The Skill Tree above shows the full allocation of 71 Skill Points for the Firewall Sorceress build. Make sure you obtain the 12 Skill Points available from Renown.

Enchantment Slots

Non-Ultimate Skills can be equipped in two available Enchantment Slots. A skill must have at least one skill point allocated to it in order to be used in the Enchantment Slot. Skill points that have been granted through gear work as well.

Slot FirewallFirewall in the first Enchantment Slot, as it will have a chance to trigger two additional Firewalls underneath enemies when they take burning damage. 

Slot FireballFireball in the second Enchantment Slot for explosions to help against groups of enemies.

Alternative options include MeteorMeteor for the Meteor hybrid build variant and TeleportTeleport for the Telestomp build variant.

Paragon Board

After Character Level 60, experience gains are applied to Paragon up to Level 300. A maximum of 228 Paragon Points can be obtained through Paragon Levels, Renown, and Altars of Lilith. Follow the Paragon setup designed for the Firewall Sorcerer to gain a considerable amount of progression for your character.

Glyphs are inserted into sockets on each Paragon board and can be found during various activities in Diablo 4. Level up the Glyphs included in the Paragon setup by completing The Pit. Clearing higher tiers of The Pit allows Glyphs to reach higher levels.

Important Notes:

  • Make sure you select the correct Legendary Boards and rotate them into the proper orientation.
  • Attach Legendary Boards in the order shown, as bonus requirements of Rare Nodes increase with their placement order.
  • Prioritize leveling each of your equipped Glyphs to 15 to gain the increased radius, which can be required to meet additional bonus requirements.

1. Starting Board (Exploit)

2. Fundamental Release (Unleash)

3. Frigid Fate (Pyromaniac)

4. Burning Instinct (Control)

5. Enchantment Master (Elementalist)

Elixirs

  1. Elixir of AdvantageElixir of Advantage increases damage output, if not already capped at 100% Attack Speed bonus from gear and Paragon.

Stat Priority and Tempering Affixes

Listed below are the affixes to prioritize on gear for Firewall Sorcerers. Each line of affixes is 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 or other character stats. Bolded affixes are the most important targets for Masterworking upgrades.

When comparing weapons of similar item levels, One-Handed Weapons are preferred over Two-Handed Weapons, as a Focus provides more beneficial utility affixes. A Wand or a Dagger is selected for the useful implicit stats.

Critical Strike Damage is beneficial due to it increasing the bonus multiplier on Burning InstinctBurning Instinct.

The priority order of Resistances is Lightning > Poison > Fire > Cold > Shadow. Maximum Resistance is 70% by default for each element and can be increased to 85% by various sources.

Armor is only needed until capped at 1,000.

If you are using a speed setup with Teleport Enchantment, temper the Evade Cooldown Reduction affix from the Natural Motion Manual onto your Boots and Amulet. Otherwise, temper the Movement Speed or Teleport Cooldown Reduction affixes.

Check the Tempering and Masterworking section for more details on Blacksmith upgrading.

Advanced Information

Additional details are provided in the following sections for a more in-depth explanation of the Firewall Sorcerer. Read this advanced information after understanding the basic overview of the build in the previous sections.

Build Mechanics

This Fire build is focused around powerful Damage Over Time (DoT) from FirewallFirewall. Its damage is enhanced with CombustionCombustion by applying other Burning sources from Flame ShieldFlame Shield and InfernoInferno.

Critical Strike Damage is applied to Burning Damage with Burning InstinctBurning Instinct from Paragon. This allows us to benefit from Critical Strike Damage on gear.

Firewall Meteor Sorcerer Build Variant

Supplement FirewallFirewall by dumping highly damaging MeteorMeteor showers with Starfall CoronetStarfall Coronet. This Unique Helm powers drops additional Meteors and applies a Cooldown to the Skill. Starfall Coronet is required for this build variant, so farm the Beast in Ice Uber Boss until it drops!

The Firewall Meteor Sorcerer makes the following changes to the original build in this guide.

Telestomp with Raiment of the Infinite

Raiment of the InfiniteRaiment of the Infinite allows the Firewall Sorcerer to use 2 sources of TeleportTeleport offensively. Teleporting on top of enemies to Stun and group them up is called “Telestomping”. This playstyle can quickly clear groups of enemies and keep them Crowd Controlled (CC) for safety, perfect for speed-farming Helltides, Nightmare Dungeons, and The Pit!

Use the following setup for the Telestomp Sorcerer.

Obol Gambling

Obol gambling is a great way to potentially find item upgrades or items missing from your build. Use Obols on your target equipment for a chance to receive Greater Affixes. Check out the new tool from Icy Veins for gambling Obols in the link below.
