Does DR stack/overlap?

[shilsen]

What happens if a vampire (DR 10/silver and magic) casts stoneskin (DR 10/adamantine) on itself? If it is attacked by someone with an adamantine weapon, does it breach the effects of the stoneskin and cause dmg-10 due to the vampire's natural DR? And what happens if someone attacks with a mundane non-magical steel sword and rolls 15 pts of damage? Does the 15 pts become 5 pts of damage (10 being absorbed by the stoneskin) or none at all? Any help is appreciated.

DR does not stack, it overlaps and you apply the best one for a given situation.

Yes, it breaches the stoneskin but not the natural DR.

Look at DR like this.

When they say DR 10/magic and silver it means this.

DR 10/magic
DR 10/silver

(If you don't have a magical silver weapon, you don't breach DR)

Now add stoneskin DR 10/adamantine

Now if you don't have a magical silver-adamantine weapon, you can't breach the DR.

You have to beat ALL the DR types to not have your damage reduced.

So stoneskin becomes INCREDIBLY effective for that vampire. It's basically guarenteed to have DR 10 against everything.

Thanks. I predict that...(looks into the future)...my players will sooo hate you

From my reading of DR in the SRD you take the best of DR.

So in your example you have
10/magic
10/silver
10/adamantine

So if it gets attacked by a magic weapon it bypasses 10/magic but not the other 2 and reduces damage by 10.
If it is a silver weapon it will not bypass the other 2.

So as CalrinAlshaw said it would require a magical silver-adamantine weapon to beat this things DR.

I have never seen a weapon made of 2 special materials before so it would seems to always get DR 10.

What alshaw says HAS to be correct because otherwise using DR 10/magic or silver makes the vampire worse off than he was before... because now ppl can use adamant weapons too.

Seems too powerful though... maybe it works in parallel like folks have said?

EDIT: silly me. working in parallel is the same thing

Hi!

No, I don't think so: Dispel Magic...

Or just use magic so DR doesn't apply. And the nice thing about lower DR's is that while DR 10 makes it tough, a fighter or barbarian that averages 20 dmg on a hit will still average 10... which isn't too good, but they don't need to resort to just finding a place to sit down and watch the show like they did in 3.0 (assuming they couldn't bypass the DR)

This is a tricky word game that is made more difficult by the poor description.

If I was making a ruling on this
DR 10/Silver and magic -- The damage resistance has 2 weaknesses either a silver or a magic weapon can bypass it. Under the devils and deamons they have seperate resistances for good and somthing else. In that case bypassing one resistance would have no effect on the other. i.e. you need a "good" and an "iron" weapon.

In the wizard vampire case I would say a Magic Adamantium weapon would bypass everything. The other interpretation would make the vampire pretty much invulnerable since you can't have a Silver/Adamatium/Magic weapon. This makes him much more powerful than high level devils.

If either a Silver or a Magic weapon was needed to bypass the DR that would be DR 10/Silver or Magic. DR 10/Silver and Magic means the you need a weapon that is both Silver and Magic to bypass the DR.
