Diablo 4 Season 9: Rock Splitter Thorns Spiritborn Build Guide
If you're looking to Diablo 4 Items dominate Diablo 4 Season 9's endgame with almost absurd power, the Rock Splitter Thorns Spiritborn build is your go-to choice. Built around stat double-dipping and a broken synergy with Jaguar Spirit, this build takes advantage of Thorns damage in a way that shreds anything in your path. Thanks to a few glitchy mechanics, it's one of the most overtuned setups in the game-and yes, it might get nerfed, but while it's live, it's time to capitalize.
This guide will walk you through everything you need to know to play and Diablo 4 Items gear your Thorns Spiritborn for max efficiency.
Why Is Rock Splitter Thorns Spiritborn So Strong?
At the core of this build is Rock Splitter, a fast-hitting ability that triggers Thorns damage on each hit, especially when paired with Sepazontec, Razorplate, and Loyalty's Mantle. With the Double Jaguar Spirit Hall bonus, you're essentially stacking ferocity, attack speed, and Jaguar ability bonuses multiple times, giving your Thorns insane scaling.
The reason this works so well is a form of stat double-dipping, where Thorns modifiers are unintentionally applied multiple times. That's especially broken when combined with Ravager, which applies damage and status frequently, and Nebulous Extract, which turns your abilities poisonous and synergizes with passive Thorns procs from Replenishing Toxic Skin.
