Why does my Mayhem Berserker keep dropping out of Mayhem?

I rarely notice it in Chaos Dungeons but it happens constantly in Thornespire.

I play with an Xbox controller and I disabled the “b” button mapping that would normally be used to manually disable Mayhem. I verified that I can no longer manually disable it.

I am guessing that for some reason it switches when my health gets really low but I am not aware that this is a documented feature.

I am loosing Mayhem about 4 or 5 times per level and with the 30 second cool down the content is a lot harder this way. What am I missing?

Hello @Dmitri

Hope you are doing great and apologize about this situation where your Myahem ability is getting disable.
I would like to ask if this happens only with the controler or also with the keyboar?
My suggest will be to create a web ticket reporting this error on your character so it ca be properly investigated.

Best wishes hero.!
