masteries with galio?

Go all the way up the tank tree . AP tree doesn't work well on Galio because you not gona be able to tank in lane or in teamfight .

Galio is melee so make sure you grab 2% damage increase and 2 damage reduction from champions .

Also keep in mind that just because you playing Galio dosen't mean that you won't need any armor . You still have to build both armor and magic resist or ad carries with f you up .
