... I saw this thread title and laughed ... loudly.
Divine Mind
5 , ya rilly with the Creation mantle
pops out 1 level 4 AC as a standard action (acf)
pops out 1 level 3 AC as a standard action (acf)
All have the 2 stack AC CPsi modifier thingy, that can attack first
and then blow up the next round with type-less damage.
1 or 2 attacks hit, and then the bang happens.
pops out a level 2 AC as a full action, on 2 encounters.
After doing that, it's a bad Divine Mind vs. a whatever Fighter.
My money is on the Fighter at that point.
So Divine Mind for 4 encounters, but not for the 5th and on.
Something that can ping out more and better ACs , is easy peasy.
EDIT --- Divine Mind only has a chance if he can fight the Fighter too.
