The Rock Splitter Thorns Spiritborn Build, offers an intriguing mix of defensive and offensive playstyles, leveraging the Spiritborn's Resolve mechanic and the powerful Thorns scaling.

Diablo 4: Rock Splitter Thorns Spiritborn Build Guide

If you're keen on testing this powerful build, keep reading for an in-depth look at Skill Tree choices, stat priorities, Paragon Board allocation, and recommended gear.

How The Rock Splitter Thorns Build Works

The core of the Rock Splitter Thorns Build revolves around the Accelerated perk of the Rock Splitter skill, which applies 100% of Thorns damage on a hit. This means that the build can deal AoE damage to multiple enemies while maintaining a strong defensive barrier. Unlike the typical Thorns builds that focus on being hit, this build's damage output scales effectively without requiring the player to be injured.

Additionally, the build uses other spirit-based skills, such as the Gorilla Spirit, to gain access to powerful passives like Resilient, boosting overall tankiness.

Gear & Affixes for Rock Splitter Thorns Spiritborn

While the build can be quite powerful, it has specific gear requirements to function optimally. The Sepazontec Unique Staff is a key piece for ensuring the build's AoE Thorns scaling, and Runewords such as LithWat and ZolKry are integral for maximizing the build's damage potential.

Runewords & Gems

For Runewords, focus on LithWat and ZolKry. These provide essential bonuses to AoE and Thorns damage scaling. For Gems, use Emeralds in your Armor for Dexterity, and Diamonds in Jewelry to help cap Elemental Resistances.

The ideal roll for each stat is crucial, but even mid-tier rolls can be sufficient to handle high-end content, especially with the Scrolls of Restoration available.

Mercenary & Reinforcement Hires

This build is flexible in terms of Mercenaries, but the following combination will provide a good balance of defense and utility:

Rather: A reliable panic button that offers CC and grants Unstoppable, which is useful in tough situations. His Skill Tree should include:

Ground Slam

Draw Fire

Bastion

Inspiration

Varyana: Known for her Ancient Harpoons ability, she excels at gathering enemies and ensuring your AoE skills hit multiple targets. Set her to trigger when using a Defensive Ability.

Paragon Board & Glyphs

Paragon Board & Glyph Combinations:

Headhunter

Spiney Skin

Viscous Shield

Sapping

Finally, continue leveling all glyphs to 100 in the same order.

Playstyle for the Rock Splitter Thorns Spiritborn

To maximize your damage output, always use your Ultimate Ability (The Hunter) when fighting Bosses or Elites. Use Toxic Skin on cooldown to ensure your Thorns passive is active. Meanwhile, switch between your defensive skills to mitigate incoming damage and keep your Barrier up.

Your Runewords and Binding Morass Aspect will group enemies, so stand still when possible to get the maximum damage output from your AoE.
