For some reason every time an enemy priest uses his holy radiance talent, my frontline gets hit for 50+ damage (and I do not mean the burn DOT that you can get from talents, that one comes afterwards) 

 

At lvl 4 this means two paired priests can basically oneshot me, forcing me to resort to really lame bait tactics (terrible AI uses radiance right away all the time) to kill them. Totally out of place with the other enemies at this level

This makes no sense at all, where is that damage coming from? I have a priest as well, I know how that spell is supposed to work.

This is no longer occuring it seems, on my newest run the priests only applied their burn DOT when I stood inside their Holy Radiance.
