Build overview



Boss DPS:



It's a classic Discharge build for the Assassin. Discharge deals damage based on how many Frenzy, Power, and Endurance Charges it has consumed. In the case of this build, these will be mostly Power and Frenzy Charges resulting in tons of Cold and Lightning Damage. Aim for a lot of Maximum Power Charges, Frenzy Charges will tag along via Badge of the Brotherhood Amulet. You can gain up to 12 Power and Frenzy Charges: three from the Skill Tree, one from the Assassin's Unstable Infusion, two from Void Batteries each, Rings, and a Corrupted Helmet. This flat damage is then increased by Assassin's Deadly Infusion, Opportunistic, and Ambush and Assassinate passives. It nearly guarantees a 100% Crit Chance with a high Critical Strike Multiplier, around 800%. The Damage is also noticeably improved with Pain Attunement Keystone and Surgebinders Gloves​​​​​.

Your Charges will be consumed each time you Discharge, so it requires a reliable source of these Charges. Power and Frenzy Charges are gained each time you enter Cat's Stealth thanks to Farrul's Fur. Cat's Stealth and Cat's Agility are two parts of the Aspect of the Cat Skill. It oscillates between these two phases every six seconds. That would normally require you to wait 12 seconds each time you want to Cast Discharge, but thankfully you can Reduce this Skill's Effect Duration to a fifth of this value. Allocate Window of Opportunity Notable and its Mastery for reduced Skill Effect Duration, and in the item in which the Aspect is present, socket two Support Gems that reduce Skill Effect Duration. Such a setup creates an opportunity to use Lightning Warp as your main mobility Skill. The build is able to Cast a fully charged Discharge every ~2.5 seconds, which is enough as the base Cooldown of Discharge is 2 seconds. We recommend lowering it to around ~1.75 seconds with Cooldown Recovery Rate modifiers, as it has 0.75 seconds of Cast Time that needs to be accounted for. The build has very high damage, but it's not very tanky, at least not unless you swap your Hatred and Wrath Auras for Grace and Determination. It would lower your damage by around 25%. The build struggles with Physical Damage, without Determination its Armour is very low, but it has a high Life Recovery Rate that is somewhat necessary as the low Cast Rate of Discharge makes Leech not enough of a Recovery tool. Implementing Petrified Blood is a good idea, it's excellent with passive Life Recovery.

1. Gameplay

Use Discharge to deal very high damage with a huge area of effect. You won't need to use Flasks, Charges will be recovered automatically. To move quickly cast Lightning Warp. For Curses select Elemental Weakness and Frostbite. For a better Life Recovery use Stone Golem. Be sure to activate Righteous Fire during boss fights. For a Guard Spell, we recommend Molten Shell. Your Mana-reserving Spells are Zealotry, Hatred, Wrath, Vitality, Defiance Banner, and Petrified Blood.

2. Build's PROS & CONS

  • very high damage
  • good clear speed due to quick Lightning Warp and enormous Area of Effect of Discharge
  • high Life Regeneration
  • the best-in-slot items are quite expensive
  • poor durability


3. Leveling tips

Start as an Assassin Spell Caster - that's a very general lead but there's not much you can do before adjusting your build for Discharge. After completing the first labyrinth you can immediately start specializing in Power Charges scaling and Critical Strikes - get Unstable Infusion and go for Maximum Power Charges on your Skill Tree. We recommend using Arc as your main Spell. You can start specializing in Critical Strikes very early on, around the time you finish the second Lab. Switch to Discharge after allocating all Maximum Power Charges, equipping two Void Batteries, and Farrul's Fur.

