NBT XP Multiplier

NBT XP Multiplier

Direct NBT tag manipulation for experience_orb entities. Multiplies XP drops at the source without increasing entity count.

1. Trigger Edition (Singleplayer / Small SMPs)

Built for pure Survival/Hardcore. Players can configure the datapack dynamically without Cheats.

• Requirements: Minecraft 1.20.2+
• Permissions: Level 0 (No OP required).
• Performance: Minor tick overhead (listens for triggers in the tick loop).
• Set Multiplier: /trigger XPMultConfig set <1-10000> (Inputs are clamped to prevent NBT corruption)
• Toggle Boot Message: /trigger XPMultToggle

2. Function Edition (Large Servers / SMPs with Cheats)

Optimized for high-population servers. Strips all listener checks from tick.mcfunction to maximize TPS.

• Requirements: Minecraft 1.20.2+ (Utilizes function macros)
• Permissions: Level 2 (OP required to configure).
• Performance: Zero tick overhead (configuration functions run strictly on demand).
• Set Multiplier: /function xpmult:set {value: <1-10000>}
• Toggle Boot Message: /function xpmult:toggle_msg

Which version to choose?

Choose the version that matches your environment. Both share the same core NBT logic but differ in configuration handling.

Why use this?

• No Extra Entities: Multiplies the XP value directly at the source via NBT tags. It modifies the existing orb rather than spawning new ones.
• Skip the Grind: Maintain enchanting and Mending gear repairs through standard gameplay (mining, exploration, combat etc..) without the need to build ugly mob farms.
• Accelerated SMPs: Perfect for global server events (e.g., x5 XP weekends) without altering vanilla loot tables or mob spawning rates.
