on whether or not it is an attack. It isn't stopped by Oblivion Shield, it doesn't seem to get evaded by some dodge effects, but it removes Portal Walker. Also, you can use it while Wandering (or at least Brainless) even though it's a relocation effect.
I think we'll be forever plagued by these issues until the game gets an overhaul of its combat engine. It's just an unfortunate effect of how Pox grew over the years.
