Inquisitor's Cast on Crit Cyclone builds with Mjölner that automatically triggers Lightning Spells are one of the smoothest builds to play. There are two main damaging Spells - one that you can trigger on Hit with your Mjölner, and the other one is a Cyclone linked with Cast on Critical Strike Support Gem. Mjölner is a One-Handed Mace that requires a lot of Strenght and Intelligence but has a high frequency of Spell activation. Cyclone is the fastest Attack in the game, which allows the character to cast a lot of spells in a short span of time as well. Inquisitor is the best-suited ascendancy - Righteous Providence increases the Critical Strike Chance based on our Strength or Intelligence, which is needed anyway to Wield the Mjölner. Inevitable Judgement lowers on even completely ignores enemy Elemental Resistances when you strike them with Critical Hit. Sanctuary and Pious Path increases and improvers by new features the effectiveness of Consecrated Ground.

This is a Low-Life build that uses Shavronne's Wrappings and Prism Guardian. You rely completely on ES, which will be regenerated by Consecrated Ground and Fenumus' Spinnerets - it's possible to reach around 6k or 7k of Energy Shield. The Presence of Chayula will fix your Chaos Resistance, give you more ES and Stun Immunity - which is especially useful with Cyclone. With Prism Guardian you will be able to accommodate three more Auras at the cost of your Life Pool. Other Unique items suit this build very well. The build is generally cheap when it comes to Unique Items - most of them are worth a few Chaos Orbs, Jewels, and Cluster Jewels, however, can get quite expensive.

If you plan to elevate this build to its maximum potential you can swap the Shield to The Squire - one of the most expensive Unique in the Game. With this Shield on you can make a six-link out of your Mjölner setup. By ditching the previous Shield that was quite essential to the build you will have to make some more big changes as well - use Aul's Uprising, free Determination Variant. You won't use Shavronne's Wrappings as your Build will be more Life-based, with some of your Auras reserving Life via Arrogance Support. Additionally, put Glorious Vanity in one of the sockets near a Keystone to get Corrupted Soul. The upgraded version of the build is expensive, this end-game variant of the build will be referred to as The Squire version.

1. Gameplay

The gameplay is fully automated, all you have to do is press and hold the Cyclone button and hit enemies - it will activate your Arc on Hits and Ball Lightning on Crfits. Vaal Righteous Fire can be used during boss fights for more Spell Damage. There's also your movement Spell - Frostblink of Flame Dash, and Bloodrage that you have to activate once or twice during the whole mapping experience. The Curse on Hit should come from your Ring, Immortal call is automatically triggered after you take damage. 

This video was recorded on a level 95 Inquisitor on Scourge League with the Squire Shield, Aul's Uprising, which made this character nearly unkillable and significantly boosted the damage of Arc. It still feels a bit lackluster in terms of single-target Damage, but melting end-game Bosses has never been this build's main objective

2. Build's PROS & CONS

  • good AoE, despite it being a Melee build it has the potential to quickly dispose of trash enemies
  • great single-target damage 
  • solid defenses based on ES and its regeneration
  • can run into Mana issues
  • reaching the required Strength might be a problem


3. Leveling tips

It's an ES-based build and you won't be able to level relying only on Energy Shield, the transition from leveling gear to endgame gear won't be smooth as it usually is. Start with Elemental Spells such as Arc, cast it manually, and gather some Maximum Life while still trying to build your tree around the final set up so you won't spend too many Orbs of Regret. Around level 60 you will be able to wear most of the necessary unique items, respec the unnecessary nodes and follow the final Skill Tree after that. On your gear look for Lightning or Elemental Damage, Critical Strike, and Maximum Life with Elemental Resistance.

Suggested leveling Gem setups:

Arc setup
Arc Arc - You will use Arc or any other Lightning Spell that suits you. Arc is good for clearing but bad against bosses, that's why you can consider Ball Lightning as well.
Added Lightning Damage Added Lightning Damage Support - adds flat Lightning Damage to your Spells and Attacks
Inspiration Support Inspiration Support - Skills cost less Mana, have higher Critical Strike Chance, and increases Elemental Damage
Arcane Surge Support Arcane Surge Support - more Spell Damage, increased Cast Speed and Mana Regeneration as you spend Mana on Skills
Flame Dash setup
Flame Dash Flame Dash - use Flame Dash or a Frostblink for better mobility
Lifetap Support Lifetap Support - spend Life instead of Mana on your movement Skill
Utility Gems
Wrath Wrath - Wrath is the Aura dedicated for build dealing Lightning Damage, it adds more of it to your Spells and Attacks
Herald of Thunder Herald of Thunder - Grants more Lightning Damage and creates storm which hits enemies dealing Lightning Damage
Clarity Clarity - used for faster Mana Regeneration


You should kill all the Bandits and take two more Passive Skill Points

Leveling Skill Trees:

32 Points Skill Tree
Take Retribution, Sanctity, and the head for The Cruel Preparation as Shown. Take Elemental Damage nodes as you see any nearby.

74 Points Skill Tree
Look for more Critical Strike nodes and Maximum Life and Mana. Lightning damage nodes are useful as well. Start to look for ES gear from now on.

