Diablo 4 - Sorcerer Build - Firewall

July 5, 2023

The Sorcerer in Diablo 4 has many viable builds and today we're going to look at the Firewall Build and this guide will show you all the skills you need, aspects to run on your gear and important stats.

This build doesn't need too many specific pieces of gear for it to work and can be used very early on in Diablo 4. To really scale the damage you're going to need some end-game equipment that might be a bit tricky to get.

Compared to other Sorcerer Builds, like the Ice Shards Build, the Firewall build is a lot slower in terms of killing enemies due to it's damage over time but still allows for fun gameplay.

Diablo 4 - Firewall Sorcerer Build Explained

The Firewall Sorcerer in Diablo 4 utilizes one main skill; Firewall! This skill can be spammed across the ground to create huge areas of fire that deal damage over time to enemies. When you through in chance to create meteorites, Barrier multiplicative damage and unstoppable Flame Shield skills, this class is great for wiping out dungeons.

The class can suffer against major bosses because the damage over time is most effective against massive amounts of mobs.

Let's take a look at the main skills:


Firewall -  Your main spamming skill. You'll rarely run out of mana with this skill and it doesn't take much concentration to use. When this skill is enhanced, it also has a chance to create more firewalls, leading to huge amounts of damage over time damage. All you have to do is run around avoiding taking damage whilst your Firewall does the job!

Frost Nova - One of the best skills for Sorcerers that allow you to freeze multiple enemies at once, making them vulnerable. When you stack lots of vulnerable damage bonuses with this build, your damage will start to get spicy!

Teleport - Another key skill for any Sorcerer; this skill allows you to get around maps faster and get out of trouble when you're in a bind. If you pair this with the Unique Raiment Of The Infinite, you can also have Teleport group up mobs making it easier for you to wipe out enemies.

Flame Shield - This skill is another one that can get you out of trouble. Popping Flame Shield will make you Immune and decrease your mana spend or heal 50% of your life.

Ice Armor - Having a Barrier up will help you deal more damage due to the stats we look for on our gear. Ice Armor can last a long time with gear modifiers so it's the perfect skill to pop when trying to increase damage.

Inferno - Your ultimate is a giant fire serpent that wraps around enemies and deals significant damage. It does have a long cooldown, but it's great for using on Elites and big packs of mobs.
