Black unicorns quest
 

Is there any reward for completing it? The quest log doesn't mention anything at all, nor did I pay attention if I got any experience from it.

Reward: 1200xp, 11000g

I think. Taken from: Banshee Guide

I stopped paying much attention to rewards after a while and just did everything regardless of if the reward was worth it or not.

I guess it's just an error then, or more likely an oversight.

Could be, I wouldn't worry over it, there's plenty of xp and gold around incase the reward really is "bugged" in some way. I'll try and remember to check when I play through there with my Mage.

I know you can "use" the staff quest item you get in order to receive one mind rune, but there should be an ordinary reward from it. What makes you think that there isn't one?

Yes, I know about the rune, and it was very welcome indeed. Like I said, the quest log doesn't mention any rewards at all, and I wasn't looking at my experience bar when I clicked to complete it.

Maybe the quest log doesn't mention the reward since the dude who gives you the initial quest (that black unicorn in 1000 rivers) doesn't give you a reward, but the druid dude does, I think, give you one.
