Arc Lash Endgame Sorcerer Build for Diablo 4 (Season 1)

Lightning Stun Build with Unstable Currents

The Arc Lash Sorcerer build is a game-changer for Diablo 4 players seeking a simplified gameplay experience. By primarily spamming the Basic Skill, Arc Lash, players can rapidly activate other Lightning Skills with Unstable Currents and Stable Aspect, engulfing the screen in an electrifying display. The Glinting Arc Lash and Overflowing Energy skills reduce cooldowns, ensuring the entire arsenal of Skills is always ready for action.

Survivability is a crucial aspect of the Arc Lash Sorcerer build. To keep the Sorcerer alive through tough battles, four Defensive Skills are utilized: Flame Shield, Ice Armor, Frost Nova, and Shimmering Teleport. Despite having a low Life pool, proper use of these Skills can turn the tides of battle in favor of the player.

The Arc Lash Sorcerer build is known for its “shockingly stunning” performance in all endgame activities. This build is not only effective but also caters to players who prefer a simple yet powerful melee playstyle.

Note: This endgame build guide assumes that your character is at least level 50. If you need assistance reaching that level, refer to the Sorcerer Leveling Guide.

Season of the Malignant

Season 1 Patch Updates

The Season 1 Patch Update brings several changes specific to the Arc Lash Sorcerer build. Here’s an overview of the updates:

• Devouring Blaze bonus Critical Strike damage reduced from 10/20/30% to 7/14/21%.
• Devouring Blaze bonus Critical Strike damage to Immobilized reduced from 25/50/75% to 10/20/30%.
• Aspect of Retribution bonus damage to Stunned reduced from 20-40% to 10-20%.
• Aspect of Disobedience maximum stacks reduced from 100 to 60, resulting in a reduction of the maximum Bonus Armor % from 25%-50% to 15%-30%.
• Protection Barrier duration increased from 2 to 3 seconds.
• Mana Shield Damage Reduction increased from 5/10/15% to 7/14/21%.
• Destruction Glyph now affects all damage instead of just Core Skills.

These changes have caused a noticeable decrease in the Arc Lash Sorcerer’s damage output. However, the inclusion of Destruction in the Paragon setup may help the Arc Lash build maintain its viability in Season 1.

Best Malignant Hearts Tier List for Arc Lash Sorcerer

The Season 1 theme introduces Malignant Hearts, which offer build-altering bonuses. Malignant Hearts are divided into four categories, each with a corresponding color that needs to be socketed into equipped jewelry. It’s important to always socket Malignant Hearts instead of a Skull in Jewelry, as they provide an Armor bonus that scales with their Item Power.

Here’s the Malignant Heart Tier List for the Arc Lash Sorcerer build, ranked by importance. The displayed stats reflect what a level 20 character would receive from a drop.

1. Caged Heart of The Barber (Wrathful, Super-World Tier III): Absorbs Critical Strikes and subsequent damage within 2.0-4.0 seconds, which erupts onto surrounding enemies. Stored damage increases by 10% per second. – Fixed in Patch 1.1.1 to work with “on hit” effects and Lucky Hit chance.
2. Caged Heart of Tal’Rasha (Vicious, Offensive): Deals 7-12% increased damage for 3-10 seconds for each unique element you damage with. – Fixed in Patch 1.1.2 to be correctly calculated as multiplicative instead of additive.
3. Caged Heart of Revenge (Brutal, Defensive-World Tier III): Suppresses 10-20% of incoming damage, amplifying and exploding the suppressed damage by 250% when a Defensive, Subterfuge, or Macabre skill is used, dealing up to 1360-2040 Fire damage to nearby enemies.
4. Caged Heart of Spellbreaking (Brutal, Defensive): Grants 10-20% Damage Reduction for 5 seconds upon taking Elemental Damage. – Buffed in Patch 1.1.1 to reduce all damage taken, instead of providing resistances to individual elements.
5. Caged Heart of Tempting Fate (Vicious, Offensive-World Tier III): Increases Critical Strike Damage by 40-60%, but reduces Non-Critical Strikes’ damage by 20-15%.
6. Caged Heart of the Picana (Vicious, Offensive): Charges enemies for 0.75-2.50 seconds with Critical Strikes, causing lightning to arc between them and any other charged enemies, dealing 68-136 Lightning damage.

Skill Tree Points and Skill Bar

The following tables illustrate the allocation of Skill Points for the Arc Lash Sorcerer build. The first table presents the most important 48 points to start the build, while the second table provides the remaining 10 points that should be allocated once you obtain all Skill Points from Renown.

Enchantment Slots

This Basic Attack build utilizes Fire Bolt in the first Enchantment Slot to activate Burning bonuses from Devouring Blaze and Paragon. In the second Enchantment Slot, Ball Lightning is used due to its high AoE damage output.

