Ignore Hardness on Natural Armor?

[RealMarkP]

Using an ability that ignores harness (ie. Pulverize), what effects does this have on natural armor (of say, a dragon)?

[Jackinthegreen]

None.  Natural armor and hardness have no relation to each other.  An ability that could ignore both would have to specifically say it could ignore both.

Hmm, yes. However, by the rules if you attempt to sunder an object that's held or worn, it uses the wielder's saves. But, it's still made of a material and the material has hardness. I'm just wondering if there is a difference between the stone that a golem is made of and a club that is being held?

[Jackinthegreen]

Natural armor is not hardness.  They are different rules concepts, regardless of what material or creature they're attached to.

Incidentally, clubs are understood to be wooden in D&D.
