I've seen some people discuss the idea that atromancy, the perk that increases the summon time by double, and there's another one that increases it's damage by 50%. Do both of these work on him?

All the atronach perks work for Dremora except for the +50%. This means duration, distance, and getting two of them.

Well that's kinda of lame e.e, but he is alredy powerful enough i guess... if the 50% worked on him he could probably 1 shot everything.

Thanks for the response.
