Dayum! sums it up adequately.

It doesn't matter what I launch it on, it's dead. It brings down Dragons and is relentless once they land...

Curious though why I've not heard that much about it on the forums. I just wish I'd know of this at level 9 or so....

I always make one of these ASAP, once I join the College (if I join, that is). They are a phenomenal assist to a low to mid level character.

I make that staff as soon as possible and it makes for a very powerful lower level character. I don't use it a lot so the game stays challenging but it does wonders for the confidence level just knowing I have it.

whats so special about them? I mean as apposed to the spell conjure storm antronach?

They launch wicked lightening at their enemy and drain them mercilessly until they die. You just gotta see it to appreciate it. I don't know if I'd say he's better than a Frost Atronach, but he does seem to take down my enemies quicker than either of the other two Atronachs.

He's so scary I usually run away throwing glances over my shoulder.
