How do I make an area-of-effect concentration healing spell?

[Mud]

Hoping someone can give me a hand here. I'm trying to learn how to make a follower that can heal, but the first hurdle is making a custom spell that she can use. In order to balance out what is essentially going to be free healing, I wanted to make her a concentration type area healing spell with a range of 36 and a self-only boost to armor and magic resistance, along with a combat override AI package to make her stop and channel the heal for 10 seconds when the player falls below half health.

 

I attempted to create the spell by copying the Grand Healing spell's RestoreHealthFFSelfArea Magic Effect, changing it to a Concentration type spell, increasing its area to 36 and then making a spell using this effect and regular fortify effects for armor and magic resist. But when I tested it in-game by adding the spell to myself, channeling the spell only seemed to have an effect on me, doing nothing to my nearby follower. So I think I need some help here, because either I flubbed something up or it's a more complicated process than this.

 

 

 

The second thing I wanted to do was make the spell grow in strength as the follower levels. Trying to add two heal effects to the spell with GetLevel conditions was no good, as it just applied both effects when cast at level 1 and increased the spell's cost for both effects. Do I need to do something with leveled lists or something?
