I personally think that 1 of these 3 could be the most useless.

1. Spirit Curse: it costs a death gem to curse while there are other spells that cost no gems.
2 .Bleed: have never been able to use effectively, when with lots of casters.
3.Corpse Man Construction: even with one of the magic items hat increase the amount of corpse men to make, I still find them a waste of air gems.
