It seems a though accurate carnage is applying to the main weapon accuracy when I believe it shouldn't. Couldn't check if it actually applied to the carnage itself but the current effect is very overpowered. It seems to be affecting the battle axe, sabre, club, dagger, stiletto and pollaxe.
Upon further testing it looks like this is happening even in vanilla, I thought about not posting this here but as it's one of the passives modified by the mod I might as well mention it. Couldn't find anything about this in a quick search, is it bugged or am I not seeing something here?
