Personnally I'd like to see poison immune units also immune to the miasma effects, like they were in dom 2 iirc. It doesn't seem unthematic and would give C'tis a reliable way to protect indies mages (for 5 gems each), and to invaders a way to protect their valuable leaders.

But even in current state, I don't think C'tis to be underpowered. Marshmaster are really excellent for a mage recruitable *in any fort* (and as well C'tis has access to smithing priests everywhere) + don't forget the miasma income bonus.
