We noted previously that in battles that you can win by just killing one guy, you get marginally more exp if you bother to kill everyone. I just had the thought that you didn't go out of your way to make it so, but instead it is the bonus exp characters get for killing blows that does it. I thought this bonus exp meant they got a larger share of the exp, but I tested just now on the starting orcs, and this bonus exp seems to not be a redistribution of the points, but a pure bonus. That means each time we don't actively finish them, we lose out on exp - very marginal amounts though. For anyone wondering what "actively finishing" means... nobody gets kill credit if an enemy dies to a DoT; the game does not seem to register the source of DoT's.
So yeah for anyone looking to maximize exp gains... don't let DoT's finish your mobs
Late edit: Okay, Bramble Coat on enemies. That it triggers twice from a dual wield attack, I suppose that's okay. That it takes away 10% health instead of 5%? Not sure... but it's still another case of I'm winning and I don't need buffs. But I'm saying 10% per hit, so 20% for a DW attack. Very owie.
If at first try it doesn't explode, it ain't Jack who wrote the code.
