I seem to recall seeing something about this before, but can't seem to find it...
so:
Chaosgarde: +2 dodge bonus
and the Chaosguard effect: (+2 deflection bonus to AC , +2 resistance bonus) vs. Chaotic enemies
The question: does the deflection bonus and resistance bonus stack with the prot 5 deflection item and the +5 resistance item as a special case, ignoring the normal stacking rules?
Again, seem to remember seeing this before, but can't confirm atm.
