Boulder Druid Endgame Guide

Season 2 - Blood

Share on Social

Welcome to the Boulder Druid Endgame Guide for Diablo 4! This build is all about casting as many Boulders as possible, which rotate around your Hurricane and rip enemies apart in a vortex style area of effect. In Diablo IV, the Boulder Druid closely resembles the classic Hammerdin from Diablo II, making it the closest equivalent in the game to that iconic character. It revolves around Dolmen Stone, which enables this unique playstyle, and Metamorphic Stone which converts Boulder into a Core Skill.

Without Dolmen Stone, Symbiotic and Metamorphic Stone, the final build is not functional. Make sure to acquire them before transitioning to this build.

Once you acquire the core items, the gameplay is straightforward. Cast Hurricane then start spamming Boulder to deal Damage and reset the Cooldown of Hurricane thanks to Symbiotic and Nature's Fury. Use Blood Howl to gain Attack Speed and Heal yourself. Cast Petrify defensively against dangerous threats or offensively to gain a massive multiplier to your Critical Strikes. the Umbral is amazing to refill your Spirit passively via the constant Knockbacks from Boulder and the Slow from Hurricane. Weave in Wind Shear at least every 4 seconds to keep all of your Buffs up and Trample as well for Spirit Generation or to rapidly move to another position.

In this guide we teach you everything you need to know to be successful with the Boulder Druid in Diablo 4. Let's get to it!

Season 2 - Season of Blood

Completing the seasonal questline, partaking in the seasonal Blood Harvest event and collecting Potent Blood are the main ways of obtaining and empowering these abilities. Check out the full Season 2 Guide from Chewingnom to learn more! Helms & Boots can have up to 3 Pacts, Pants can have up to 4, Chests & Gloves can have up to 5 giving you 20 Pacts to empower.

Best-in-Slot Vampiric Powers

  1. Ravenous - A massive Attack Speed multiplier. This build is able to get very close to the Movement Speed cap, making the Ravenous Power super valuable.
  2. Metamorphosis - This Power provides a consistent source of Unstoppable, deals moderate damage, and is your main source of applying the Vampiric Curse. It is an excellent way to keep Ghostwalker active.
  3. Prey on the Weak - The damage bonus is solid, but when used in conjunction with other Vampiric Powers that can inflict a Curse, this Power provides a steady and reliable source of Vulnerable.
  4. Moonrise - This Power scales both your Attack Speed and Movement Speed. A single cast of Wind Shear is often enough to hit 5 targets, giving us full benefits easily.
  5. Undying - This Power is your most reliable source of healing. It makes face tanking most content a breeze.

Alternative Vampiric Powers

  1. Sanguine Brace - Great defensive tool for generating Fortify, this Vampiric Power also gives you increased Critical Strike Chance when Fortified.
  2. Domination - Thanks to Petrify, you can benefit from the multiplier granted by this Power. This also applies to Staggered Bosses.
  3. Resilience - An all-around solid defensive option

Skill Tree & Gameplay

Your general gameplay rotation goes like this: Activate Hurricane and Blood Howl then spam Boulder to have them rotate around Hurricane. Move around to position yourself so they hit enemies. Keep using Blood Howl and Hurricane on Cooldown. Use Trample and Wind Shear to recover Spirit when in need. For the most part, your Spirit should stay up thanks to your CC effects and the Umbral. Use Petrify when in need of extra Damage or use it Defensively.

Active Skills

  • Boulder is your main damaging Skill and Spirit Generator thanks to its Knockbacks and the Umbral.
  • Hurricane makes your Boulder rotate around in the vortex. It also provides great utility by slowing down enemies, reducing their damage, and filling up your Spirit thanks to the Umbral.
  • Wind Shear generates Spirit at range and provides Movement Speed, a source of Vulnerable, and Damage Reduction when using Might. It also activates Moonrise easily.
  • Petrify is both defensive and offensive. Its ability to Stun in a huge AoE is great defensively, while the Critical Strike Damage multiplier it provides is excellent offensively.
  • Blood Howl's Attack Speed bonus allows us to get out as many Boulders as possible. It also serves as a reliable Heal since its Cooldown resets with kills.
  • Trample serves as our Movement ability. It also gives a good amount of Spirit on cast.

Passives

  • Nature's Fury enables Symbiotic to reset the Cooldown of Hurricane. It also lets you proc the other Core Storm Skills by casting Boulder.
  • Once you have Tempest Roar, a single point in Toxic Claws enables you to consistently Crowd Control mobs with Neurotoxin, activate Envenom's damage bonus, and benefit from both Damage to and Damage Reduction from Poisoned enemies.

Spirit Boons

Druids can choose 5 out of 16 Passive bonuses (Boons) from 4 different spirits. You have to bond with one of the Spirits in Túr Dúlra to activate two of its Boons. The remaining Spirits can only have one Boon each. Use the following Boons:

  • Deer Spirit: Wariness for additional defense where we need it most.
  • Eagle Spirit: Swooping Attacks provides Attack Speed, improving your damage as well as healing thanks to more casts per second.
  • Wolf Spirit: Bolster is preferred, as other options provide little to no benefits.
  • Snake Spirit: Obsidian Slam provides a little bit of extra damage.

