Build overview



Boss DPS:



In Path 3.20 we saw a major overhaul to the Curse Skills. As the result, the Doom mechanic was removed, but all Curse-related Skills got a massive Buff. One such skill, Impending Doom is a topic of today's Build. It's a Support Gem that triggers a Doom Blast on the enemy when the associated Hex ends, and we can force that by overwriting it with a different Hex and exceeding the Curse Limit. You easily automate it with the use of Vixen's Entrapment. With just a single button press, you will cast 4 different Hexes, each accompanied by their repeats from Spell Cascade. It's important to note that only 3 Curses will actually affect monsters, one is here just to force early explosions. The essential detail here is that Hexes from your Gloves are Cast instantly when you start Casting your Curse Skill, so they are applied first, and their order is based on the Socket they are put in. Since Hexes usually are not meant to be spammed, they have pretty high Mana Cost which puts severe stress on your Sustain in this case. To counter that, we use Eldritch Battery with a high Energy Shield Recharge ratio. 

Poison is a stacking Ailment that deals Chaos Damage over Time and has a natural synergy with Chaos Damage and Curses, so we decided to scale the Damage that way. With a little bit of ramp-up, you will be able to reach absurd amounts of Damage. Temporal Chains and Despair are a great way to improve your Damage, and you can decide to use either Punishment or Enfeeble as your third Curse depending on whether you want more defense or offense. 

Since this Setup is based on Skills with Cooldowns, it's quite important to get some Cooldown Recovery on your gear. Fortunately, you don't need to stress over getting specific breakpoints, since Doom Blast can have up to 3 charges stored at once, so you won't "waste" it without a specific trigger rate. As a rule of thumb, just getting any Cooldowns and Cast Speed will improve your total Damage. 

The Build is not particularly tanky. You can easily achieve a decent amount of Maximum Life and Evasion Rating while also capping Spell Suppression, but it's prone to Physical Damage. Defensive Curses are a great way to improve that aspect, but they can be a bit unreliable. 

This Build works very well without any expensive Items and scales very well with your investments. Vixen's Entrapments are necessary to automate this setup, but they are very accessible even at the start of the new league.

1. Gameplay

You will be Shield Charging through the Map and exploding whole packs of monsters with a single cast of your Curse thanks to the Profane Bloom from Occultist Ascendency.  On Bosses, you will have to aim a bit to overlap your Curses, but thanks to the very big AoE you don't have to be very precise. Wither applied by Totems and passively through your Ascendency is a great way to improve your single-target Damage.

2. Build's PROS & CONS

  • insane Clear Speed
  • high Single-target
  • can be a league-starter 
  • immune to reflect
  • Hexproof maps are annoying (but doable!)
  • Mana Sustain problems even with Eldritch Battery


3. Leveling tips

You could start using this Setup very early, but getting enough Mana Sustain and Poison Chance at that point is quite hard to manage. We recommend leveling using Bane or Soulrend and transitioning to the final version when you get close to the Maps. If you do so, you can skip the Poison Passives and allocate some generic Chaos or Spell Damage Notables and respec them later for a smoother experience. 

Suggested leveling Gem setups:


Bane setup
Bane  Bane - applies linked Hexes and Chaos Damage over Time effect on all enemies in a radius. Deals More Damage per each Curse it applies. 
Despair  Despair - lowers Chaos Resistances of Hexed Foes.
Punishment Punishment - enemies at Low Life status take much more Damage. Low Life is applied below 50% of maximum Life.
void manipulation Void Manipulation Support - improves Chaos Damage dealt with linked Skills.
controlled destruction Support Controlled Destruction Support - grants a lot of Spell Damage at the cost of Critical Strike Chance. 
efficacy Support Efficacy Support - improves the Duration and Damage dealt by DoTs. 
Soulrend setup
Bane  Soulrend - as your secondary Spell you can use any other Chaos DoT, but we find Soulrend to work the best. It deals heavy Chaos Damage over a short time.  
void manipulation Void Manipulation Support - improves the Damage dealt with Chaos Skills. 
controlled destruction Support Controlled Destruction Support - Critical Strike doesn't affect DoTs, so it's the best pick here too. 
efficacy Support Efficacy Support - original duration of Soulrend is quite low, so improving it alongside its Damage is really beneficial. 
Auras setup
clarity Clarity  - grants a lot of Mana Regeneration to sustain your casts. 
grace Grace - Evasion Rating will be your main defensive layer later on. You can start using it quite early to have smoother leveling. 
flame dash Flame Dash -  a basic movement Skill that teleports you in a short distance. 
steelskin Steelskin - absorbs part of the incoming Damage and removes Bleeds.

5. Final Gems links

[DPS] Curse Setup

punishment Punishment - one of the Curses from this Setup is used purely to Trigger your Doom Blast and won't be affecting your enemies at all. It should be socketed in a top left socket in your Gloves. 
This Curse increases the Damage enemies take once they fall below 50% of maximum Life.
Enfeeble  Enfeeble - if you prefer more Defense, use this Curse instead. It significantly lowers the Damage dealt by cursed foes. 

Despair - this Curse lowers the monster's Chaos Resistances. It should be included in every setup. 

Spell Cascade Support Spell Cascade Support - you will need this Support here as well as in your Main link to keep triggering Doom Blast with a single cast. 
[UTILITY] Aura Setup
grace Grace - a very important Aura to keep you safe. It adds a lot of Evasion Rating.
Discipline  Discipline - improves your Energy Shield and its Recovery Rate. Use it only if you can't sustain casting otherwise. If that's not a problem, use Summon Skitterbots to apply Chill and Shock on your enemies.

enlighten support Enlighten Support - lowers the Mana Reservation of linked Auras. 
[UTILITY] Aura Setup

6. Gear Setup

The gearing choice is a healthy mix of Rare and Unique Items. The only Unique you truly need is the Vixen Entrapment Gloves, but there are a few Uniques that are quite cheap and extremely effective. The most important stats are the defensive ones - maximum Life, Spell Suppression, and Elemental Resistances should be your priority. Having a bit of extra Life Regeneration is also very useful. It's best to use Evasion and Energy Shield bases, as those are your main resources. As for Damage, your should mostly look for Cooldown Recovery Rate, Cast Speed and Chaos Damage. Ideally, you would want to get over 50% Cooldown Recovery Rate and 5 Casts per second, but any bit counts. Overinvesting in one category while neglecting the other part is not worthwhile. Curse Effect is a very valuable stat but its sources are very limited. 


Stat priorities on items:

  1. Cap Elemental Resistances
  2. Attribute Requirements
  3. Maximum Life
  4. Spell Suppression Chance
  5. Chaos Damage or Chaos DoT Multi
