The Aetheral Crown, because you can have 2 Standing Stone powers active at the same time.
Right now, I have The Lord Stone active that gives me Physical and Magical resistance; and I have The Ritual Stone saved on my Aetheral Crown that allows me to raise undead creatures within a certain radius.
I am currently making an undead army in the basement of my house. Then I will raise them all at one time and become the infamous Necromancer Scourging Imp of Skyrim.
When your undead servants run their time limit and fall dead again, you can just take your crown off and put it back on again and your power will be recharged (you don't have to wait 24 hours!)
