18.5 follows up on 18.4: Azir and Kha'Zix go down while Soraka, Morgana, Taric and AP Master Yi open up other AP lines, and Tristana, Caitlyn and Sivir lead the AD buffs. Rapidfire, Riftbeast (7), Blackthorn (6), Elderwood (9) and Flora Fatalis are toned down, Fae heals more, and role Wisps now check your last combat instead of the board.
