Arc Lash Sorcerer Endgame Build for Diablo 4 (Season 4)

Build Introduction

The Arc Lash Sorcerer build is ideal for players wanting a simple, yet effective, melee playstyle. This is the fastest Sorcerer build in terms of mobility, and the build is extremely effective at speed-farming all endgame activities in Diablo 4.

Compared to similar Lightning Sorcerer endgame builds that are ranked high on the tier list, like Ball Lightning and Charged Bolts, the Arc Lash Sorcerer has lower single-target damage. The Arc Lash Sorcerer clears easy content faster than any other build, but bosses can take longer to kill.

This endgame build guide assumes your character is at least Level 50. Check the Sorcerer Leveling Guide if you need help getting there.

Slot Teleport in the second Enchantment Slot. Utilize the synergies in the Telestomp build variant for speed-farming.

Paragon

Paragon unlocks after reaching Level 50, and the progression system offers a considerable boost to character power. The images below provide a visual of each Paragon Board setup for the Arc Lash Sorcerer.

Important Notes:

• Make sure you select the correct Legendary Boards and rotate them into the correct orientation.

• Additional bonus requirements on Rare Glyphs may not be obtainable until they gain increased radius range at Level 15.

1. Starting Board (Flamefeeder)

Socket Flamefeeder for increased damage to Burning targets. Prioritize leveling Flamefeeder to 15, as the increased radius is needed to allocate 25 Dexterity for the additional bonus.

Prioritize leveling Reinforced to 15 to gain increased radius, as it is needed to obtain the Damage Reduction in the additional bonus. The Legendary Node on this board is not utilized.

4. Enchantment Master (Territorial)

Attach the Enchantment Master board without any rotations. Socket Territorial and prioritize leveling it to 15 for the increased radius to obtain the additional bonus. The Legendary Node on this board is not utilized.

Gear, Gems, Elixirs, and Stats

Season 4 brings an incredible shift in character progression systems. The major rework to itemization and crafting in Patch 1.4.0 changes the core mechanics of Diablo 4, and the changes will remain in effect beyond Season 4. For further details, read the overview in the Tempering and Masterworking section.

Legendary Aspects

Listed below are all the best-in-slot Aspects for the Arc Lash Sorcerer build. Salvage Legendary Items with higher Aspect values to unlock them in the Codex of Power, and then imprint them onto Legendary Items with the preferred affixes.

Gear Slot	Aspect Name	Legendary Aspect Power
Amulet (+50% bonus effect)	Aspect of the Moonrise	Damaging an enemy with a Basic Skill grants you 4% Attack Speed for 10 seconds, stacking up to 5 times. Upon reaching maximum stacks, you enter a Vampiric Bloodrage, gaining [40 -80%] Basic Skill damage and 15% Movement Speed for 10 seconds.
Ring Slot #1 (replaced by Tal Rasha’s Iridescent Loop)	Rapid Aspect	Basic Skills gain [15 – 30%] Attack Speed.
Ring Slot #2	Aspect of Adaptability	When cast below 50% Maximum Resource, Basic Skills generate 3 of your Primary Resource, once per cast. When cast at or above 50% Maximum Resource, Basic Skills deal [40 – 80%] increased damage.
Wand or Focus	Storm Swell Aspect	You deal x [21 – 30%] increased damage to Vulnerable enemies while you have a Barrier.
Wand or Focus	Aspect of Shredding Blades	Ice Blades’ chance to apply Vulnerable is increased by +20% and the Vulnerable duration is increased by 4 seconds. You gain x [15 – 25%] Vulnerable Damage. Note: Use only for the Vulnerable Damage.
Gloves (replaced by Paingorger’s Gauntlets)	Conceited Aspect	Deal [15 – 25%] increased damage while you have a Barrier active.
Chest (replaced by Raiment of the Infinite)	Aspect of Disobedience	You gain [0.6 – 1.1%] increased Armor for 4 seconds when you deal any form of damage, stacking up to [36 – 66%].
Helm (replaced by Harlequin Crest)	Snowveiled Aspect	Casting Ice Armor makes you Unstoppable and grants 30% bonus Armor for [3.0 – 5.0] seconds.
Pants (replaced by Tibault’s Will)	Aspect of Might	Basic Skills grant 20% Damage Reduction for [2.0 – 6.0] seconds.
Boots (optional replacement withFlickerstep)	Hectic Aspect	After casting 5 Basic Skills, one of your active Cooldowns is reduced by [1 – 2] seconds.

