Er, don't you mean Evo intead of Const? They're actually Evocation-3 and -4, respectively. While interesting, about the only thing I would research early in Evocation is to get Arcane Probing. I would have to evaluate whether or not the other spells were worth it, that early in the game.

How do you use the Seithkonur, if you do get that high, though? I find it hard to imagine you're going to want to fire Nether Bolts into a melee, considering the effects should they hit your giants. OTOH, I don't see how they would be effective as a 'solo' magical attack squad. Do you use Vinemen to protect them, or something?

Healing light is pretty nice on smaller numbers of high HP giants. As for nether darts, I don't find I lose many giants to it, because of their high hps. Later in the game, SC's like ice devils are not affected much. It's particularily potent against SC Users who back those troops up with archers and mages, as the seithkona will fire into the back lines. Combined with relief, this provides excellent spell backup.
