Damage Reduction and Poison

[Irish Wet Dog]

I've tried to find the answer but I can't so I'll ask here.

Today there was a question on a fight involving a Bone Devil.

PC has had stoneskin cast on him.
So the PC has DR 10/Adamantium.

He gets hit with a Bone Devil's tail.
The tail does 9 damage.(The tail does 3d4+5 plus poison)

PC says that he shouldn't have to worry about the poison because the damage didn't overcome the DR. Basically he says that the stinger didn't get through because of the stoneskin spell since it didn't overcome the DR.

I felt like it was good argument so we rolled with it, but I still don't know if that is correct.

So, do you have to overcome the DR to inject a poison?

[Saltfish]

Bone Devil's poison is an injury poison so the Devil would need to deal damage through DR to inject the poison.

If it was a contact poison then it would be possible to get poisoned without actually getting injured first.

[Rikkan]

Whenever damage reduction completely negates the damage from an attack, it also negates most special effects that accompany the attack, such as injury poison, a monk's stunning, and injury-based disease.

Makes sense to me. Thanks alot Saltfish.

And Rikkan. Still wish I knew which book that sentence was in.
