where players can view their active attributes, attribute IDs and current values. This window opens by default by pressing the K key.

Core Features

Attribute Core focuses on providing:

• A large set of custom attributes, including offensive, defensive and utility attributes.
• A dedicated Attribute Display Window, opened by default with the K key.
• The name, ID and current value of every active attribute displayed in the attribute window.
• Unique attribute IDs that make every attribute easier to identify and use in commands, datapacks and mod integrations.
• A Magic Find system that injects extra loot into configured tables (datapack-driven).
• Hooks and APIs so other mods and datapacks can build on top of it.
• Configuration options so modpack creators and server owners can balance the system.

On its own, Attribute Core does not try to be a full content mod. It provides the attributes, systems and hooks that other mods and modpacks can use.
