Weak. Just use the Lothric Knight Greatsword. It has Lightning Damage and can still be Infused AND buffed. I really see no reason to use this other than the better fashion and better moveset.

I'll be honest, everybody says, "This weapons sucks" or "this weapon is just mediocre" but I used it on a SL 200 character with around 90 STR and ~60 DEX and it devastates health bars while simultaneously deleting what broken remnants of poise are left on players hit by it. if you don't have the patience to lvl this weapon and your stats with it, but you have enough time to whine about how bad it is, just don't use it then and pretend it doesn't exist. Point is just stop complaining and use it right, and if you can't, don't use it.
