Season 9 Horadric Spells List and Guide

Diablo 4’s Sins of the Horadrim brings powerful new Horadric Powers—a highly customizable spell system that allows players to tailor their magic to suit their needs and playstyle.

Not only do you get to decide how your spell is constructed, but it also works in tandem with Horadric Jewels, which add another layer of power when socketed into your rings and amulet.

This guide was written by Cliptis.

Your Horadric Spell is Comprised of Three Core Components:

• Catalyst: This determines the type of spell you cast—such as a beam, falling stars around you, or summoned entities that follow you. Each Catalyst type has a unique damage style.
  
• Infusions: These enhance your Catalyst with elemental damage, determining the type of elemental effect your Catalyst applies.
  
• Arcana: These add special abilities, buffs, or debuffs to monsters when you activate your Catalyst. Arcana come in three rarities: Magic, Rare, and Legendary.

Start in the new Seasonal menu located next to your equipment tab icon. First, you'll choose one of five Catalysts:

Catalysts

Next, select your Infusion, which determines your elemental damage. There are five to choose from:

Infusions

As you level up your Infusions, they’ll gain additional abilities. At rank 5, each Infusion enables your Catalyst to break enemy buffs in different ways, depending on your selection. To level up your Infusions, you’ll need to collect Seasonal Currency as you progress through the Seasonal Questline and Seasonal Objectives. 

Now that you have your Catalyst and Infusion, it's time to socket your Arcana. As mentioned, Arcana come in three rarities: Magic, Rare, and Legendary. There are 20 Arcana total. The Magic and Rare types provide basic buffs—like Unstoppable, applying Vulnerable, or increasing Maximum Resource Generation.

Legendary Arcana, however, bring a fun and unique twist. Their effects will change based on the Catalyst you've chosen, introducing a dynamic layer of creativity and flexibility to your build. This system not only offers deep spell customization but also lets you adapt quickly based on the content you're engaging with.

Now that you have completed your Horadric Spell, you now get to pick the slot to put your spell in. The spell slot will correspond to your skill bar, mimicking the placement of your bar.

This means whatever skill you have in that skill bar slot, is what is going to activate your Horadric Spell.

Horadric Jewels are the final piece of your power. You’ll begin crafting these in Torment I, once you start collecting Horadric Tomes—a drop from the new Nightmare Dungeon variant known as Strongrooms.

These tomes function like Tempering Manuals. Once used, they unlock the ability to craft Jewels at the Lapidary in Cerrigar.

To create Jewels, you’ll need:

• Horadric Phials (found in Nightmare Dungeons, Escalating Nightmare Dungeons, Strongrooms, and Lair Boss Chests)
• Jewel Fragments

The following Horadric Jewels are available:

Willbreaker

Physical damage you deal shatters enemies' spirits, causing them to take 40%[x] more Physical damage for 6 seconds. This effect applies when first damaging a Boss or Elite, or when they are affected by Crowd Control.

Seal of Control

While you have two or more Arcana from the School of Control equipped, gain 45%[+] Control Duration and 30%[+] Lucky Hit Chance.

Seal of Power

While you have two or more Arcana from the School of Power equipped, gain 25%[+] Movement Speed and 15%[+] Critical Strike Chance.

Horadric Crest

For each Arcana from a unique School you have equipped, gain 5%[+] Damage Reduction and 1%[+] Maximum Resistance to All Elements.

Note: This Horadric Jewel no longer drops when playing in Hardcore.

“Developer’s Note: It’s important to us as Developers to maintain the integrity and spirit of Hardcore. We welcome any feedback regarding what that means to the community!”

Idol From Below

You gain 6%[x] primary stat, 6%[x] maximum life and you are always Unhindered. However, you will be hunted in Sanctuary's darkest places by Jewel Guardians who were entombed to protect this relic. Jewel Guardians generated by Idol from Below can no longer appear in Training Grounds or after a Dungeon’s objective has been completed. They now also spawn at specific intervals as opposed to two random times.

The Starflux

Your Catalysts deal 100%[x] more damage. However, you lose control over Horadric Spellcraft, causing your Catalysts to inherit Infusions randomly.

As a final update, Blizzard has added a chance for Jewels to drop from Astaroth, the boss at the end of your Escalating Nightmare Dungeon—providing yet another path to obtain these powerful items.

To access all these systems, make sure you complete your Seasonal Campaign. Progressing through it will unlock your new Seasonal abilities, vendors, and crafting options.

I'm genuinely excited about the depth and creativity packed into this system. Get out there, Wanderers—conquer the Strongrooms, fight back the tides of Hell, and let your Horadric powers shine!
