I league started with cold bv Occultist and wanted to share a quick writeup.

Here is me at level 89 atm (T12 maps currently) with level 19 gems:

The idea from the build came from Allie: https://www.youtube.com/watch?v=ek5vFbmHECI

While playing the build I came around this guy: https://poe.ninja/challenge/builds/char/sping0425/Kalandra_Blade_Vortex?time-machine=day-3&i=0&search=time-machine%3Dday-2%26class%3DOccultist%26skill%3DBlade-Vortex%26item%3DTulfall%26sort%3Ddps%26blade-vortex-support%3DUnleash-Support

He had some very interesting ideas that I adapted.

Level 1-12

I went with Freezing Pulse, Holy Flame Totem and Frost Bomb. No issues whatsoever.I did what Allie suggested and b-lined to the brand nodes asap. Was a really good choice. Winterbrand is amazing.

Level 12-41

Winterbrand, Frost Bomb. After the brand nodes I went for the cold nodes at the top of the tree. Everything was chilled nicely and leveling was a breeze.

Level 41-70

I bought Nycta sceptre which requires level 41 and Princess sword for the offhand and had a 4link ready for BV. I could not afford Hrimsorrow yet. But it was the next upgrade I bought asap once I could afford it. I unspecced out of the brand nodes and got the skill duration nodes below witch and the unleash nodes top right of witch. Leveling with BV with the 2 weapons was insane.

Starting from act 6 I bought every lockpicking, deception or perception heist contract I could get. I converted all my currency to chance orbs to buy them. I would keep them for later.

Before act10 Kitava I stopped. I did my third lab. Void Beacon and Frigid Wake I had already. The third one was Forbidden Power. By that time I had found the build from ninja with Tulfall and Malachai's Loop. I liked the concept alot. So I ran a lot of my heist contracts to buy Tulborn, Tul's Blessing (Tulfall), Malachai's Loop, Doryani's Invitation and Replica Inya's. I bought a rare amulet too. Rest was stuff I had found while heisting.

Once I got those items I started mapping which went really well. I gathered a bunch of Kalandra maps which I ran yesterday. I got 2 divines. One of which I invested into Badge of the Brotherhood, Taste of Hate and a synthesis helmet with +1 power charge. The build has really good synergy and thanks to Eldritch Battery has no mana issues at all and can run another aura.

Additionally I bought 3 Grand Spectrums. But I did not buy the min power charge/endurance charge ones. I went with the crit chance ones which where affordable and give really nice damage too.

I am in T12 maps right now and I am dying super rarely. Stuff gets frozen to death/insta-popped most of the time once I touch it. There are of course some absurd nemesis combo's that absolutely shred. But that is for everyone.

The build is a mapper of course and endgame bosses will be a struggle. All in all it is my first bv build and I really like the ice pops.

I went Malediction as the fourth ascendancy since it adds a lot of damage with the Arcanist Brand setup on rares/bosses. Most rares pop instantly though.
