So I am lvl 27 Templar with two-handed weapon, I know... it was my first build, however, I'm in the dungeon "Sanguine's Demesne" and I can take on two or three at most but there were mobs of five or six. So as I'm standing there contemplating how to do this or just wait for some others to pass by, when this guy comes along.

Let me set the stage, he is wearing a robe and wielding a two-handed sword and he was my level, 27. He cuts down a mob of six daedra, with two of them being spell casters, in matter of five seconds. I couldn't even get to them fast enough to get in a hit. It looked like he was using some spell to hurt them and then throw the entire mob to the ground. It also looked like he had some spell on himself that was spherical and encompassed his whole body.

I haven't been playing long enough to know what in the world he did. Does this make sense to anyone? I would love to be able to make a new build like he had. I was going to whisper to him but he went really fast and I got left behind at the shyshard when the baddies reappeared and died very suddenly. I've tried doing research on all the classes but I can't find any spell like what I think I saw happening.

Any help would be appreciated.
