You still kinda need RoA unless you like building Rylai with it's terrible recipe and build path. RoA gives both HP and Mana which helps with his scaling mana cost on use Ult and scales over time, added to the fact that the sustain it gives thanks to Catalyst makes it a great item on him. If you really enjoy having CDR on him, why not use Scaling CDR Runes on him? 15% Reduced Magic Damage on top of a Magic Damage Shield on Null Sphere is pretty much all you need in terms of Defense against Magic Damage. You can also get Morello's since I don't think Athene's is really good on him anyways. Catalyst at least gives you defensive stats while you have the item, Chalice just gives you MR and Mana Regen which aren't really good on Kass.

Though I do agree is Ultimate does feel underwhelming from a Damage point. At least compensating the base a little bit might sufice but still.
