Review time
1st skill = I think it's safe to buff it up a little, in both forms.
2nd skill = Protector form: Great supporting skill. I had a similar skill in one of my heroes

Avenger form: A little too much damage increase.
3rd skill = Now this one doesn't work that well. You won't be killing much units yourself (no AoE spells or anything) and you will have to depend on your allies killing units for this aura and for ulti too, which in some way means they will have to support you, not you support them.
Ulti = I don't understand the duration, try to put it a little more clear, or make a wider explaining in notes

Other than that, as I said you won't be killing that much units. What does "get phased" means? Like in phase boots?

I like the concept, just try not to depend on enemy deaths.
Plz review my entry
