why not take away the proc off of teemo shrooms?

I dont see where it says it procs items. I assume you mean specifically though, and removing it isn't needed. The big thing is that his shrooms are basically undetectable, last 1/3 of the game, and do high damage. Good shroom usage can just wreck the enemy's ability to even try to play on one side of the map. I honestly think teemo's shrooms should have a 3-at-once limit as well as a 3-minute time limit. It'd be okay the stupidly high damage it does if it werent covering half the map.

i mean like ryials also
