An item that blocks a pokemon from receiving EXP from battles.
Scenario: Let's say Im using a lvl. 71 to one hit a horde of Garbroudor so that a couple lvl. 16's using exp share can level up faster. In this case I'm not really worried about the lvl. 71 leveling up but his share would allow the lvl. 16's to level up much faster.
It can be called the Share Collar.
