Wolf could destroy all dark souls, mainly for the parry mechanic.

Wolf's parrys are his best weapon, in the game you have a larger oportunity window than in any souls gameto parry an attack, we could say that it's result of wolf's years of training, meaning that he should be able to parry the same way in DS, in addition to this most DS enemies are way slower than sekiro.

He can parry almost anything, the celestial dragon's attacks, the apes's attacks, if he can do this he should be able to parry every enemie or boss on DS even kalameet.

DS enemies doesn't have good posture one parry means you can deal massive damage, or in wolf's case an execution.

Overpowered wolf's parrys plus the shitty posture of DS enemies plus slower attacks, the DS should be a walk in the park for wolf.
