ToME: the Tales of Maj'Eyal

It sounds strange, but would this be feasible with the new locked spell tree in Embers and Staff Mastery? Would it almost require a Cornac?

A build like this would probably require ditching a lot of Strength (if not all of it) and therefore Breaths outside of Necromantic wouldn't be as great of a selection, not even Bellowing Roar, but there are plenty of other options available in Wyrmic's abilities.

I'm not sure you'd *have* to go with Cornac, as you'd save a lot of points by not going Anti-Magic anyway. Either Shalore or Ogre might work. They'd want to unlock Undead at level 10 and wait until later to unlock Higher Draconic.

Does Necrotic Breath benefit from Wyrmic Guile?
