Call me stupid, but Clairvoyance doesn't work for me. I mean I use the spell, but nothing happens. Does it only work in dungeons?
I turned off the compass last night and it was a huge improvement in immersion. But when I tried casting Clairvoyance it also seemed to just 'poof' like a failed spell.
Then I realized that this is a spell that only works while you are holding the cast button down...not on the release of the cast button. (I.e., it works like a ward rather than like a summon.)
