Please read the first post again.
His point is still moot. It doesn't matter that it causes more dura loss. Why are you hitting a dead enemy anyway? When I know 3 hits kills a guy I don't swing 4 times. Hitting ANYTHING causes dura loss so you really should never hit something unless you absolutely have to do so. How much dura you lose from it is meaningless if you use your weapons intelligently to begin with.
So please read my post and understand I am not refuting his point. I am merely stating that it is meaningless because for it to even happen means you have to be swinging at things you don't need to be swinging at which you should already be trying to avoid doing.
Yeah, you're just being stubborn now.
I had my main two weapons break in the easiest boss fight (congregation) because I didn't know that corpses affected durability. The corpses were scattered around the main bosses, so I couldn't help but hit them. One swing through 5 corpses with my Smelter Sword (low durability already) was enough to massively chunk down the durability bar. Still won but had to equip a third weapon mid-battle.
Here's the thing - corpses in this game don't seem to have the physical properties that they did last game (no physics). As such, it's easy to assume that they are just there for added visual density. It's not obvious to assume that they would affect your weapons in the same way that a living enemy/wall would.
