Hang on, I thought the charge bonus was added to the normal melee damage to determine the actual damage of the attack. Isn't it?
It does, but the problem is that 2-Handers on the charge have such a high, (and AP), attack anyway that they rarerly fail to kill, so appart from the strikes first bit, (and I havn't done any testing on it, it's just random things i've noticed), it has no noticiable effect.

Yeah, as I said, I'd apply this only to 2h-swords, not to polearms.
Sorry, misunderstanding.

Yes, I know, but I'd like to...
Just wanted to make sure you knew, thats all.
