AttributeModify - Flexible Item Attribute Modification

AttributeModify opens up limitless possibilities for customizing item attributes in Minecraft. With it, you gain complete control over attributes of both standard and modded items, including integration with Curios API.

Key Features

• Works with any items: vanilla and from other mods
• Full compatibility with Curios API (optional)
• Smart attribute modification system
• Singleplayer and multiplayer support
• Hot-reload datapack functionality
• Multiple attributes per item
• No additional dependencies required
• Clean JSON datapack format

How It Works

AttributeModify allows applying three types of operations to attributes:

• Addition - adds value to the base attribute
• Multiply Base - multiplies base attribute by (1 + value)
• Multiply Total - multiplies final value by (1 + value)

  "minecraft:diamond_sword": {
