I always wondered why, when dominions has a troop selection mecanism for rituals (see gift of reason), there are so few spells using it (compare with MoM or AoW where perma buffes on troops are a part of most winning strategies).

As recruitable troops can't be improved over time, this kind of school/powers would really give a new dimension to the game, if made to work better for troops buffing than for SCs. I would suggest for medium levels small permanent buffs (max +2 to a stat, +25% resist) but affecting several soldiers (of the same troop type / squad) at a time, so casting them on a lone commander wouldn't be cost efficient (eventually high level spells can include some more powerful but one unit only perma buffs).

Alteration and enchantment are already powerful schools, so I think a new one for this kind of spells would be a good idea. If transmutation is too close to alteration, perhaps it may be called the enhancement or sublimation school ie, a school using magic to develop/give natural abilities to mortals more than to transform them. With this idea of amplification of natural abilities, spells having effect in relation with the natural stats of the targets can also be imagined (ie : the same spell "improved dissimulation" increasing stealth for stealthy unit or giving a 25% air shield before they attack to other units ; "improved health" giving +1 to regeneration for units with a natural regen when it adds some hp to others, etc...).
