[Agema]

Summoning can be a big problem, it's not just gem wastage on elementals. I've noticed mages with death often just sit back and spam skeletons and soulless when they could be firing much, much more useful stuff. The summoned skeletons usually just lag behind the battleline and/or get stuck behind your other troops, and contribute little or nothing (except maybe some distraction for enemy mages with anti-undead spells).
