FireLance said:In the case of Cleaving off an AOO, as I mentioned, the flavor issue is that an extra attack from an AOO feels like an extra AOO, and it seems odd to apply it to an opponent that did not provoke an AOO from you.
It's not an extra AoO. It's a cleave attack that you paid two feats in order to accomplish, or three if you have Great Cleave.
The price is adequate, and given that an opponent must actually be killed in order to enjoy the benefits of either two or three feats, placing additional constraints seems unnecessarily stingy to me.
Jhulae said:How I view the 'momentum' (and that isn't even in the description of the feat in the SRD) is the cleaver is 'psyched up' at having dropped an opponent, therefore pressing his attacks against another available opponent (one within threatened range) through superior training (via having the cleave feat). It's not the physical momentum of the weapon, but the momentum of combat.
Any description of how cleave works is equally valid, since the feat itself says nothing of how the cleave attack comes about. It simply lists the triggering circumstances and effects. It is reasonable, however, to assume that cutting an opponent in half is not a requirement, as some people seem to think, since piercing and bludgeoning weapons can be used with the feat.
