If you deal nonlethal damage with a weapon that has an additional damage effect such as holy or flaming is the extra elemental damage also nonlethal? Or is it added on as normal damage after the fact?
For example, say you have a Monk or Brawler beating some guys poor face in with Pinning Knockout after pinning him and has an amulet of mighty fists lighting said fists on fire. Or something similar. Is it nonlethal fire? and is the 1d6 result doubled with the rest of the damage of the punch if it is not?
Or how about if you are using a whip or sap with elemental damage on it. Is that extra damage leather or nonlethal?
