Not sure about the passives mainly, or how all the combos work at top level. Still leveling Occultism.

I am pretty sold on these:
O:
S:
W:


With 6 points left over,
In the maybe category (actives):
O:
S:
W:

And the big decision:

• Top-tier Occ passives
+ one of the Occultist maybes

-- OR --

• Top-tier Witch passives
1 Witch maybe + + (3 random maybes or 1 occ maybe and )

-- OR --
• Skip both cooldown passives completely and something like:
1 Witch Maybe + 1 Occ Maybe + +
