I wouldn't run more than 2 ashiok, his ability doesn't help consuming aberration, which I'd -2 and run 2 nighthowlers instead. A nighthowler bestowed on a consuming aberration is nice. Aqueous form for unlockable. I'd get some breaking, mind grind, tome scour, balustrade spy, and Mirko Vosk and Lazav can help a lot.
