I play a HELF melee with rogue dilettante, so I started playing around with a radiance (random-drop holy of radiance, not GS) weapon to get sneak attack damage while soloing. I noticed that the blindness effect goes off regularly, and I do get SA damage, but the blindness effect is rarely accompanied by the 4d6 of light damage that is supposed to proc with it.
Any thoughts on why that might be (besides a bug)? Might the blindness proc on unconfirmed crits, but the light damage only on confirmed ones? Or maybe blindness procs even if mobs make their fortification check, but light damage doesn't? (Not clear why either of those would happen, since description suggests they should proc together.)
I'm running primarily epic content at this point, if that's potentially relevant.
Thanks in advance!