5. Final Gems links

[DPS] Discharge setup
Discharge Discharge - It deals a lot of damage around your character and consumes all your Charges. The Phantasmal version is the best one if you can generate Endurance Charges. It will deal mostly Cold and Lightning Damage.
Empower Support Empower Support - Increases the Gem Level of Discharge.
Elemental Focus Elemental Focus Support - Grants more Elemental Damage, but makes you unable to cause Elemental Ailments like Chill and Shock. Hypothermia Hypothermia Support is the substitute if you're using Heatshiver.
Concentrated Effect Concentrated Effect Support - It grants more Damage but reduces your AoE. Good for bosses, but for clearing swap to Increased Area of Effect Support Area of Effect Support​​​​.
Elemental Penetration Elemental Penetration Support - The build has already high base damage, high increased and more Damage, Crit Chance, and Crit Damage. It only needs Elemental Penetration.
Increased Critical Damage Support Increased Critical Damage Support - It increases Critical Strike Damage - your Crit Chance should be 100% to make the best use of it.
[MOBILITY] Aspect of the Cat and Lightning Warp setup
socketed in an item with the Aspect of the Cat
Lightning Warp Lightning Warp - Your Skill Effect Duration is very low, rendering Lightning Warp the best Movement Skill.
Swift Affliction Swift Affliction Support - Reduces Skill Effect Duration again so that you can Warp faster.
Less Duration Less Duration Support - Lessens Lightning Warp Duration. It should also affect the Aspect of the Cat Skill - it will switch between Cat's Stealth and Agility faster, granting you Charges more often.
Inspiration Inspiration Support - Lowers Mana Cost of Lighting Warp. Lifetap Lifetap can be used too to spend no Mana on it at all. Alternatively, socket Faster Casting Support Faster Casting Support here to Cast Lightning Warp faster.
[UTILITY] Auras setup
Zealotry Zealotry - Grant you more Spell Damage and Crit Chance. It creates Consecrated Ground which provides you with Life Regeneration and reduces the Effect of Curses on you. The Divergent one is great, it gives you Life Regeneration.
Hatred Hatred - Use it for simply more Cold Damage. Determination Determination can be used instead to gain more Armour, it's great if you lack defense - your damage should be high enough anyway.
Wrath Wrath - Wrath adds Lightning Damage to Spells and grants more Lightning Damage. Divergent one increases its Reservation Efficiency. Alternatively, use Grace Grace for extra Evasion if you don't really need that extra damage.
Enlighten Enlighten Support - Linked Auras reserve less Mana.
[UTILITY] Petrified Blood setup
Petrified Blood Petrified Blood - You're on Low Life to benefit from Pain Attunement. Use Petrified Blood to Reserve half of your Life, and to redirect a portion of incoming damage to be taken as DoT. It's good with Life Regeneration and Life Recoup. It will reduce your durability, but not by a lot. An anomalous quality is better, it prevents more Hit Damage.
Arrogance Arrogance Support - Petrified Blood Reserves Life instead of Mana. Anomalous quality increases Life Reservation Efficiency by another 4%. It will Reserve around 57% of your Life, but you can make it 50% with another Enlighten Support Enlighten Support.
[UTILITY] Curse setup
Elemental Weakness Elemental Weakness - Reduces Fire, Cold, and Lightning Resistance of your enemies.
Frostbite Frostbite - Reduces the Cold Resistance of your enemies. An Anomalous one is a bit better.

[UTILITY] Stone Golem
Summon Stone Golem Summon Stone Golem - Stone Golem grants you Life Regeneration, even more of it if it's from an Anomalous Skill Gem.
[UTILITY] Vitality
Vitality Vitality - Vitality simply grants you Life Regeneration.
[UTILITY] Molten Shell
Molten Shell Molten Shell - Set it up as your movement key. It's good if you have somewhat high Armour, it creates a protective barrier that absorbs more damage the more Armour you have. If your Armour is too low to make it useful, choose the Withering StepWithering Step instead.
[UTILITY] Righteous Fire
Righteous Fire Righteous Fire - It grants you more Spell Damage as it says active. If you can't sustain it, use only the Vaal version that "damages" you only once. The Divergent version grants you more Spell Damage.
[UTILITY] Defiance Banner
Defiance Banner Defiance Banner - Use it for increased Armour and Evasion. It reduces the Critical Strike Chance for nearby enemies.

6. Gear Setup

The Required Unique items are Void BatteriesFarrul's FurSurgebinders, and Badge of the Brotherhood. On your Rare items, you have to have Aspect of the Cat Skill, and preferably a source of Elusive (found on Boots, but you can also use Withering Step Skill) and Exposure (which can be gained from a Cluster Jewel or Flask). Prioritize high Life Regeneration if you want to sustain Life Drain from regular Righteous Fire. Life Leech or Life Gain on Hit can be useful in this regard. Some Items or modifiers may give you an extra Power Charge or stats tied to the number of your Power Charges such as Life Regeneration - these are particularly good. You don't really need Cast Speed as the Cooldown of Discharge is bottlenecking your Cast Rate. You can obtain Cooldown Recovery from Forbidden Jewels, Tattoos, Belt, and Boots. You will deal mostly Cold and Lightning Damage due to the abundance of Power and Frenzy Charges. Your Crit Chance should be easily capped at 100% due to Assassin's passives, Crit Multiplier will be much more important. After that, seek Elemental Penetration. You don't need any added damage. The build requires 155 Strength for Molten Shell and Petrified Blood. It can be found on Rare Items' Suffixes or Tattoos. You will need to reduce Mana Cost of Skills and get some Reservation Efficiency if you wish to comfortably use all the presented Auras and Spells. These can be found on a Rare Helmet, Jewelry, or Anointed on your Amulet. If you plan to cap your Spell Suppression, you will need to go for the Inveterate notable and gather the remaining 43% from your Rare Items. You can also go for Instinct notable for another 22%.
