Play agressive, ignite and dot with explosive shot everything that moves. Buy items in that order i show, it will first give u a nice boost to you'r damage, and after buying archangels stuff also strong boost to AP- and bot will still grow, with next staff. Mostly i end with 300 dmg bonus too ulti, and mele atacks for 300 each. I won'y write how to play her, cuz u probably already did (new players start witch top rated mega builds) so just try it, and if it works for u as good as for me, vote for this build
