Gear, Stats, Gems, and Runes

The following sections cover the important systems that are essential to improving the power of your character during the leveling process. Higher Item Power generally indicates stronger gear, but you should also consider the affixes and effects that are relevant to your class and build.

Legendary Aspects

Higher Tier Aspects with more potent effects can be found on dropped Legendary Items. Salvage unwanted Legendary Items at the Blacksmith to unlock these Aspects in the Codex of Power, and then imprint them onto well-rolled Rare or Legendary Items. Check the in-depth Aspect and Codex of Power guide for more information.

Note: Serpentine Aspect is not recommended while leveling, since you do not have enough Mana regen to sustain its cost.

Listed below are the Aspects found on Legendary Items that are beneficial for the build while leveling, in order of importance. Check the Endgame Build Guide for the Hydra Sorcerer for the best-in-slot Aspect setup.

Build Mechanics

The Firewall Hydra Sorcerer is a hybrid build utilizing multiple Skills to apply Burning damage. Firewall, Hydra, and Familiar can kill enemies while you run ahead.

Primordial Binding gains stacks through casts of Hydra and Familiar, and Ceh if you happen to have it.

Rotation and Playstyle

Optimize DPS with the following rotation.

1. Cast Familiar every 8 seconds. Ensure that the previous Skill cast was a Pyromancy Skill to summon a Fire Familiar. All three charges of Familiar can be cast against bosses and tough elites.
2. Cast Hydra up to two times to spit fire at enemies.
3. Cast Familiar to auto-seek enemies for additional damage output.
4. Cast Frost Nova near enemies to apply Vulnerable from Mystical Frost Nova.
5. Cast Inferno to Pull groups of enemies together.
6. Cast Firewall underneath enemies.

Elixirs

Visit the Alchemist in any main town to craft helpful Elixirs that increase stats and experience gain for 30 minutes. Make sure to forage plants for Bundled Herbs during your adventures; they randomly spawn around the world. Elixirs can also drop randomly from enemies and chests during many activities in Diablo 4.

Listed below are the best Elixirs to consume while leveling the Firewall Sorcerer, ranked by importance.

1. Elixir of Resourcefulness II helps with Mana issues, if you do not already have the appropriate Mana gear. This elixir is highly recommended for starting characters to maintain constant casts of Firewall.
2. Elixir of Advantage II provides the highest damage increase for Hydra.

Return to the Alchemist every 10 Levels to upgrade your potion. The extra healing is essential to survival.
