Your Defences:
AC if you have base (before magic) Constiution of 24 is:
53 just standing there
59 if you move 20 feet
57 if you charge at least 20 feet
if in a frenzy you get an additonal +8 to you AC your the Constitution Up.
Meaning on a charge you have a 65 AC.
Continual Blurr so 20% miss chance.

Improved Uncanny Dodge (Need to be at least a level 33 rogue to be flanked)
MindBlank (Almost Compleately negates 2 schools of Magic and foils quite a few Divinations)
