The Spiritborn's "Poison CRUSH" build is not only a strong option for Season 9 in Diablo 4; it is a strategic masterpiece crafted for seamless mastery of Torment 4. This guide will explore the details, assisting you in refining your approach and helping you understand why this build is celebrated for its "EASY T4" potential.

Optimizing your Diablo 4 Items is crucial. For weapons, look for those with high base poison damage or implicit modifiers that enhance damage over time. Armor pieces should focus on defensive stats such as Total Armor, Damage Reduction, and resistances, while also seeking rolls that boost Poison Damage or Willpower, which often synergizes with Spiritborn abilities.

At its core, the "Poison CRUSH" build centers around several key Spiritborn skills. Consider skills like "Venomous Spines," which allows for rapid poison application, alongside "Plague Cloud," that disseminates corrosive mist among groups of enemies. The "CRUSH" element likely derives from a powerful ultimate or a synergistic skill like "Toxic Burst," which detonates all existing poisons on enemies for substantial immediate damage, effectively transforming your damage-over-time into burst damage.

Amulets and rings serve as prime locations for legendary aspects that enhance your poison output, such as those that increase damage against poisoned enemies, extend poison duration, or provide resource generation upon poison application. Be on the lookout for specific Spiritborn Unique Diablo 4 items that may offer transformative bonuses, such as an explosive poison nova or significantly reduced cooldowns on your burst abilities.

Your Paragon Board strategy should aim to maximize poison damage, damage over time, and damage reduction nodes. Glyphs that improve Poison Damage, Willpower, or provide a flat damage multiplier to poisoned targets are vital. Additionally, do not overlook defensive glyphs, as survival in T4 is as critical as dealing damage.

The playstyle is straightforward: begin combat with your primary poison skills, ensuring that multiple enemies are affected. Once a sufficient number are poisoned, unleash your "Toxic Burst" or equivalent "CRUSH" ability to trigger the accumulated damage, often eliminating entire groups in a single blow.

With the appropriate setup of New Legendaries items  and a fundamental understanding of its potent poison mechanics, the Spiritborn "Poison CRUSH" build will enable you to effortlessly overcome every challenge Torment 4 presents in Season 9.
