Diablo 4 Season 13 & Lord of Hatred Poison Execute Spiritborn Build Crafting Guide: How to get infinite Cooldowns and Pestilent Swarms?

Category: Diablo 4 Posted: May 23, 2026 Views: 14

When it comes to Diablo 4 classes focused on dealing poison damage, Spiritborn is likely the first one that comes to mind right now. While Rogue and Druid are certainly capable of doing so, Spiritborn is undeniably the true master of this craft.

Therefore, if you are looking to utilize poison-centric builds in Season 13 or Lord of Hatred expansion, building around Spiritborn remains your absolute best option.

In this guide, we will introduce you to Poison Execute Spiritborn build, a setup boasting incredibly high farming efficiency, ensuring you can charge through the newly reset game environment with unstoppable momentum!

Diablo 4 Season 13 & Lord of Hatred Poison Execute Spiritborn Build Crafting Guide: How to get infinite Cooldowns and Pestilent Swarms?

Skill setup and related mechanics

The key to crafting this build lies primarily in Counterattack and Rushing Claw skills, as well as The Devourer Ultimate skill.

In particular, you must ensure that your Ultimate skill is available at all times, as it allows you to instantly execute any enemy whose accumulated poison damage exceeds their current remaining healthy.

This means that immediately upon entering any dungeon or event you intend to farm, you should trigger all available cooldown reset effects, and then activate Rushing Claw to dash furiously through the area.

This sequence causes all enemies in your path to instantly suffer massive amounts of poison damage, leading to their immediate execution.

From there, you simply need to keep refreshing your skill cooldowns, ensuring The Devourer remains ready to use, to clear the dungeon with ease.

A crucial point to note is that as soon as The Devourer finishes its cooldown, you must cast it again immediately; furthermore, while moving through the battlefield, ensure that its active buff effect remains uninterrupted at all times.

Additionally, Rushing Claw has the ability to extend the duration of all your other active skills. This means that whether it is your core Counterattack buff or various other beneficial effects, they will persist for a longer period as you dash through the dungeon.

Building upon the core mechanics described above, if you find yourself facing a boss encounter, simply activate The Devourer, Toxic Skin, Counterattack, and Ravager in succession, then proceed to dash back and forth across the battlefield.

The only additional adjustment required for boss fights is to switch the minor upgrade for The Devourer from Instant Kill (the execution effect) to Poisoning Duration in order to maximize your total damage output.

How to cast Rushing Claw continuously?

This skill has now been reclassified as an Eagle skill, which means it no longer requires a specific target to be cast. To further reduce this skill's cooldown beyond the base level, you must accumulate a full stack of 4 Ferocity charges.

To achieve this, you need to unlock Ravager node in your Skill Tree and level it up to rank 20 or higher.

If the skill's rank falls below 20, it can provide a maximum of only three Ferocity charges. In such cases, you also have the option to buy Diablo 4 items on IGGM to utilize gear that grants an additional +1 skill level.

How to reset skill cooldowns?

To accomplish this, you must first unlock Prodigy's Tempo Paragon node. With this node active, every time you cast the same Core or Mastery skill three consecutive times, the cooldowns of all your skills currently on cooldown will be reduced by 30%.

Subsequently, you can choose to acquire Menagerist glyph, which grants you a 4% bonus to damage whenever you use any Bat, Jaguar, Eagle, or Centipede skills.

Other glyphs and nodes worth unlocking include:

  • Consumption
  • Colossal
  • Drive
  • Canny
  • Bane

Which gear pieces are the best choices?

Once you have selected Exalted Devourer upgrade for your The Devourer skill, any non-boss enemies you attack that are currently afflicted by poison will instantly die, releasing a Pestilent Swarm that deals damage to any enemies it passes through.

If you wish to have this highly beneficial effect constantly active around you, you can achieve this by acquiring Ring of the Writhing Moon, a Legendary Ring.

This piece of gear causes a Pestilent Swarm to emanate from your character every four seconds, dealing poison damage with every hit.

However, the best way to obtain this ring is to farm the boss, Lord Zir. To do so, you must first acquire Lair Keys, which are required to unlock his loot cache once the battle concludes.

Fortunately, IGGM Diablo 4 Facebook Group is currently hosting a giveaway for Lair Boss Keys! In addition to Lair Keys, you also have the chance to win three other types of keys, allowing you to unlock even more hoards and acquire even more rare gear!

Now, back to the main topic. Upon acquiring this ring, it is highly recommended to ensure it possesses affixes related to DoT, poison damage, and vulnerable damage for optimal effectiveness.

Next, your second ring should also feature the same multiplicative damage affixes found on Ring of the Writhing Moon; additionally, you must imprint Aspect of Pestilence onto it.

The effect of this Aspect is to increase the damage dealt by Pestilent Swarm by 100% and extend its duration by 50%, causing it to spiral outward.

The final key damage buff comes from imprinting Aspect of Supremacy onto your Amulet. Whenever your Ultimate Skill is active, this Aspect grants you one stack of the supremacy buff for every enemy you kill.

Each stack of this buff increases your damage by 11.7%, stacking up to a maximum of 117%. Once your Ultimate Skill's effect ends, you immediately gain 5 stacks of the buff, though you will subsequently lose one stack per second.

To fully capitalize on this aspect's effect, you must constantly ensure that your Ultimate Skill, The Devourer, remains active. In fact, this is a point we have repeatedly emphasized throughout our discussion of the skill set.

Charm setup

If you have unlocked Lord of Hatred expansion, you can further enhance your build by equipping Protean Heart Charm.

Whenever you cast a skill belonging to a different base spirit category, this charm causes your damage bonuses to shift to that new category while simultaneously boosting your core stats by 100%.

That concludes our guide for this time. If you are currently playing a character in Spiritborn class, why not give this build a try?
