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.
this is all for fun, so here's how this build works. you use the lich bane to turn your giant ap into attack power. since soraka's star call has the exact cooldown as lich bane's unique passive, you can constantly drop giant damage on whoever your against. and whats an easer way to get stacks on majai's then sitting at base with soraka's ult and getting free assists because u healed your friends. so you just starcall, auto attack hit for giant damage and then do it again every 2 seconds. but this is just for fun, by no means do you ever play a real serious game using this build. but it is funny to see soraka hitting for 700+ damage auto attacking. well have fun farming all the gold needed to finish this build ;)
