Build overview



Boss DPS:



It's a very simple gameplay-wise build, but there are a lot of components necessary to make it work properly. You will deal Damage with Corrupting Fever - it's a Spell that makes your Hits apply Corrupting Blood on enemies which will deal Physical Damage over Time, but as you activate it, it removes a portion of your Life. The more Damage you want to deal with Corrupting Blood, the more Damage will you deal to yourself, you can even link it with Lifetap Support to further increase the DPS. The best way to scale the damage of this Spell is to increase the Gem Level, increase your Physical Damage, and Damage over Time, Spell Damage will have no effect. As your Gem Level is high and the Skill Gem properly linked, a single case would kill you instantly if you'd be able to use it - to avoid that you will cast Corrupting Fever for free.

One stack of Corrupting fever lasts only one second, an enemy can be imbued with up to ten stacks of it. To apply as many hits as possible in the shortest span of time use Cyclone combined with Ball Lightning and Cast While Channeling - Cyclone itself hits really fast and so do the lightning balls which are ranged, it's the best combination of Skills. Sire of Shards is the mandatory Staff that makes your Projectiles fire in all directions from you, without it you will severely lack AoE. Your build is Life-based and the best-performing class is Ascendant - Gladiator's Ascendancy gives you a lot of Damage, Chance to Blind, and Chance to Block Attacks and Spell Hits. With Occultist's Ascendancy, you're able to apply an additional Curse, increase effects of them, and be immune to Stuns.

1. Gameplay

The gameplay is very simple - you use Cyclone and enemies around you die. Use Flame Dash of Frostblink as your Movement Spell. Corrupting Fever can last for a very long time - the Duration of it is refreshed as you spend Life and you will spend a lot of it with another six-linked setup consisting of Cyclone and Ball Lightning. The Curses you should use are Vulnerability and Poacher's Mark, preferably as Ring mods. Your Auras are Pride, Malevolence, Flesh and Stone, Vitality, and if you have some space left - Herald of Purity. Additionally, use Blood Rage to generate Frenzy Charges and move faster.

This video was recorded on a level 94 Ascendant on Standard League. We had a level 28 Corrupting Fever from the gear, which resulted in approx. 3.5 kk DPS at maximum stacks. Overall it was an insanely smooth and balanced build, sadly with no the top tier single-target DPS given the required budget

2. Build's PROS & CONS

  • one of the best clear speed potential
  • really enjoyable gameplay
  • great survivability due to the Maximum Life and high Block Chance
  • it's a cyclone that shoots projectiles
  • strong single-target damage
  • you will be able to permanently uphold the maximum number of stacks on your enemy at all times
  • requires specific items, some of which may be expensive


3. Leveling tips

Start as a Physical Damage Cyclone. You can use Corrupting Fever early on, you will be easily able to sustain the damage. To transition to purely Physical Damage over Time from the standard Physical Damage a few adjustments have to be done - you will need Sire of Shards, an Amulet with the Crafted Mod "Skills Cost no Mana or Life while Focused", and your DoT already increased by Passive Skills such as Acrimony and the ones found on Cluster Jewels. It should be easily done after the third Lab. Use Vendor Recipes and Essences of Contempt on your gear for more Physical Damage with Attacks as you level up.
