and Friendly Fire is hilarious, if unoptimal.
You mean that spell that turns all rays (or any other ranged touch attack) back on the caster?
...yeah that's totally
suboptimalBut then really, this coming from (and I don't know about you personally) people that advocate getting rid of Necromancy if you are playing a high level wizard. Necromancy, which has one of the best defensive spells in the game.
How about...Anticipate Teleportation, Indomitability, Antimagic Field (if you plan on spell aiming), Starmantle, Ironguard,
Mindblank, Effulgent Epuration...to name a few.
And you already mentioned the Dispels, which are sometimes essential for defense as well.
Almost the entire school of Illusion is defeated by a single spell...yeah...and miss chance/AC are virtually irrelevant if you optimize correctly. Transmutation is better for spells like Celerity and Shapechange.
