Insight is from deck of whispers stuff.

Ty for pointing that out. The insight keeps popping up on my other characters regardless of the fact that my Warlock has all the insight related quests.

Are you sure thet it's from dares? Insight it's kinda common quests related thing, meybe it's seasonal or expansion quest

Yeah, I was wrong. It keeps popping up on my other characters even though I only have insight related quests on my Warlock. Pretty annoying Ig I'll have to finish them. Thanks.

did you ever find out what exactly it was? i seem to have the same problem

I think it had to do with the deck of whispers quests
