Stacking DR

[Verzen]

How much DR can someone theoretically stack? And what build would this be?

[Mondoglimmer]

If I remember correctly, DR doesn't stack. I could be wrong, though.

[Nipin]

As Mondoglimmer said, most sources of DR don't stack in the normal sense of the term. For example, if a character had DR 10/magic from one source and DR 10/adamantine from another source, the net result would be DR 10 magic and adamantine/ So, instead of reducing damage twice by ten for a total of 20 DR it only reduces dmg by ten total and requires the opponent to overcome both types to overcome the DR. In a sense it is simpler this way, but DR is typically limited to < 20 which is negligible at higher levels. DR can be great for lower levels(when dmg per hit is small), but is very difficult to get at lower levels.

[Chemlak]

In general the most effective DR against a particular attack is the one you should use.

I'm not a build expert, so can't help there.

[Belafon]

If you're looking for DR/- the highest is probably a 20th level Invulnerable Rager barbarian who has taken the Increased Damage Reduction rage power three times.

DR 13/-

[Zwordsman]

additionally isn't there a feat that'll let you change over some sort of ac bonus for dr?
I wanna say.. it affects defensive fighting or something?

[Verzen]

I've heard of a build, can't find it atm, that is capable of getting DR up to 25 or some such. That's why I am asking.

Easy .
Add to the 13/- of the barbarian the following :
Combat expertise
Stalwart and improve.
You have DR 26/-

Stalwart max bonus is 10. You will have 23/-, but with dragon totem you coul reach 29/-
