Mana Crystal+2poots>boots>Catalyst>Rod of Ages>Sorc Boots>Death Cap is the core build for Kass that I know of. You should have a fairly decent amount of mana, enough so you don't go without, and you will be tankier thanks to the extra health.

Worthwhile items to consider would be Morello's Evil Tome (CDR, Mana Regen, and a good amount of AP, Kass benefits from all of these), Abyssal Scepter, Zhonya's Hourglass (I would probably get this after deathcap if the game is going on that long, since you have to be in melee range most of the time you might find it useful), Void Staff (they will stack MR if they are smart),  Lich Bane, Banshee's Veil, the usual.
