Here is an interesting build that attempts to make a spellsword type of char that can do just about everything with some proficiency. I call her the "Divine Axe Finger Wriggler Please Don't Dispel Me"
Human Cleric 16 / Sorceror 17 / RDD 7
Starting Stats Str 10 Dex 16 Con 8 Int 8 Wis 15 Cha 16
Pros: High AC, High AB, decent damage, tons of buffs to choose from, tons of spells including bigby, premonition, isaac's greater missile storm, haste, improved invis, spell mantle, aura of vitality, divine power, and harm. Cons: Very low Hitpoints, fragile pre epic, susceptible to spells, weak when dispelled, 3 attacks instead of 4, low skill points, saves aren't great, and long long long buffing times.
fully buffed which doesn't last long here are the stats.. 42 AC +58 AB first attack 454 hps
buffed without divine shield and war mastery 32 AC +47 AB first attack
i think my aura of vitality wore off too at this point, but u get the basic idea of what she is like. BTW, I've read all these posts about divine power bug, and I tested it with only one divine power on and u get four attacks. So this isn't a munchkin build if you choose not to stack ur divine powers. Just don't do it!
