The third boss of falkreath Hold is bugged. The issue seems to be when you have a warden in the group.

So what happens? The three "mini bosses" will disappear, resetting the fight. This sometimes happens when you enter the arena. This isn't too big a problem, but is annoying and could potentially mess up speed run achievements. The bigger issue is this can happen at the second phase when the skeleton boss hits 50% health. The minis appear, then disappear. This causes the fight to reset and when the minis are down, the skeleton emerges at 100%. This it happens at this point in the fight, it happens every time you reach halfway, making the fight impossible. The only way to finish is to wipe, which resets the boss and hope for the first iteration of the glitch. This glitch seems to be happening 100 % of the time when a warden is present (with and without bear), but have not been able to recreate when no warden is present.

Have been farming falkreath the past two weeks, both on normal and vet. Our vet group is: dk tank, necro and sorc dds, and a warden healer. The minis always disappeared at the start of every fight. On normal, it's been me and my partner with two companions. Most of the time it was a dk, a sorc, and two embers. No issues. I decided to swap to my warden, with my partner on sorc, 1 ember, 1 bastion. The glitch occured both times we did this arrangement. I swapped to a templar, my partner swapped to dk, with an ember and a mirri. No glitch.

We are on PS5 NA.
