Differences between DR / x and DR / x and y

[Tassel]

I just want to question if it is said that a monster, like lycantropes have DR/silver and vampires have DR/Silver and magic.

Which DR is better, does it mean that you can bypass both with a silver/mithral weapon, or to bypass vampires DR u need a magical silver/mithral weapon??

My players said that only a silver weapon is needed. But i have been checking and the more CR, more common is to have DR/x and y.

It could be the same with DR/adamantine and DR/andamantine and magic

Thank you very much. I expect i have explained myself.

DR x/Silver and Magic means the weapon needs to be both Silver *and* Magic to bypass DR.

Compare the Vampire: DR 10/magic and silver
with the Kyton: DR 5/silver or good

Your players are wrong.

Just thank you. I tried to find and example of it but i didn´t find one. I thought just the same. I will try t kill them with a vampire today. Let´s see how they manage it.

Really thank you for answering so fast

As a follow-up, note that a +3 or higher weapon counts as silver for the purpose of overcoming damage reduction, so in that instance you would not need the weapon to be silver.

A +1 undead bane weapon would also qualify as when used against it's bane target it's effectively +3.

Yeah, that ought to do it.

Special-abilities, You'll need to search for "overcoming damage reduction", for a specific place to find the rule that blahpers was talking about. (or page 562 of the core rulebook).
