Not Updated For Current Season
The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
Welcome to the Galio AP guide!!!
Just a note this is a pure AP build and is still in the works sooo any ideas or suggestions plz let me know and i will work on them :)
As for summoner spells i general like exhaust just for the blind its nice to use when you have a strangler or when u want to blind that melee guy bashing you. Also with this build i find it nice to blind one target if you are rushing in to ult since it has a max hit ratio of 8 you dont need to take more hits than that. As for flash well i hope you know what is used for jumping in and jumping out haha.
As for runes you can pick whatever i kinda just put it together soo i will have to work on that a little more haha.
as for mastery's i find this one necessary because you want to have those abilities off cd as soon as possible so you can continue to kill those pesky other summoners also this will give you a little more Magic pen for some more dmg out put.
