Build Introduction
The 
Firewall Sorcerer deals Burning Damage to melt enemies. This build utilizes a “fire and forget” playstyle, casting Firewall to build fatal damage over time before moving on. 
Familiar seeks out enemies to supplement the Firewall Sorcerer with additional Burning Damage from Enhanced Familiar.
Season 7 Update (Patch 2.1.0): The patch update allows damage from Enhanced Familiar to scale up with Skill Ranks of Familiar. The Burning damage from Fire Familiar greatly supplements damage output for early leveling!
Check the Sorcerer Leveling Guide Overview for a comparison of all the starter builds on Icy Veins.
Once your Sorcerer character reaches Level 60, switch to the Endgame Guide for the Firewall Sorcerer to continue this build.

Build Mechanics and Playstyle
This Fire build is focused on Damage Over Time from Firewall and Familiar. Its damage is enhanced with 
Combustion, by applying other Burning sources from 
Fire Bolt and 
Inferno.
When lethal Burning damage is stacked on enemies, move on to the next group of enemies. Freeze tougher opponents and stack multiple Firewalls/Familars to build up the Damage Over Time.
Damage Rotation
Optimize DPS with the following rotation.
- Cast Firewall under enemies.
- Cast Familiar to auto-seek enemies for additional damage output.
- Cast
Frost Nova to Freeze enemies while they are standing in multiple Firewall placements. - If needed, use Inferno to group enemies up and freely spam Firewall.
- Spam Fire Bolt to regenerate Mana.
Gear, Gems, Elixirs, and Stats
The following sections cover the important systems that are essential to improving the power of your character during the leveling process.
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.

If you are playing the Season of Witchcraft (Season 7), visit Gelena at the Tree of Whispers to craft Occult Gems. The recommended Occult Gems are included in the Firewall Sorcerer endgame build guide due to their high crafting costs.
Runes are unlocked during the Vessel of Hatred campaign and then start dropping during various activities. A Rune of Offering and a Rune of Invocation can be combined by inserting them into equipment with two available sockets, creating a Runeword. A limit of two Runewords can be equipped.

Elixirs and Health Potions
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.
Elixir of Resource 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. 
Elixir of Advantage increases damage output, if not already capped at 100% Attack Speed bonus from gear and Paragon.
Elixir of Fortitude is the best general-purpose option for survivability.
Return to the Alchemist every 10 Levels to upgrade your potion. The extra healing is essential to survival.
Stat Priority and Tempering Affixes
Listed below are the affixes to prioritize on gear for Firewall Sorcerers during the early leveling process. Each line of affixes are listed in order of importance. Affixes on the same line are considered to be equally important, but their benefits may vary depending on how much is stacked compared to other character stats.
When comparing weapons with similar item levels, Two-Handed Staves are preferred over One-Handed Weapons for higher damage per hit while leveling.
Tempering Manuals are randomly dropped while leveling, and they need to be found to unlock their usage at the Blacksmith. Each manual has Magic, Rare, and Legendary rarities that determine the range of values available. Rare Items can inherit 1 tempering affix, while Legendary Items can inherit 2 tempering affixes from different categories.
The most beneficial tempering affixes while leveling are included below. If tempering materials (
Iron Chunk and 
Veiled Crystal) are limited, prioritize the Resource, Weapon, and Offensive categories. The best-in-slot tempering affixes are available in the Endgame Guide for the Firewall Sorcerer.
