Xerath is one of those kind of "what the ****" champs, and what i mean by that is, when your just kinda doing your thing laning and all of a sudden your stunned and being destroyed by something you cant see. I mean its just plain disconcerting to be slain by something you cant see. But in all seriousness folks Xerath is a long rage Ap burst mage, and besides that doesn't have very many tricks, so be smart use the range and all things will be yours in time. One other thing i wanted to mention is the spell vamp, i havent seen alot of people use it and it realy helps alot cause Xerath's main farming ability is a huge aoe nuke and the combination of the two makes make your sustainability go through the roof.
