So I went through and created spell turrets for each level that I thought were the best. Treantmonk's guides to being a GOD helped enormously.
http://brilliantgameologists.com/boards/index.php?topic=394.0As you can see, I pulled the best spells listed there some with their descriptions to make things a little easier. Also, the spells listed under Alt: are spells that I think would be pretty good if you don't like the one's listed. Note: When I made these, I just listed the spells down in no particular order. To me, getting the right schools was more important.
I'm not sure if spell turrets ignore components, if so then a host of spells that were not worthy enough before would come into play. If anyone has cheesy spells (especially from Faerun) then please post 'em up!
All 4 spells must be the same level, from the same list and from different schoolsspell turrent wizard -
level 11 - Protection from Evil - Abjuration
2 - Ray of Enfeeblement - Necromancy
3 - Grease - Conjuration
4 - Ray of Clumsiness (SpC - Transmutation) - It's Ray of Enfeeblement, except instead of weakening offense, it hurts their defense. Really nice spell, easily lowering AC and Reflex saves. Kill those pesky Rogues with this.
