Mind over matter, Eldritch Battery and aura managing discussion

The first time I saw this passive, I thought "wow so OP". Now I'm actually planning build arround it and I understand how much points you need to get it with Eldritch battery. This points wasting makes much more sense now because you will have much less potential for aura building. I can't see viable way to get enough passives to run third aura if you build MoM+EB.

So here is my first question:
1) Is it possible to make "mind over matter" build without eldritch battery?

And second question:
2) Does any option to run 3 auras(hatred, determination, grace) except picking up 3 clusters of mana reservation exist?

Here is my build for MoM+Eb+Spectral throw I come up with:

1 - Yes, but it won't be nearly as effective. You need a LOT of Mana.
2 - With an Alpha's Howl, maybe. Or you run one on Life...

Having lots of auras will make you have less effective mana for your mind over matter which will reduce its effectivness and you could take one more node near scion for 40% mana regen those 40% mana regen are very nice with eldrich battery.
