Remove curse to lowered to 15 mana is a must, its way to expensive right now.
Divine fury needs to be improved, right now it does virtually nothing noticable.
Conscrete weapon should make your weapon glow white or something cool, and should have a longer duration. I think perhaps instead of targeting lowest resist it should lower the targets armour level base by -10 when it hits.
Also I think the 3 hit thing is a great idea, perhaps make it 5 hits or 30 seconds at high karma (instead of the 5 seconds or less it is now)
Holy light it a pretty good spell, though giving it a minimum damage of 10 would be a good idea, it only does about 7 damamge to people with good armour, thats just not enough
A few other spells perhaps:
Conscrete armour, 15 mana, lasts a minute at high karma, add's 5 to all resists at gm chiv, adds 2 to all resists at 70 chiv
Summon Avatar, requires high chivilry to cast (like divine sacrifice), is about as hard as a fire elle but instead of casting mage spells casts pally spells to help blues around it (eg, close wounds if they close, remove curse, and cleanse by fire), it could also cast holy light every now and again.
The drawback would be that it cannot attack blue players and/or perhaps other pallies with say above 80 chiv (or perhaps = or higher then the casters chiv skill)
Thats my two cents, what ya's think?
