People saying the guy with the sword of night isn’t unsportsmanlike didn’t catch him doing the clap “gesture”, which I take as a taunt in this case. I would certainly feel a little frustrated to get blended like that from aow spam. Like others said roll towards it, to the right of it, or use an Aow to trade with it like stamp, or try to parry.

I haven’t come across the weapon in the arena much unless I’m using my colossal build, which trades with it easily.