Gems

Listed below are the best Gems to socket into gear for each item type.

Slot	Gems
Weapon	Royal Sapphire for increased Vulnerable Damage.
Armor	Royal Ruby for increased Maximum Life.
Jewelry	Any Resistance Gems needed or Royal Skull for Armor.

Elixirs

Visit the Alchemist in any main town to craft helpful Elixirs that increase stats and experience gain for 30 minutes. Make sure to forage plants and pick up the necessary crafting materials during your adventures; they randomly spawn around the world. Elixirs can also drop randomly from enemies and chests during many activities in Diablo 4. Listed below are the best Elixirs to consume, ranked by importance.

1. Elixir of Precision provides the highest damage output increase, if not already capped at 100% Critical Strike Chance.
2. Elixir of Advantage increases damage output, if not already capped at 100% Attack Speed bonus from gear and Paragon.
3. Elixir of Fortitude is the best general purpose option for survivability. Increased Maximum Life grants larger Barriers from Protection and Ice Armor.
4. Elixir of Iron Barbs can provide a high amount of Physical Damage Reduction. Armor becomes more effective as you approach the Armor cap (9,320 against monster level 100 and above).
5. Specific Resistance Elixirs can be utilized to survive against Uber Bosses with elemental attacks.

Return to the Alchemist again when you reach Level 20, 30, 45, 60, 70, 80 and 90, to upgrade your potion. The extra healing is essential to survival.

Stat Priority and Tempering Affixes

Listed below are the affixes to prioritize on gear for Arc Lash Sorcerers. Each line of affixes are listed in order of importance. Affixes on the same line are considered to be equally important, but their benefits may vary depending how much is stacked or other character stats. Bolded affixes are the most important targets for Masterworking upgrades.

A One-handed Weapon and Focus setup is preferred over a Staff for more beneficial utility affixes and a faster Weapon Speed. If you are utilizing any Lucky Hit effects, such as Ball Lightning Enchantment, equip a Wand. Otherwise, equip a Dagger for increased Damage to Close Enemies on the implicit stat.

The priority order of Resistances is Lightning > Poison > Fire > Cold > Shadow. Maximum Resistance is 70% by default for each element and can be increased to 85% by various sources.

If you are using Tal Rasha’s Iridescent Loop, temper 2 additional sources of elemental damage types from the Elemental Surge Manual onto weapon slots. Cold, Poison, or Shadow damage procs can be utilized to gain the 3rd and 4th Tal Rasha buff stacks. The Tal Rasha buff has a maximum stack limit of 4. Otherwise, there are no other useful tempers in the Weapon category.

If you are using a speed setup with Teleport Enchantment, temper the Evade Cooldown Reduction affix from the Natural Motion Manual onto your Boots and Amulet. Otherwise, temper the Movement Speed or Teleport Cooldown Reduction affixes.

Check the Tempering and Masterworking section for more details on Blacksmith upgrading.

Advanced Information

Additional details are provided in the following sections for a more in-depth explanation of the Arc Lash Sorcerer. Read this advanced information after understanding the basic overview of the build in the previous sections.

Build Mechanics

Playing the Arc Lash Sorcerer is fairly simple, but requires careful management of Cooldowns. Arc Lash deals most of the overall damage output with multiple sources of increased Basic Skill damage, while rapidly activating other Shock Skills with Unstable Currents to supplement additional damage.

