I had trouble with mana in dungeons, so I put 5 points into Spirit Tap, in the shadow tree, and my other points are in Holy.
It’s very nice if I’m solo-killing mobs alone.
However, I notice it doesn’t proc all that often when I’m in groups and in dungeons. I went through a whole dungeon and Spirit Tap only activated about 3-4 times.
Is this how it’s supposed to be?
