are both very powerful and very weak. Resist,spellbane, and truesight are great, but this dwarf has very little mana to go around. Plus, he can't use magical transportation or healers. If you land an energy drain or two and a plague (admittedly super hard against a dwarf), he's a dead man walking while go visit the Arkham healer enough times to kill him. Or, just wait out his resist.

On the other hand, curse/blind is basically a waste of mana against a villager.
