Yeah i forgot to say, i use the quest to exchange my lower level Empower for Maximize. I only use Heighten for spells which have high resist in higher level dungeons, such as Charm Person, for example. I plan on hitting pretty high damage with my firewall but i would like to make it as solid as possible then add in tomes, thats partially why the intel is so high.
I would also like to know what about only having Fighter Attack Bonus II, vs III and IV.
Thus, if i were to change the build itself it wouldnt be to fighter monk paly, i dont want to drop down from my +16 BAB, 4 attacks per turn build to a +11 BAB, 3 attack per turn, so i would change it and just add cleric and keep it in +16. For example: 10 Fighter + 7 Cleric + 3 Wizard
