So I just started playing her, and I am not sure what to get on her, I have seen that generally you either go tear, or RoA and not both (unlike what you do on Kassadin). Since I just got her, I seem to just get tear and RoA and then Rylias, boots, void and deathcap.
But which is better for her and what is generally some solid items to get on Cass? Tear or RoA? spellvamp?
HELP ME OUT HEREER
