The spirit ashes aren't very strong, however. The wolf trio can do moderate damage even after gaining levels but they aren't an effective tank due to Elden Ring Runes their modest health pool. However, what they are lacking in terms of damage output overall however, they make up by providing a great distractor during battles. You can call them up and watch as the wolves in spectral jump, gnash as they circle around their victims, breaking them limb from limb while you hang on the sidelines. It's a great experience while giving you time to relax and think about the next step.
My favorite thing about the spirit of the lone wolf in ashes is their devotion to the cause. Yes, they will are there for you to follow after being summoned. There's something incredibly charming watching these big-ass ghost wolves walk around in front of you, searching for the next target they can attack with their paws. They appear to attack together and coordinate their strikes to keep their enemies out. They are useful almost every day and are always there for you, even when they do get taken away one at a time.
I've become so attached to them to them that I've named the dogs after some of the best doggies from Tim Burton films: Persephone and Sparky from Frankenweenie as well as Zero in The Nightmare Before Christmas. It's a shame that you aren't able to pet them and teach them how to behave. They are, after all, ghosts. It seems like interacting with them is impossible however, there might be an item in best place to buy elden ring items the game for this.
