So, maybe I'm just crazy, but when I sometimes do a Group Dungeon, it's like my abilities use more Stamina/Magicka. I did a test while doing Wayrest Sewers, we were fighting Skeevers at the start, I used Engulfing Flames IV, then Eruption IV, followed by Burning Embers IV. No other abilities and each was done once, I ended up with little under 1/4 Magicka. Did the dungeon and then fought an Alit in Shadowfen, did the same combo as above and dropped to 1/2 Magicka. Both times I had the same buffs. So am I just crazy or..?
