Hey,

A couple of questions about the battle with Sarantha.

[+]

It looked to me as if she has a fire column then a shock-wave. Did I see correctly that the fire part restores her health?

After several restarts...

[+]

I decided to run away and get to a opposite quadrant from where she was at. This seemed to work until I was blasted out of the arena.

Since I am a Mage, I tried both fireball and shock spells...

[+]

It seemed to me, the shock worked on her best, did anyone else compare fire verses shock?

After it was over, I tried a previous restart...

[+]

And then using the console command 'kill', I was able to loot her, and saw she has a nice sword. I then restored to a non-cheat save and played with out a cheat. At the end of the battle, I was placed to far from her to loot the sword. Is obtaining this sword not possible with out a cheat?

You shouldn't be able to loot the sword normally.
As for the shockwave, the trick here is to stand at places where you can't get blasted out of the level. For example, in the middle of the arena, or in front of (not behind) a pillar.
