good ideas except for the fact of some of the names and stats such as ocean lord (too close to storm lord) and fire seraph doesn't really sound all that interesting, and also the death stats should deal somewhere between 750 - 800 damage, but other than that good idea.
whats up with all the lords? sea lord, lion lord... more creative names would be nice I: and Storm spell should NOT reach above 1000... by doing that Leviathan power is pretty week... look at previous spells, it should be 820-930 or so
First of all, these are great ideas. It looks like you took the time to think about each school and tried to maintain the balance between them.
However, I think some tweaking may need to be done.
Storm:
I agree with a previous post, the damage should be lowered as this makes Leviathan pointless.
Life:
This spell seems too powerful. A 30% Balance Blade (or Dragon Blade) to all allies? Maybe adding a 20% Hex to all enemies? Perhaps heal all allies and attack all bad guys?
Death:
I agree, this spell is too weak. Keep in mind any spell that drains health is not an attack spell but rather a drain spell. So augments like Strong or Monstrous will not work on it. I think upping the damage, removing the drain should fix the problem. Maybe make the spell Zombie Horde as the necromancer unleashes his/her undead army on their enemies :)
Balance:
This is just a weak version of Efreet. Suggest either more damage or another stasis effect like, stun. Or, put a range on the damage, have it attack all enemies and decrease the penalty from -80% to -50%.
Overall, these are great ideas. I hope KI is listening!
