Anyone else find that the summoned Atronachs are very poor at using their ranged attacks? They seem to have no sense of what constitutes a clear line of site for their ranged attacks. I frequently see my Storm Atronach floating behind some waist high obstruction casting away and striking the obstruction directly ahead of him. I absolutely understand an occasional miss, but one would think after a few mindless blasts to the wall, it would move or adjust or something...

Where can you get the spell tome for a storm atronach?
