StowableXP

StowableXP is a Minecraft server plugin that lets players store their XP safely inside bottles and books with a vanilla feel.
This plugin does its best to mimic the vanilla XP bottle, but instead you can store specific amounts of XP inside a bottle instead
of a random amount! You can even store your XP inside a Book if you prefer! And also, when you "redeem" the XP from a bottle
or book any item in the offhand or armor slots with mending will be mended accordingly as if you picked up the XP!
