Wrecking Ball Boulder

The Boulder Druid Build Guide teaches you about Gear, Skills, Paragon, Playstyle & Seasonal Mechanics in Diablo 4 Season 11.

Boulder is an easy-to-play, mobile and one of the strongest builds in the entire game. Offers large AOE and great mobility by integrating Shred in the build.

The playstyle for this build is very smooth, as you are able to cast your main skill Boulder while moving, allowing for a very satisfying gameplay feeling. You will be moving forward and clearing any enemies around you in a medium area, you can think of it as a melee build with a large circular clear. It's also fairly mobile with high base mov speed, the ability to use Teleport via runes, and to teleport to enemies with the skill Shred.

• Cast and maintain Cataclysm.
• Mjölnic Ryng makes us get infinite Spirit and more damage.
• Cast and maintain Hurricane.
• Dolmen Stone will ensure our Boulder orbit our Hurricane.
• Spam Boulder.
• Until you have 10 up.
• Cast Earthen Bulwark for Unstoppable.
• Cast Shred for Mobility.

Boulder Druid functions by using Dolmen Stone, to allow our Boulders to oribt around our Hurricane, and Aspect of Metamorphic Stone making it a Core Skill.

By using a combination of Hurricane Duration, Nature Magic Cooldown Reduction and Ranks to Endless Tempest, we get to keep Hurricane up indefinitely.

Likewise, with Cataclysm, we use Ranks to Endless Tempest, Nature Magic Cooldown Reduction and Calamity to keep it up indefinitely. In combination with Mjölnic Ryng, we get damage and more importantly, infinite Spirit.

Leveling

It is not really possible to level with Boulder Druid as it requires specific Uniques to function. I recommend you level with this Shred Build instead.

Mercernaries

We use Subo with Wire Trap for Movement Speed and Cover Fire for Critical Strike Damage. In addition, Subo provides us with the invaluable ability to see Elites on our Minimap.

Our secondary Mercenary is Raheir with Crater to pull in.

Runes

Initially, we use Moni + Que to get better uptime on Earthen Bulwark while we Shred around for mobility. We also use Cir + Zec to help keep Cataclysm up.

Later on, we swap to Igni + Que and Cir + Ohm for more damage.

For Speedfarming, we can use Bac + Jah instead of Cir + Ohm.

Spirit Boons

Deer

• Wariness to be tankier. Prickleskin is an option for more damage.

Eagle

• Swooping Attacks for Attack Speed. Iron Feather is also an option to be tankier.
• Avian Wrath for Critical Strike Damage.

Wolf

• Calamity to help with Cataclysm uptime.

Snake

• Early on, we will use Calm Before the Storm to help with Cataclysm uptime.
• Later on, we will use Obsidian Slam to Overpower more often.

Elixirs and Incenses

It's important to run Elixirs and Incenses at all times. Not only because they increase your Experience gain, but also because they provide very strong combat boosts.

For Elixirs, you will use Elixir of Advantage for Attack Speed, or Elixir of Fortitude for more Maximum Life.

For Incenses, you will use Spiral Morning for All Stats, Reddamine Buzz for Maximum Life and Soothing Spices for All Resistances and more Armor.

Masterworking and Greater Affixes Explained

Masterworking

• Since Season 11 Masterworking no longer increases your item’s affix values. Instead, it improves the Quality of an item, which gives a bonus to the base damage, armor, or resistance of an item.
• Items can be Masterworked to a maximum Quality threshold of 20. Each time you Masterwork the item, it adds a random amount of Quality to the item (from 2-5 levels). Once at maximum Quality, you can roll it one last time for a Capstone bonus.
• This Capstone bonus upgrades a random non-greater affix on your item into a Greater Affix. You can then choose to re-roll the Masterworked Greater Affix, without resetting your Masterworking Quality. Re-rolling the current Masterworked Affix will cost Obducite and Neathiron.

Greater Affixes

Greater Affixes (GA) on an item force the affix to roll at the top of it's range of possible values and then applies a 50% increase to its value. GA increases are additive with Masterworking increases.

In this planner, the yellow star to the left of an affix denotes that is a GA.

Masterworking and Greater Affix Priority

Unless a certain amount of a stat is required and no more, like in the case of Attack Speed Breakpoints, Armor and Resistances, the Capstone Bonus is not necessary.

Guides, which follow a Starter -> Midgame -> Endgame progression, are structured such that the difficulty of the MWing outcome and amount of GAs on items also progresses as expected.

For example, a Starter variant will generally have 1GA items. A Midgame variant will generally have 2GA items. An Endgame variant will generally have 2GA/3GA items with a perfect Capstone Bonus.

From this you can derive that the GA on the starter version is the most important, the second GA added is the second most important and the third GA added is the third most important affix.

When GA and Capstone don't align you are most likely in the presence of a stat with a certain threshold you have to meet or a cap and those will be explicitly stated in the guide anyways.

In the case of Uniques GA and Capstone, progression standards are generally shifted by one as they are easier to MW because they have 4 affixes and also easier to acquire with multiple GAs.

Frequently Asked Questions

When should I switch into this build?

The best thing you can do is wait till you drop a Dolmen Stone with GA cooldown reduction, that makes all the requires of the build go down drastically.

Vasily's Prayer doesn't need to have any specific GA and Mjölnic Ryng follows the same logic.

Minimum Viable?

Your Cataclysm and Hurricane duration need to be greater than their cooldown and everything will be fine, it's also possible to recover some of the cdr of Cataclysm with the Boon Calm Before the Storm so you can be a little more lax on this.
