Black Knife also got improved in this patch for its Destined Death effect, also lasting a lot longer in Elden Ring Runes the same way, but that's the only change. Now in a previous patch, the Ash of War was made a lot quicker and it does have some hyper armor on it, so the Ash of War on this weapon is one of the best in the game because you get the deaths and death effect you get the damage and you get damage over time, you can simply spam this Ash of War and do really well or you could pair it up with another black knife and do loads of power stands striking. This is the best dagger that you can use in the game especially for Faith undeniably.
As a curved sword in power sense, it has an incredible moveset where you can attack super quick and therefore get loads of DPS. As a fire and physical weapon, it's super buffable so with all those hits hitting a lot you can make them do deadly damage.
The Ash of War is an incredible combo tool or trading tool making it really effective in PvP where you can just constantly barrage your opponent with attacks and then as soon as it's finally their turn Ash of cheap Elden Ring Items War spin into them and spread lava everywhere. Of course there are so many sections of PVE where fire is super effective and therefore this weapon is just a machine and it looks cool too.
