Went into Mzinchaleft (always want to say Mzinchalet) today to get a sword. Reached the area where it is and a Sphere rolled out and a Master Steam Centurion stomped out. My character cast frenzy (she has Master of the Mind) and it affected the sphere. It attacked the centurion, but the centurion didn't fight back. The sphere killed the centurion after a long drawn out one sided fight. Was this a glitch or do centurions not attack other automatons? The spiders and spheres attacked each other.

Haha. very cool. I gotta try this some time.

The Centurions have a weakness to opponents who have a smaller hieght than normal, A skeever can take one down. I am willing to say a Chicken or Rabbit could do the same thing if they were agressive enough to actually attack a Centurion. Falmer will wipe the floor with them once they are close enough to avoid the Centurions Steam Breath

I was in Blackreach recently, and there are two or three centurions there. I released one, and the fight was as you described, only against Falmer. The centurion didn't do anything but take his lumps. I released another and he got into a fight with the giant. That one did much better, but he never used a ranged attack.

Thanks for the info. Everytime I've seen Falmer fight Centurions, the Falmer never got close. The steam and arrows cut them down. Now if I could get a pet rabbit, I'd drop him in a strategic location and cast Frenzy on him...instant Vorpal Bunny!
