If you are subdued while in rage, and rage wears off after it gave you like 16 additional hp, will you actually die?

FOIG!

No, really, I think you will, at least as long as the effect isn't cancelled by being subdued in the first place (that used to be the case).

No, you will just get up, rage wears off, and you get SD'd once more.

Thanks. Forgot to ask if the same thing happened in sparring mode?