5. Final Gems links

[DPS] Ball Lightning setup
Ball Lightning Ball Lightning - Ball Lightning is great where Arc lacks its virtues and vice versa. This Speel is great for single targets, it can travel independently of enemies' position and can hit targets far away from you.
Cast on Critical Strike Cast on Critical Strike - you should be able to reach around 100% Chance to Crit, meaning each Hit will trigger Ball Lightning, with Cyclone's extraordinary Attack Speed it will be quite often
Cyclone Cyclone - the sole candidate for all CoC setups - allows you to travel during its Channeling and has the highest Attack Speed of any other Attacks but the Damage of this Skill is negligible in general
Inspiration Support Inspiration Support - use it to lower Mana Cost, increase Elemental Damage, and Critical Strike Chance for Skills you use constantly
Slower Projectiles Support Slower Projectiles Support - it's great to have slower-moving projectiles as they will stay close to your target for a longer period of time, damaging it constantly, the projectile damage is also increased; you can also use Greater Multiple Projectiles
Increased Critical Strikes Support Increased Critical Strikes Support - use it to have a higher chance of triggering Spell on Hit, and to deal more damage with the Spell itself
[UTILITY] Aura setup (Life Reservation)
(socketed in Prism Guardian)
Zealotry Zealotry - Very important Aura - it has a chance to create Consecrated Ground as you Hit Rare or Unique enemies - during boss fights you might run out of Sulphur Flask Charges. It increases your Critical Strike Chance.
Wrath Wrath - adds Lightning Damage to your Spells and Attacks which is the type of Elemental Damage you're mostly dealing
Vaal Discipline Vaal Discipline - Gives you more Energy Shield - around 1k later in the game. Vaal version grants you a temporary buff where ES Recharge is not delayed by damage.
[UTILITY] Aura setup (Mana Reservation)
Herald of Thunder Herald of Thunder - The optimal choice of a Herald for Lightning Damage-based builds, it grants you more Damage of this type and creates storms that hit enemies as you kill them while they're Shocked
Flesh and Stone Flesh and Stone - Stay in Sand Stance at all times to blind nearby enemies and to take less damage from them, Flesh Stance grants you close to nothing
Precision Precision - More Accuracy Rating and increased Critical Strike Chance, one of the most important Auras to increase the DPS
Enlighten Support Enlighten Support - it makes the skills in this setup Reserve less Mana
[UTILITY and MOBILITY] Clarity, Vaal Righteous Fire, and Movement Skills setup
Clarity Clarity - it's an optional choice since you might run out of Mana to Reserve but you should be able to have it at level 1
Vaal Righteous Fire Vaal Righteous Fire - use only the Vaal component of this Spell for more Spell Damage during its Duration
Frostblink Frostblink - Frostblink is used to quickly relocate and dodge hits, it can be replaced with Flame Dash depending on your personal preferences
Arcane Surge Support Arcane Surge Support - Keep Arcane surge at a low level, so that one single cast of Frostblink will activate its Buff that grants more Cast Speed, Spell Damage, and Mana Regeneration
[DPS] Arc setup
(socketed in Mjölner)
Arc Arc - Arc is really great to deal with a large number of weak enemies - it instantly hits a pack of mobs dealing Lighting Damage and with the insanely fast casts thanks to Mjölner and Cyclone the clear speed is one of the best you can get
Increased Critical Strikes Support Increased Critical Strikes Support - increases the Chance that Arc will Hit Critically
Added Lightning Damage Support Added Lightning Damage Support - adds Lightning Damage to Arc
[UTILITY] Blood Rage and Immortal Call setup
Blood Rage Blood Rage - use Blood Rage with high Gem Level and Quality to increase your Attack Speed, meaning your Spells will be cast more often
Increased Duration Support Increased Duration Support - increases the Duration of Immortal Call and Blood Rage
Cast when Damage Taken Cast when Damage Taken - will automatically trigger Immortal Call, Blood Rage has to be turned on manually
Immortal Call Immortal Call - keep Immortal Call at level 3, and CwDM at level 1 so that it will trigger more often
[UTILITY] The Squire setup (an alternative to Prism Guardian)
(socketed in The Squire)
Elemental Focus Support Elemental Focus Support - you won't need two sources of Shock, so it's perfectly fine to have this Support Gem to increase your Elemental Damage
ncreased Critical Damage Support Increased Critical Damage Support - your Critical Strikes Deal much more Damage by up to additional 150%
Inspiration Support Inspiration Support
[UTILITY] The Squire setup (an alternative 4-link setup)
Vitality Vitality - Vitality regenerates your Life at a steady rate
Defiance Banner Defiance Banner - use it for more Armour and Evasion Rating and to reduce enemies' Crit Chance
Precision Precision
Arrogance Support Arrogance Support - all linked Auras should Reserve Life instead of Mana
[UTILITY and MOBILITY] The Squire setup (an alternative 4-link setup)
Wrath Wrath 
Zealotry Zealotry
Flame Dash Flame Dash - a movement Skill that can be replaced with Frostblink, depending on your preferences
Enlighten Support Enlighten Support
[UTILITY] The Squire setup (an alternative 4-link setup)
Molten Shell Molten Shell - grants you a temporary damage reduction, the Skill can prevent more damage the more Armour you have
Tempest Shield Tempest Shield - massively increases your Block Chance for Attacks and Spells, grants immunity to Shock, and damages enemies in a fashion similar to Arc on Block
Determination Determination - WIth the right version of Aul's Uprising you should be able to have this additional Armour-granting Aura at no cost
Enhance Support Enhance Support - increases Quality of linked Gems, it's especially useful with Anomalous Molten Shell

5. Gear Setup

At first, you should of course cap your Elemental Resistances, then your Priority is to have a decent amount of Energy Shield. The biggest problem after that will be to meet the requirement for Mjölner - 412 Strength. As your Gear will be mostly Uniques, you will have to look for this Attribute on Rings, Jewels, and Belt. In fact, these gear pieces are the only rare items here, and you will need to cap your Elemental Resistances there as well. It's probably the biggest challenge of this build to balance all these requirements with almost no room for stats that are absolutely mandatory.

Our recommended items will:

  1. Cap your resistances 
  2. Give you enough DPS/Life to start mapping successfully

Stat priorities on items:

  1. Elemental Resistances
  2. Energy Shield
  3. Strength