Hardcore players may consider using Flame Shield as an alternative option, as it provides cheat death functionality with a 120-second cooldown.

Paragon

The Paragon progression system unlocks after reaching Level 50 and offers a significant boost to character power. Within the Paragon Board, various bonuses can be obtained, ranging from minor stat enhancements on Magic Nodes to more substantial gains with Rare Glyphs and Legendary Nodes.

When progressing towards Glyph Sockets and Legendary Nodes, it’s recommended to prioritize attributes such as Attack Speed, Non-Physical Damage, Intelligence, Resistance, and Life for Normal and Magic Nodes. As Glyphs level up, their effects expand in radius. If you’re unable to meet Additional Bonus requirements early on, it may be better to skip allocating extra nodes for the time being.

Mechanics and Playstyle

Playing as an Arc Lash Sorcerer is fairly simple but requires careful management of cooldowns. The primary source of damage comes from spamming Arc Lash, while Unstable Currents activates additional Lightning Skills. Skill Points are allocated into Ball Lightning and Charged Bolts but are not actually slotted into the Skill Bar. Glinting Arc Lash and Overflowing Energy reduce the cooldown of Unstable Currents, making it crucial to use the ultimate skill frequently.

Damage Rotation

Use the following rotation to optimize damage output:

1. (Optional) Against large packs of enemies, tough elites, or bosses, activate Unstable Currents. This Ultimate Skill should be used often, as the cooldown is reduced frequently.
2. Cast Frost Nova to apply Freeze and Vulnerable.
3. Spam Arc Lash.
4. Use Ice Armor, Teleport, and Flame Shield when necessary to stay alive.

Gear Choice and Stat Priority in the Endgame

During farming sessions with the Arc Lash Sorcerer build, ensure that you pick up all Rare Item drops that may serve as upgrades. Additionally, save Legendary Items with useful aspects in your stash for later use or extraction to imprint them onto well-rolled Rare Items.

It is preferred to use a Wand and Focus weapon setup over a Staff. The faster Attack Speed and Lucky Hit Chance implicit synergize well with this Basic Attack build. Make sure to replace outdated gear frequently and upgrade new gear at the Blacksmith to increase Item Levels further for higher stat values.

Stat Priority List

Listed below are the affixes to prioritize on gear for Arc Lash Sorcerers. Each line of affixes is listed in order of importance. Affixes on the same line are considered equally important, as their exact values differ for each character. Intelligence and additive damage increases have an effect dependent on the amount already stacked. Bolded stats are the most important and sometimes vital for the build to function properly.

• (+ DPS value), Critical Strike Damage, Lightning Critical Strike Damage, Vulnerable Damage
• (+ DPS value)
• Basic Attack Speed, Cooldown Reduction
• Critical Strike Chance
• + Basic Attack Speed, Cooldown Reduction
• + Attack Speed, Critical Strike Chance, Lightning Critical Strike Damage
• + Ranks of Ball Lightning
• + Ranks of Devouring Blaze Passive
• (+ Critical Strike Chance), Critical Strike Damage, Lightning Critical Strike Damage, Vulnerable Damage

Legendary Aspects and Codex of Power

Listed below are the best-in-slot Aspects found on Legendary Items that are important for the Arc Lash Sorcerer build. Aspects from the Codex of Power can be used if you cannot find the proper Legendary drops, but they have weaker effects. Extract Aspects from lower-level Legendary Items and imprint them onto better Rare Items with preferred stats.

Unique Items

Raiment of the Infinite

• Raiment of the Infinite – After using Teleport, close enemies are pulled towards you and stunned for 2-3 seconds, but Teleport’s cooldown is increased by 20%.

This Unique Chest Armor can be used to group enemies, allowing Arc Lash to hit them all.

Esu’s Heirloom

• Esu’s Heirloom – Your Critical Strike Chance is increased by 15-25% of your Movement Speed bonus.

These Unique Boots provide a decent amount of Critical Strike Chance when stacking Movement Speed. Flickering Arc Lash can be swapped for additional effect.

Gems

Listed below are the best Gems to socket into gear for each slot type:

• Weapon: Royal Emerald for Critical Strike Damage to Vulnerable enemies.
• Armor: Royal Ruby for Maximum Life or Royal Topaz to prevent deaths from chain Crowd Controls.
• Jewelry: Malignant Hearts for Season 1. Otherwise, Royal Skull for Armor.

Elixirs and Health Potions

Visit the Alchemist in any main town to craft helpful Elixirs that increase stats and experience gain for 30 minutes. Ensure you forage plants and collect the necessary crafting materials during your adventures, as they randomly spawn around the world. Craft a Precision Elixir for Critical Strike Chance and Damage or an Assault Elixir for Attack Speed.

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