What do masteries do again?
So far I got my skarner to 4. I been focusing his mastery pretty hard and i'm getting there to 5
Is 5 the max? Also what benefits do you get out of it again? I know there was this custom stuff your champ gets but how do you use them even if you get it?
So far I see this neat mastery tab on the loading page so that's pretty neat, but I heard there's alot more to it so I need to figure it out xD
