Clipper is correct, but let me expand on the Orc's epic ability: You're getting rid of a Monster immediately, without anyone being able to stop you from doing it. You have to sacrifice something for that. Now, bear in mind that's a choice, and if you want to shoot for the extra level, you can try, but now the other players can modify the Monster so you might not be able to get that extra level.

And, on the Orc's ability: To get the extra Level requires an Orc to be winning by more than 10, not winning by 10 or more. That means that you need to beat the Monster side combat strength by 11 or more to get the extra level. Finally, you have to beat the Monster side by 11 or more to get the extra level, not each Monster individually, so it's only ever going to be one extra level.
