So, let's see. Cassiopeia is a continuous damage single target mage that makes use of DoT if I'm not drunk. With this in mind, here's my guess on a full build (no specifical order): I know, some explanations aren't even worth writing. I haven't put in the build because you already have 30% bonus AP from. I understand that it's always nice to have lots of AP, but now you have the chance of building Rylai+Liandry without losing the 30% bonus AP. Also, not sure if Rabadon's 30% stacks multiplicatively with the innate's 30%. Rabadon with that passive sounds like overkill to me. Also, with the mana restore on Twin Fang, I'm not sure if building mana will be strictly necessary.
 * : 10% CDR, synergy with Twin Fang.
 * : now more appropriate for a carry with its 100 AP, also the slow on is nice.
 * : enhances Cassiopeia's DoT, penetration and health are kinda nice, synergy with Rylai's.
 * : there is no mage on which I wouldn't get it, honestly.
 * : kinda necessary, I'd say.
 * : kinda necessary, I'd say.

You'll better take what I say with a grain of salt though, since I'm not really an expert. I may be saying a lot of BS as far as I know.
