Thank you very much for the information.

I'm not too sure about that ruling regarding Battle Fury. The power isn't very optional in terms of how it'a utilized.

This is wrong. "May" is the optional one, "can" means must.
Possessing Battle Fury means that the power can be OW'd... that's the only real difference between those powers.

That's wierd. "Can" and "possess" have the same meaning. But I read the Rule book and it is so. My mistake that I forgot HC has it's own set of language. Thanks for the correction.

Once you are within 3 of First Born you have battle fury. You cannot chose to not have it. If you somehow can get a friendly that can outwit you can do so. Once you enter 3 squares you get it. So if you running shot into it POOF attack gone. Battle Fury is a power that is always active. You cannot just CHOSE it. Posses keyword simply means it can be outwited

For those wondering, it is under "Use and Possess" on page 18 of the Rulebook, second paragraph: "A character uses a power if a special power or an ability states that they “can use” or “uses” that power."
