Was doing a Barbatos yesterday and the phase I was in the people were 'farming' the bats. I figured I'd help as I could use the count and if I got 4 or 5 before Barb went down...coolio. There was one tank who was dragging this bat around since it came out and everyone wailed on it with guitars and it had NO chains. Never took damage. A few others came up and did go down, but this one guy...nah, only went when Barbie also went down. I was out of town when the fix went in....and haven't really done much down there since....thought this was fixed with the update, or just fixed-'ish'? Or was this a fluke?
I assumed they were *going* to do it but couldn't yet- looked like this in notes Episode 43: Dark Knights Death Metal Washington, D.C. None of Barbatos' Bat Illusions should remain unkillable after being hit by enough guitar-wielding player attacks.
