so how do I counter Z burst dash in sparking

[Sorry, dudebros]

I straight up have no clue. can't block, can't vanish, can't use perception, can only hope to land a lucky parry since getting hit is 100% or use a character with an evasive skill

If this is the skill where they're dashing and quickly rushing around to your back. then all you have to do is move your character and press perception. when you move your character while theyre dashing it faces you toward them so you can do any of your counters
