I'm working on a new character with some conjuration backup; primarily familiar and flaming familiar. Do the atronach tree perks work on these? How about summon dremora lord? I've looked around and haven't found anything.

if you're gonna go conj. don't waste time on the familiars. get up to the atronachs. demora lord owns to know end

Atronach perks work for Dremora except for the 25/50% improvement perk.

My character is a wood elf and summoning a wolf or flaming wolf fits in with the hunter/animal friend theme I'm going for. I've got Kynes blessing, Hircine's Hide and Namira's ring and spend a lot of time hunting and gathering ingredients.

I can confirm that twin sould (two summoned creatures at one time) works on dremora, not sure about the other ones

bump

can anybody confirm whether the atronach perks twin souls elemental potency work on familiars?

That's exactly like the character I'm currently playing. Not far enough into it to help you unfortunately, but I really love the Summon Familiar spirit wolf- really wish there were upgrades for that. I want my spirit hawk, spirit ice wolf, and spirit bear Bethesda!