Skill Points are allocated into Destructive Charged Bolts, but not actually slotted into the Skill Bar. The 20% reduced enemy damage debuff is applied through auto-casted Charged Bolts through Unstable Currents. Overflowing Energy and Hectic Aspect on Legendary Boots (or Flickerstep) reduces Unstable Currents cooldown, so activate the Ultimate Skill often.

Each cast of Arc Lash has a 25% chance of spawning Lightning Spear while Unstable Currents is active. Lightning Spear counts as a Conjuration Skill to gain increased damage stacks from Conjuration Mastery, and the spear applies Vulnerable on Critical Strike. Lightning Spear can also be casted manually from the Skill Bar to apply Vulnerable when Unstable Currents is not active.

Survivability is achieved through the use of three Defensive Skills, Flame Shield, Ice Armor and Shimmering Teleport. In addition, each Cooldown Skill casted grants a Barrier from Protection. Proper use of these Skills can keep a Sorcerer alive through the toughest battles, despite having a low Life pool.

Damage Rotation

Use the following rotation to optimize damage.

1. Activate Unstable Currents often, as the Cooldown is reduced frequently.
2. Cast Lightning Spear to apply Vulnerable when Unstable Currents is not active.
3. Spam Arc Lash.
4. Use Ice Armor, Teleport and Flame Shield to activate Barriers from Protection.

Telestomp with Raiment of the Infinite

Raiment of the Infinite allows the Arc Lash Sorcerer to use 2 sources of Teleport offensively. Teleporting on top of enemies to Stun and group them up is called “Telestomping”. This playstyle can quickly clear groups of enemies and keep them Crowd Controlled (CC) for safety, perfect for speed-farming Helltides, Nightmare Dungeons, and The Pit!

Use the following setup for the Arc Lash Sorcerer.

• Equip Raiment of the Infinite to enable Telestomps. Target-farm Raiment of the Infinite from Varshan or Lord Zir for the best chances of it dropping.
• Replace Ball Lightning with Teleport in the Enchantment Slots.
• Equip Boots with the implicit effect, Attacks Reduce Evade’s Cooldown, which work with the Evade Teleport. Prioritize the Ranks of Teleport affix.

Tempering and Masterworking

The Season 4 update (Patch 1.4.0) introduces a rework for itemization. Tempering and Masterworking brings the biggest change to itemization since the release of Diablo 4, so make sure you understand the new systems explained in this section.

The amount of affixes on items has been changed to reflect its rarity: Normal Items have no affixes, Magic Items have 1 affix, Rare Items have 2 affixes, Legendary Items have 3 affixes, and Unique Items have 4 affixes. Upgrading a Rare Item to a Legendary Item by imprinting a Legendary Aspect from the Codex of Power will not add a third affix. Therefore, Legendary Items are superior to lower rarity items for a min-maxed character.

Greater Affixes are a newly added mechanic that increases the value of an affix by 50%. Ancestral Legendary Items and Unique Items can now drop with up to 4 Greater Affixes! Search for items with your preferred Greater Affixes to upgrade with Tempering and Masterworking.

Tempering and Masterworking is an important system, even mandatory in the endgame, for character progression. You are able to add 2 additional affixes on any Rare Item or Legendary Item, exclusive to the Tempering System. An Ancestral Legendary Item can have up to 5 total affixes! Unfortunately, Unique Items cannot be tempered to add affixes.

Masterworking uses new crafting materials found in The Pit to further enhance the stats of an item. These upgrades can be applied on an Ancestral Legendary Item that has its Tempering Slots filled out. Unique Items can be upgraded with Masterworking right away, as tempering does not apply to them. Each item has 12 upgrade slots. On upgrade Ranks 4, 8, and 12, a random affix is increased in value by 25%. Every other upgrade Rank applies a 5% increase to all affixes on an item. Attempt to apply the bonus 25% upgrade to your preferred affix multiple times by resetting the Masterworking Ranks to repeat the process.

Obol Gambling

Obol gambling is a great way to potentially find item upgrades or items missing from your build. Use Obols on your target equipment for a chance to receive Greater Affixes. Check out the new tool from Icy Veins for gambling Obols in the link below.
