DR and Antimagic

[Dragon Mage]

I rememeber reading somewhere on how Antimagic effected damage reduction, but I can't seem to find it now. Is DR a supernatural ability and therefore is suppressed by antimagic? Can someone point me to rules covering this in the core books?

 

[Kae'Yoss]

Some types are extraordinary, others are supernatural.

If I recall correctly, Magic, Epic, and (Alignment) are Su, while (Material) and (Nothing) are Ex.

 

[NexH]

Some types are extraordinary, others are supernatural.

Indeed. But Magic, Epic, (Aligment), and most (Material) are Su, while /-, adamantine, and weapon type (Slashing, piercing, bludgeoning) are Ex

I remembered it was something along these lines.

Yes, can someone please give me the source. Thanks

I always thought all Special Material DR's were [Ex].. To join the chorus, I'd like to see the source, too.

This is addressed (partially) in the Errata for the Monster Manual:

Damage Reduction
Damage Reduction is either extraordinary (Ex) or supernatural (Su). Use the following guidelines if it is not specified.

• DR X/slashing, piercing, or bludgeoning should be (Ex)
• DR X/adamantine should be (Ex)
• DR X/-- should be (Ex)
• DR X/silver or cold iron should be (Su)
• DR X/magic should be (Su)
• DR X/chaotic, lawful, holy, or unholy should be (Su)
​

It doesn't give any guidance on how they came up with these or what to do about other forms of damage reduction, though. For example, is DR X/adamantine and magic (Su) or (Ex)?

The closest thing I can find is the FAQ, which states that DR X/magic and X/alignment are supernatural, and all others (X/damage type, X/material, and X/-) are extraordinary. I would guess that they include X/epic in X/magic.

 

[Rkhet]

what happens when the DR is, for example, X/Magic and Silver?
