I thought the effect was gonna be passing so I didn't record exactly when it happened, sorry. I think it happened some time around getting the No Pity for the Lost ability. It doesn't impede the game or anything but it's a bug nonetheless, though I'm sure you have more important bugs to deal with before this one. I'm currently playing a priest of Berath so I'm thinking it's kinda a death guard hands effect...! 

Greetings,

 

And thank you for bringing this issue to our attention We'll add this to our date-base for our Developers to investigate further.
