Natural DR and stoneskin

[shroudb]

let's say we have an eidolon with DR 5/good and the summonner casts stoneskin on it (dr 10/adamantine)

if the eidolon is hit with for 10damage with a non-evil, non-adamantine attack what happens to the hp counter of stoneskin?

does it depletes 10hp from the adamantine or does the first 5 points of damage get stopped from dr/evil and the rest 5 from stoneskin depleting only 5 points?

This is the way I look at it.

Stoneskin is a spell laid over the target creature. Natural DR is your skin.

Which do you think gets hit first?

well it's for a player of mine.

i don't really mind either way, he already abuses stoneskin to the max either way^^ (umding scrolls of bloodmoney) just wanted to see if for his setup getting the DR evolution is pointless or not.

I wouldnt say its pointless, he may not have time to cast the spell. It only lasts 10min a level so cant be cast to far ahead of time. Also it if the fight is a tough one the stoneskin could run out of hp absorption.

Only 1`DR will function against any incoming attack, and it's whichever one has the most effect. In this case the DR 10/Adamantine that is better at stopping incoming damage, so it is doing the gruntwork, and should expend 10hp from the reservoir for each attack.

I suppose it is more interesting if it was DR 10/Good though, in which case, I'd be inclined to rule in favor of the creature, that it would use the DR 10/Good "first" as being most advantageous for the character.

The answer is that Damage Reduction overlaps, it doesn't stack and it doesn't choose. Both DRs are struck at once, and whatever the least amount that gets through is the damage dealt.

For instance, you could have stoneskin (DR 10/adamantine, 10hp/level max) and defending bone (DR 5/bludgeoning, 5hp/level max). If struck by a slashing, non-adamantine weapon for 15 points, you would take 10 off the stone skin, 5 off the defending bone, and be dealt 5 damage.

Side note: DR/good requires a good weapon to bypass, not an evil one.