Bond with the Eagle Spirit and activateScythe Talons for additional Critical Strike Chance.

Resource & Cooldown Management

Managing your Resources is easy with this build.

Resource Aspect of the Umbral

With a good roll of this Aspect, resource management becomes a walk in the park. Thanks to your many Knockbacks from Boulder and Trample, as well as Slow from Enhanced Hurricane and Neurotoxin, your Spirit constantly fills up. On top of that, Petrify also provides another method of gaining Spirit thanks to its Stun.

Cooldown Reduction

Your goal is to require only one activation of Symbiotic to have permanent uptime on Hurricane. A good roll on Dolmen Stone helps a lot, and the rest comes from your Gloves. If needed, an explicit roll on your Totem is an option. Assuming a perfect Symbiotic, make sure the Cooldown on Hurricane is less than 13 seconds. The required amount of Cooldown required is over 35%, but since not all stats show up on your character stat sheet, looking at the Cooldown value on Hurricane is preferred.

Spirit Cost Reduction

Getting this Affix on your Boots and Totem helps a lot especially vs Bosses where the Umbral is close to useless. You also benefit from the Legendary Paragon Node Inner Beast so long as you Shapeshift every 5 seconds.

Resource Generation

Getting this Affix on your Rings and possibly Totem helps refilling your Spirit especially vs Bosses where the Umbral is close to useless.

Tempest Roar

You gain a small amount of Spirit on Lucky Hit with your Storm Skills with this Unique Helm. By casting Boulder, you proc Storm Skills thanks to Nature's Fury.

Paragon Board

Carefully check your Paragon Boards to ensure correct board rotation. Glyphs go from a radius of 3 to 4 when they reach level 15!

  • If you've yet to acquire Tempest Roar, the Heightened Malice Paragon Board provides very little value. You need enemies to be Poisoned reliably to get the best benefits from this Paragon Board. Consider using Poison Creeper instead of Blood Howl, and take the Packleader Wolf Spirit Boon in the meantime.
Boulder Druid Endgame Build Paragon Board

Level the Paragon Board by scrolling. Each step optimizes progression.

Glyphs

We need to level up our Glyphs to increase their power and activate their Additional Bonus with surrounding nodes. Glyphs have a radius of 3 by default, this increases to 4 at Glyph level 15. Complete Nightmare Dungeons to obtain Glyph experience.

Note that there are some Glyph position swaps and a few adjustments to surrounding Paragon nodes once they reach level 15. See the last two steps in the Paragon progression above for details. The setup displayed by default is the final version of the build.

Endgame Gear & Skill Progression

When you start diving into the Endgame, you don't have all the tools available to achieve the final version of the build. Let us guide you through different progression points to give you a smooth transition from our Leveling Guides to the final build.

Progression Goals

Many of your Skill choices depend on what Legendary Aspects and Unique items are available to you. While we can guarantee that everyone has access to the same Codex of Power Aspects, the progression might be different for everyone!

  1. You must have access to Symbiotic, Metamorphic Stone and Dolmen Stone to start playing this build.
  2. Unlock the following Aspects from Dungeons:
  3. Find the following Legendary Aspects either as a random drop or by gambling with Obols:
    • Symbiotic: Gamble Boots.
    • Accelerating: Gamble Totems.
  4. Acquire the following Unique items either as a random drop or by farming specific Boss drops.
    Note: You cannot gamble Unique items with obols!

Learn more details and how to farm Legendary Aspects and Uniques in our General Farming Guide.

Progression Steps

Follow the build's gearing progression from level 50 to 100, including the changes that need to be made as you obtain Legendary Aspects and Uniques.

Note: This build does not have a Starter variant since it requires Endgame items and Aspects.

Early Endgame
Endgame
Speedfarming
Nightmare Dungeon Push
Pinnacle Boss
Abattoir of Zir

Since Dolmen Stone and Symbiotic Aspect are required for the build to function, there is no Starter setup.

In this setup, you have access to all Legendary Aspects, allowing you to pilot a much stronger version of this build. Additional Legendary Aspects are used to fill slots that may be replaced with Unique items later on.

Gear

  • Use Ballistic Aspect on your Helm as a placeholder for Tempest Roar.
  • Aspect of Disobedience greatly helps your survivability by increasing your Armor significantly.
  • Symbiotic Aspect is mandatory to reset the Cooldown of Hurricane with your Boulder casts.
  • Aspect of Might provides easy uptime on Damage Reduction.
  • Ghostwalker Aspect increases your Movement Speed but also Attack Speed thanks to Ravenous. On top of that, the ability to move freely through enemies is excellent not only defensively, but against monsters with big hitboxes like World Bosses, you can get your Boulders to constantly hit by going inside of their hitbox.
  • Aspect of Metamorphic Stone is the bread and butter of the build. It significantly increases the damage of Boulder and removes its Cooldown, allowing you to spam it.
  • Aspect of Natural Balance provides another damage multiplier that is easy to maintain.
  • Aspect of the Umbral refills your Spirit easily thanks to your multiple sources of CC.
  • Aspect of Retaliation provides another significant damage multiplier.
  • Try to get as much Damage to Crowd Controlled Enemies on your Weapon and Rings as possible. This will improve your damage multiplier from Earthen Devastation.

