OK, here is the situation:
A monster has DR 15/Cold Iron. A 12th level caster places stoneskin on this monster, giving it DR 10/Adamantite with 120 stoneskin hitpoints. A fighter attacking the monster with the Penetrating Strike using a +2 Mithral Elven Curve Blade.
How is this attack resolved? DR generally doesn't stack, only using the higher value. However, penetrating strike would ignore the first 5 points of DR. The weapon is neither Cold Iron or Adamantite, or carrying a +3 or greater enhancement bonus. So the DR 15/Cold Iron would reduce the damage from this Curveblade by 10.
Would the Stoneskin hitpoints not ever lose any value since the DR/15 Cold Iron is the better DR? Or would penetrating strike also effect the stoneskin DR, causing the Stoneskin to only absorb 5 instead of 10 hitpoints? Or would the DR/15 Cold Iron still take effect AND the stoneskin would absorb 10 hitpoints per hit?
This strikes me as a fairly unique situation, but I'm interested to know how stoneskin behaves when cast on a target that has a DR greater than 10.
Any input is greatly appreciated.
