-Updated for Patch 3.9

-Updated for Patch 3.13


Betrayal League and Patch 3.5 introduced a completely new type of Damage over Time effects - Cold Damage over Time Spells. This new addition brought Vortex and Cold Snap (that were up to this point almost completely useless) to the highest Tier, making them contenders for being the best Boss killer skills in the game. Great Damage and Area of Cold DoT combined with an enormous amount of Energy Shield thanks to Occultist Ascendancy makes this build perfect for killing all the Bosses in the game, including Shaper and Uber Elder. Regeneration and a massive pool of Energy Shield make this build one of the tankiest in the game as well.

1. Gameplay

Our main skill for both clearing maps and bosses is Vortex. It is an instant cast skill, which means that we can cast it while running, without interrupting movement. The second most important skill is Cold Snap/Vaal Cold Snap, which is great to use against rare monsters and Bosses for more damage and for Maps clearing because it provides us with Frenzy Charges, which increases both Cast and Movement Speed. It will also apply Bonechill, which increases all our Cold Damage over Time and Chill Effect.

This video was recorded on a level 89 Occultist using Cerberus Limb, Solstice Vigil, and Rare Gear. I have decided to skip Elemental Equilibrium and self-casting Storm Brand/Orb of Storms. Instead, I took a CwDT+Lightning Golem setup. It made it less complex to play for the purpose of this video since I do not own a Crafted Sceptre to trigger those Spells. The video was recorded pre 3.13, we may update it eventually though you can assume Boss fights will be longer

2. Build's PROS & CONS

  • insane Defenses thanks to 10-15k Energy Shield and Curses
  • Shaper/Uber Elder viable
  • can clear all content in the game
  • survives even hardest hits from Syndicate members
  • good clear speed
  • Vortex is cast under your feet, so it's more of a Melee range skill
  • vulnerable to Elemental Reflect Map Mods


3. Leveling tips

For leveling, we are going to use Freezing Pulse, before we can switch Vortex at level 28. During leveling, it's recommended to use Life Gear, before you switch to full Energy Shield because it's easier to regenerate with Life Flasks. If you have enough gear with Energy Shield to make your play comfortable, you can do the switch at any time.
