Equip A Catalyst to a Hotbar Slot Apply an Infusion to Change the Damage Type Choose Up to Three Arcana to Further Customize Use Horadric Jewels to Empower Your Horadric Spell |

Catalysts are the core of your customized Horadric Spellcraft. To use one, equip a Catalyst to a Hotbar slot that corresponds to one of your active skills. When you use that skill, the Catalyst will activate as long as it’s off cooldown.

The primary way to customize your Horadric Spell is by applying an Infusion, which changes its damage type and adds unique effects. There are five Infusions, each corresponding to a different non-physical damage type.

You can enhance your Horadric Spell further by selecting up to three Arcana. Each Arcana adds a unique offensive, defensive, or supportive effect.

As another part of the Season 9 update, you can also socket Horadric Jewels on your Rings or Amulet to further empower your Horadric Spell with more unique effects.

You can upgrade your Horadric Spells by using Horadric Phials. Simply select them on the Horadric Spellcraft Menu and pressing the Upgrade Power button.
| Spellcraft Type | Ranks | Cost |
|---|---|---|
| Catalyst | Ranks 2-4 | 25 Phials |
| Ranks 5-10 | 50 Phials | |
| Infusion | Ranks 2-4 | 25 Phials |
| Ranks 5-10 | 50 Phials | |
| Ranks 11-14 | 100 Phials | |
| Ranks 15-20 | 200 Phials | |
| Arcana | Rank 2 | 25 Phials |
| Rank 3 | 50 Phials | |
| Rank 4 | 100 Phials | |
| Rank 5 | 200 Phials |

The Horadric Spell is a customizable skill that you can put together. You start by choosing a Catalyst, which determines the base effect of the spell and can be bound to any skill on your hotbar. You can then enhance the spell by adding an Arcana for additional effects and Infusions to change the damage type, making it better suited to your build.
