Chaos Oracle help

I'm making an Oracle ED/C Dark Effigy Totem build and I've been trying to balance my skill tree around Skill Effect Duration, Chaos damage, Mana Regen with MoM, and not using all 100 points.

The first most important thing is Skill Effect Duration because I think(?) it will be good for the DoTs, Poison(s), Dark Effigy Totem length. I think it's will what my build feel so smooth to play.

The second is definitely the 50% Chance to fire 2 Additional Projectiles because I'll also be running the 'Chaos Bolt' implicit spell from wands.

I don't have Path of Building here on my work laptop, so I just created something in PoEPlanner.com

What do you think?
