I did fast dexterity/parry when grandmaster shoot special 1,That's weird kabam update the game problem...BUG.
Maybe send a video of the bug? I fought the grandmaster last week and didn't have any issues
His sp1 beam is unblockable unless you take the sp1 attack link node. So parrying it would just mean you get hit.As for dexing, it’s either you were too slow (his ai is fast and the beam can catch you) or your champion didn’t Dex because of input issues
