Would DR or Invulnerable Rager DR against non-lethal damage stop damage from a "cord of stubborn resolve"?
I know that DR normally doesn't affect spells or abilities unless it has an obvious statement. As an example, DR would work against "3d6 points of bludgeoning damage" from the spell ice storm.
