SPOILERS ( A world turned upside down)

[Sergeant Lamp]

I've experienced a bug where Uth Duna simply will not die. I'm doing plenty of damage, stunning him, avoiding getting hit. Landing solid blows from me and the environment. 20 minutes in, in the final arena, hes still chugging along and he's not even exhausted. 30 minutes in still nothing. So I just quit. I'm going to try again soon, but please tell me I'm not alone here.

I had the same issue with a Balahara, it was a multiplayer mission so who knows what desynced or what ♥♥♥♥♥♥♥♥ we were all connected to.

We quit after half an hour and restarted the hunt and then killed it in a few minutes at best.

It's possible the cutscene just failed to trigger, i swear that happened to me before...though not on Uth duna.

[Sergeant Lamp]

Well I did it solo first and I got all the cuts cents leading up to the fight. Is there cutscenes later on? This is chapter 5 btw if that was lost in translation. Not the first uth duna fight.

[PhantomΩ]

Oh i thought it was the first fight, no i don't believe uth duna on chapter 5 has cutscenes...i have a bad memory sorry.

Managed to complete it with my wife. Guess it was just bugged for me.

Same issue here, cutscene didn't work then it got unkillable (it still take damage but you can't wound him)
