Fighting alone with Orc race and Doppleganger

[MunchkinMan]

1) The Orc actually says that ability kicks in if the Orc wins by more than 10, which means you must have a combat strength that is 11 or more than the Monster side.

2) Doppelganger is an Item, not a helper, so the Orc is still fighting alone.

So, not having the final numbers, I can't give an absolute confirmation, but if the win was by 11 (not 10) or more, than the Orc earned two levels for that combat.
