Project MMO XP Bottles

Each bottle grants a fixed amount of experience: a Common bottle gives 500 XP, a Rare bottle 3,500 XP and an Epic bottle 9,000 XP. Every bottle also carries a beneficial effect tied to a skill of Project MMO, so the bottle supports the chosen discipline rather than only adding experience. Haste speeds up mining, Strength helps in combat, Luck raises the odds of rare drops and improves fishing, Regeneration keeps a player healthy during long fights, Speed helps travel, Night Vision lights up dark areas, and Water Breathing allows exploring underwater.

The bottles are built for Project MMO progression, where they add a shortcut to leveling. The mod is a Forge build for 1.20.1 only, and it runs on client and server, so the server and every player need it. It requires Project MMO, which must be installed alongside it. The author notes an option for servers with shops that sell XP through this add-on, and the author maintains public links to the source code, issue tracker and wiki.
