This is NOT a spigot plugin, It's an add-on to the AGMCore plugin.
To install this move the file to "plugins/AGMCore/Extensions"

This is is for AGMCore 3.3.1 or newer.

Sometimes losing the 314 levels of EXP to a sneaky Creeper is frustrating... Isn't it? With this addon, you can use glass bottles on an enchanting table to drain your EXP into them for later use.
We do not guarantee your survival during the extraction.
