The Giga-Speed Spiritborn Evade Build for Diablo 4 Season 9 (Sins of the Horadrim) is a high-mobility, high-damage endgame build that leverages the Eagle Spirit Hall and the Evade mechanic to deliver rapid, devastating attacks via Storm Feathers and Thunderspike. This build is designed for players who enjoy a fast-paced, agile playstyle, capable of clearing high-level content like Nightmare Dungeons, The Pit, and Tormented Bosses with ease. Below is a comprehensive guide based on the latest available information for Season 9.

Overview

The Evade Spiritborn build focuses on:

• Infinite Evade: Using Thunderspike and specific gear to reset the Evade cooldown, allowing near-constant dodging.
• Storm Feathers: Generated by Evade through the Eagle Spirit Hall, these deal massive Lightning damage and apply Vulnerable to enemies.
• High Mobility: The build emphasizes speed, enabling players to zip through content and farm efficiently.
• Survivability: Combines high dodge chance, Unstoppable effects, and defensive skills like Armored Hide for tankiness.

This build is considered one of the fastest and most powerful Spiritborn setups, excelling in both AoE and single-target damage.

Core Mechanics

The build revolves around:

1. Eagle Spirit Hall: Casting an Eagle skill grants a 4-second Storm Feathers Movement Speed bonus. When you Evade, you fling up to 8 Storm Feathers per remaining second, each dealing 125% Lightning damage and applying Vulnerable for 5 seconds. All skills become Eagle skills.
2. Thunderspike: Every third cast reduces Evade’s cooldown by 5 seconds, enabling near-infinite Evade with proper gear and runes.
3. Sepazontec (Unique Quarterstaff): Enhances Basic Skills (like Thunderspike) by increasing damage by 25-75%, always using the third attack, and triggering triple strikes every third attack, amplifying damage and cooldown reduction.
4. Storm Feathers: The primary damage source, triggered by Evade, scales with Dexterity, Eagle Skill Potency, and Storm Feather Potency on gear.

  • Enhanced Soar: Improves mobility.

• Secondary: Jaguar (increases Ferocity stacks for more damage) or Gorilla (adds barriers for extra defense).

Gear and Stats Priority

Key Uniques

• Sepazontec (Quarterstaff): Essential for infinite Evade. Farm from Duriel or Andariel on the Boss Ladder or gamble with Murmuring Obols at the Purveyor of Curiosities.
• Harlequin Crest (Helm, Mythic Unique, Optional): Provides cooldown reduction for Evade and boosts overall damage.
• Sunbird’s Gorget (Amulet, Optional): Creates a Firestorm when picking up Storm Feathers, dealing additional Fire damage. Best for a hybrid Firestorm variant.

Recommended Gear Affixes

• Boots: Attacks Reduce Evade’s Cooldown by x Seconds (critical for infinite Evade).
• Weapon: Dexterity, Critical Strike Damage, Storm Feather Potency.
• Armor: Armor, Movement Speed, Cooldown Reduction, Vigor Cost Reduction.
• Jewelry: Critical Strike Chance, Maximum Vigor, Resistance to All Elements.

Legendary Aspects

• Aspect of Unyielding Hits (Gloves): Increases damage based on Armor (aim for 5000+ Armor).
• Aspect of Disobedience (Pants): Boosts Armor and survivability.
• Aspect of Falling Feathers (Amulet): Enhances Storm Feather damage.
• Aspect of Recalling Feathers (Chest): Boosts Sunbird’s Gorget Firestorm damage (if used).

• Recommended: Cosmic Anomaly (steady Arcana flow), Thunderous Particle (negates Suppressor affixes), Fractured Core (counters Damage Resistance Aura Champions).

Runewords

Runewords replace gems and enhance the build’s mechanics. Equip up to two pairs:

1. Cem + Lum (Helmet): Evade regenerates Vigor, ensuring constant casting.
2. Cir + Gar (Pants): Casting the same spell (Thunderspike) three times boosts Critical Strike Chance.
3. Alternate Options:
   • Cem + Jah: Increases mobility (“zoomies”).

• Bac + Zec: Ensures permanent The Seeker uptime.
• Moni + Qax: Massive damage boost for Jaguar skills (if using Jaguar secondary).

Paragon Boards and Glyphs

By Paragon 200, you should unlock all major nodes and glyphs. Key boards and glyphs include:

• Starting Board: Focus on Dexterity and Movement Speed.
• Eagle Board: Boosts Storm Feather damage and Eagle skill potency.
• Glyphs:
  • Colossal: Increases Armor for Aspect of Unyielding Hits synergy.
• Fulgur: Boosts Lightning damage.
• Advantage: Enhances Critical Strike Chance.
• Progress through The Pit to rank up glyphs (radius increases at levels 15 and 46).

Mercenaries

• Primary: Subo – Uses traps to slow enemies and apply Vulnerable, synergizing with Storm Feathers.
• Reinforcement: Raheir with Bastion + Inspiration for extra tankiness and Field of Languish for crowd control.

Gameplay Loop

1. Engage: Use Vortex (if available) or Soar to group enemies.
2. Spam Evade: Trigger Storm Feathers to deal Lightning damage and apply Vulnerable.
3. Weave Thunderspike: Every third cast reduces Evade’s cooldown, maintaining infinite Evade.
4. Use Armored Hide: On cooldown for Unstoppable and Block Chance.
5. Cast Scourge: For crowd control and healing against large packs.
6. The Seeker/The Hunter: Maintain buffs for damage and Ferocity stacks.
7. Pick Up Storm Feathers: If using Sunbird’s Gorget, this triggers Firestorm for extra damage.

Gear Progression

• Early Game (Level 15-60): Focus on boots with Attacks Reduce Evade’s Cooldown and prioritize Dexterity, Vigor, and Cooldown Reduction. Use Quill Volley until Thunderspike weaving is smooth.
• Endgame (Torment 1+): Farm Sepazontec from Duriel/Andariel or Obol gambling. Imprint Aspects from the Codex of Power and socket Horadric Jewels.
• Min-Max: Target 5000+ Armor for Aspect of Unyielding Hits, max out Critical Strike Chance/Damage, and optimize Storm Feather Potency.

Season 9: Sins of the Horadrim

• Horadric Spells: Craft using Arcana from Nightmare Dungeons. Use Cosmic Anomaly and Thunderous Particle to counter enemy affixes.
• New Gems: Socket Horadric Jewels in jewelry for build synergy.
• No Mythic Uniques Required: The build is viable without Harlequin Crest, making it accessible.

Tips and Notes

• Leveling: Start with a Quill Volley Leveling Build until Level 15, then respec to Evade Spiritborn after unlocking Eagle Spirit Hall.
• Survivability: With 80%+ dodge chance and near-100% Block Chance from Armored Hide, this build is extremely tanky.
• Nerfs: Despite nerfs in Season 6, the build remains viable for Pit 100 and Tormented Bosses like Uber Lilith.
• Farming: Use this build for speed farming Nightmare Dungeons and The Pit due to its mobility and AoE clear speed.
