Help for me new HC Scion

Hey guys,

after my witch hit the floor today i wanted to try out a raging spirit scion, but i do need some help i think because i have no idea if it will work - i am still quite new in the game.

Where my Skilltree is so far:

So so final plan:

Probably i will never get to the final version.. ^^

Anyways, my plan was to max out my options to fast cast Raging Spirits while help them out with auras and curses. I was thinking of getting Conduct too, but i have no idea how the get any charges. the skill points for getting Charisma are optional, because i feel like it is quite off my track.
Also Path of the Savant does not look too smart, because Skulls do not seem to get any Bonus from the Spell damage as far as i know.

On he side, i wanted the charakter to be good for parties while also being quite tanky.

What do you think of it?

I made some changes to my final tree idea...

I think like this i could get more out of it.

Although i feel like i am talking to myself here....
i was thinking of dropping maybe out of the minion damage above witch and instead to for mind over matter:

also i put some points into the cast speed close to shadow to make up the loss of cast speed above witch. although loosing 30% minion damage sounds like hurting, i feel that it might be better to invest in defense. the mix of EB and MoM should make my defense skyrocket i hope.
