[Wick]

One thing that distinguishes Breath of Winter (and Soul Vortex) from Fireshield is that they are synergistic with Astral Shield or Eye Shields. The shield renders the attackers harmless while the aura disposes of them.

One buff that didn't make the list is Holy Avenger. It's a Holy 4 spell that does unspecified (as Smite?) damage to anyone that hurts the caster. I don't feel comfortable with it since it's only useful after you get hurt. It might combine well with Mistform but not with the Mirror Image and high defense that usually go with Mistform.
