double-xp_bottle
by ModMastarZ
Experience Bottles dropped by double-xp_bottle grant twice the normal experience, a Fabric change for servers that want faster levelling.
What it does
When a thrown Experience Bottle breaks, the player receives double the experience it would normally give. The change applies only to that bottle type, so other sources of experience keep their vanilla amounts. Fabric API is required, and the mod is built on the Fabric Loader.
The mod is a small Fabric addition for servers. Its only effect is the doubled reward, and its configuration must be set before it behaves as intended. Because the environment is server-side only, players join without installing anything.
Files are published for 1.21.1 and 1.21.3, with 1.0.0 for 1.21.3 as the latest build, first released on 2026-09-02. The license is All rights reserved, so the code is not open source; the author asks users to read the included license before using or redistributing it.
