This needs clarifying.Herzog said:Several AC enhancing class abilities (like Dex bonus to AC for monk and ninja) are also negated when losing your dex bonus to AC.
Dodge is one, yeah. There are many. Canny Defense -- Int bonus to AC, from Duelist or Swashbuckler -- is another.

I just can't remember which one it is.
