i asked this in another thread (in more detail) but what was the balancing decision behind making necromancy summons scale with summoning level instead of necro level?
increasing necromancy level doesn't make any of the necromancy spells more potent. it's only your character level + int + (interestingly) warfare for physical dmg spells. increasing necromancy only makes you heal more % when doing physical damage (perhaps because they wanted to make it different from the elemental damage schools)
