Stacking dr

[Relenthe]

I'm just cuirious what kind of dr stacks

Let's say you had a wf barbarian warchanter

3 inherent barbarian dr
5 warchanter dr
1 dr from improved at dr feat
2 dr from at improved wf enhancement
2 dr from improved barbarian dr enhancement
5 dr from the von trinket
2 dr from adamantine body
What would his dr be, and where would it come from
Also anything I missed or had wrong?

It wouldn't be much... 7 maybe?

Warchanter DR won't stack with the inherent DR nor the enhancements.

Not sure if WF DR stacks with barbarian DR, I'm guessing it does.

Trinket wouldn't stack with barb DR, nor would the adamantine body (pretty sure on this, as armor with DR doesn't stack with barb DR).

So... 3 inherent, 2 enhancement, 2 wf enhancement... 7?

Passive DR doesn't stack with active DR. And it's like for like only. I'm not sure what the necklace does or what it's DR type is but 9 times outta 10 it won't stack.

5 dr it looks like to me, meaning just sing Iron Chant and skip the rest.

Addy armor on a barbarian doesnt stack with his natural dr. I guess dr never stacks... although enhancement effects tend to stack in other situations.
