It's a pokemon item that is used by a weaker pokemon to gain exp from a battle without having to even be in it. The OP would use it on their textbook to study and gain knowledge while sleeping
How have I never come across this in a Pokemon game?
or while lifting weights you can use a rare candy
I am detecting epic amounts of WIN here
i love this!
exp share? what in the world is that?
I pity you.
