Yesterday while running through Uldaman with a group, I noticed that my mana was fluctuating. I noticed that it peaked as high as 2000 and dipped as low as 1700. I checked the buffs I had on, and none of them should have increased or decreased my intellect. It was late so I could be mistaken.
For the record I had Retribution Aura, Blessing of Sanctuary, Righteous Fury, and one of my Seals on. The only buffs I can recall getting from my group members were Power Word Fortitude, and Mark of the Wild.
Is there something I'm missing as to why my mana kept fluctuating?