Skills

Until you obtain Tempest Roar, you aren't able to reliably benefit from the damage increase provided by Envenom. Instead, get some more tankiness with Heightened Senses.


The last point is flexible. Put it in Abundance to generate more Spirit, which helps against Bosses.

Another option without Tempest Roar is to use Poison Creeper instead of Blood Howl, and take Packleader Spirit Boon in the meantime.

No Changes

There are no changes to the Gameplay and Spirit Boons.

Hardcore Adjustments

Hardcore requires you to build into more defenses. Here are some tips to successfully navigate this build through potentially dangerous situations:

  • Use Debilitating Roar instead of Trample. Use it wisely to mitigate a good chunk of damage.
  • Careful around Suppressor Elites. Look out for bad combinations with this Elite Affix.
  • Choose Iron Feather on the Eagle Spirit instead of Scythe Talons.
  • Focus more on your Chest & Pants while gearing up. Make sure to have only defensive stats on these two slots as they provide a ton of survivability. Not using Ranks to Boulder on Pants is an option.
  • Use a defensive Paragon Board with a focus on Armor and % Life.
  • Save your Petrify for defensive situations.
  • Use Resilience instead of Ravenous or Moonrise for more survivability.

Build Scaling & Stat Priorities

Learn about the important build scaling mechanics and stat weights.

Damage
Defense
  • Spirit: More Spirit means more casts of Boulder. Tempest Roar, Resource Aspect of the Umbral, Inner Beast, Spirit Cost Reduction and Ressource Generation all contribute. Reclamation also helps, especially if you don't have a well rolled Aspect of the Umbral.
  • Cooldown Redution: Reducing the Cooldown of Hurricane to the point where only one activation of Symbiotic Aspect lets you have permanent uptime means for a generally smoother gameplay experience as your Boulders have much less risk of falling off if you are unlucky with procs.
  • Attack Speed: Acts as a multiplier for your damage by enabling you to cast Boulders faster and stack more of them around your Hurricane. In Season 2, stacking Movement Speed also increases your Attack Speed thanks to Ravenous.
  • Critical Strikes: This build reaches a high Critical Strike Chance. Make sure to get it on Rings, Gloves, and your Totem. Add to that Scythe Talons, Predatory Instinct and the massive increase from Natural Boulder. Sanguine Brace is also an option to push this stat even further.
  • Vulnerable: You get Vulnerable procs from the Exploit Glyph. In Season 2, you can additionally activate and bolster the damage of Vulnerable using Prey on the Weak and Metamorphosis . Though not as powerful as it once was, this multiplier is still fairly convenient to activate.
  • Earth/Nature/Core: Any modifier affecting these tags will increase your damage output. Keep in mind that you do not benefit from the Wrath tag since Boulder gets converted to a Core Skill. It does not benefit from the Wrath Skill Ranks from Dolmen Stone.
  • Crowd Control: Thanks in part to constant Knockbacks from Boulder and Slows from Enhanced Hurricane, you have consistent CC. Damage affixes that deal extra damage against Crowd Controlled or Slowed Enemies are a great alternative way to increase your damage output. Not to mention Earthen Devastation which benefits greatly from damage vs Crowd Controlled.
  • Envenom: We're able to take advantage of this powerful offensive passive thanks to ‍Toxic Claws, which Poisons enemies whenever we deal Critical Strike Damage to them with Storm Skills which we proc from using Boulder in combination with Nature's Fury.
  • Heightened Malice: A massive damage multiplier that you benefit from so long as there are 3 Poisoned enemies around.
  • Ancestral Guidance: Thanks to the high Spirit cost of Boulder you have permanent uptime of this multiplier.

Summary

The Boulder Druid is a tanky and powerful build with good AoE and consistent single target damage. Dolmen Stone, Symbiotic and Metamorphic Stone are mandatory for the build to function. It excels at all content, whether it be Uber Lilith, Speed Farming, or the highest level of Nightmare Dungeons, which is Tier 100. The build features high defenses through multiple Legendary Aspects, as well as a ton of stackable Damage Reductions on gear. Its unique playstyle revolving around Dolmen Stone makes it very enjoyable and as close as you can get to a classic Hammerdin in Diablo II... except for those moments when you encounter a Suppressor Elite.

  • Activate Blood Howl and Hurricane.
  • Spam Boulder and weave in Wind Shear to benefit from many Buffs.
  • Use Petrify against dangerous threats.
  • Fill your Spirit easily thanks to Umbral and your constant CC, in particular from Boulder.
  • Run through hordes of monsters and enjoy your big rocks!
