Fey & Warlock DR

[Everol]

I was thinking about making a fey bloodline / warlock type character. I know most DR doesn't stack and I am guessing the Fey and natural warlock DR don't stack even though they are both /cold iron ? If so it would be pretty much useless besides the rp aspect to get the fey skin feat?

Molag__bal or Blackman D I think would know.
Try sending them a PM.

They do stack.
