Season 4 - LootC-Tier

Share on Social

Welcome to the Firewall Sorcerer Endgame Build Guide. This build lets you set the world aflame and watch everything burn. It has very good AoE coverage but struggles against Bosses. It's definitely not the fastest build to clear Nightmare Dungeons, but since there's no clock to race against, you can just take your time and slow bake some demons. As long as you can stay alive, they will burn. Eventually.

This build is essentially melee because if you don't stay next to the monsters they will immediately run out of your Firewalls. Your usual gameplay loop consists of building a giant pyre and then running in circles around it, while chanting ritual spells and/or laughing maniacally.

The Firewall Sorcerer is a very reliable and robust build that doesn't require anything to work. You don't really need any non-Codex Aspects nor any specific stats on your gear to burn everything. This makes Firewall Sorcerer the best for leveling and early endgame, but it also means that it doesn't scale as well as other builds.

In this guide we teach you all you need to know to satisfy your hidden arsonist fantasies. Let's dive into it!

Firewall Sorcerer Endgame Setup

The PitWeak

Season 4 - Loot Reborn

In Season 4, the Season Theme revolves around helping out the Iron Wolves. Compared to past themes, this one does not offer any borrowed power as the entire game has been redesigned with new itemization and crafting options, increasing player power substantially across the board. Instead, you can gather reputation similar to the Vampire Bounty Board from Season 2 to unlock rewards that supercharge your leveling journey to 100 with extra items, crafting materials and eventually even a Resplendent Spark to craft an uber unique.

We recommend to follow the seasonal questline until you unlock the reputation system, check which rewards suit you most and then follow your regular leveling path. To learn more, check out our full Season 4 guide for more information.

Skill Tree & Gameplay

  • Firewall is our main damage skill. We spam it all the time with or without a reason.
  • Teleport is our main mobility skill, which also serves as a CC break. In the late game it also groups enemies together via Raiment of the Infinite.
  • Frost Nova is used to apply Vulnerable and Freeze to enemies, greatly increasing our damage. Use it right after you group up enemies.
  • Ice Armor gives us a huge Barrier and a bit of Mana regen.
  • Flame Shield provides even more defense, as well as some healing.
  • Ice Blades is our last active skill. It gives us an extra stack for Tal Rasha's Iridescent Loop and reduces our cooldowns.
Firewall Sorcerer Skill Tree

Generally, Firewall Sorcerer follows a very simple rotation:

  1. Group up enemies.
  2. Apply all debuffs to them.
  3. Spam Firewalls until debuffs run out.
  4. Keep enemies inside these buffed Firewalls until they burn to death.

Enchantment Slots

Sorcerers can choose two skills to put into Enchantment Slots, where they provide powerful passive bonuses. Firewall Sorcerer uses the following Enchantments:

  • Firewall Enchantment gives us up to 200% more Firewalls per Firewall, which is obviously amazing.
  • Ice Blades Enchantment gives us more Cooldown Reduction and more damage via Conjuration Mastery.

For speedfarming, we use Fireball and Teleport. The former lets us kill groups of weak enemies faster and the latter lets us zoom across the map.

Learn more details and how to unlock this class specification in our full Sorcerer Enchantment Slots Guide.

Resource & Cooldown Management

This build doesn't use a lot of Mana due to Firewall's low cost and attack speed.

Prodigy’s Resource Aspect

This is our main source of Mana in the early game. Apart from Firewall all of our skills have a Cooldown and give us some Mana when activated.

  • Always start by casting a Firewall or two before using your other skills, so that the Mana is not wasted
  • Don't use your Cooldowns all at once for the same reason

Supreme Inferno

This upgrade to our Ultimate Skill simply makes our Firewall free for 8 seconds. We use Inferno in the early game but later on both its functions are covered by Raiment of the Infinite and Mana Per Second respectively.

Stats on Gear

In the late game with good gear we can get rid of Prodigy’s to play one more Offensive Aspect. To do this we need to stack enough Mana Per Second (rolls on Boots, Helmets, and Chests). Combined with Shimmering Ice Armor and Conjuration Mastery this stat can give us more Mana than we can spend even if we stack Attack Speed.

Paragon Board

Carefully check your Paragon Boards to ensure correct board rotation. Glyphs go from a radius of 3 to 4 when they reach level 15!

← Scroll to Level →

Level the Paragon Board by scrolling. Each step optimizes progression.


We need to level up our Glyphs to activate their Additional Bonus with surrounding nodes. For some Glyphs, we max our bonuses by allocating every relevant node in range, while on others we take the minimum required for the Additional Bonus only. Because Glyphs at level 15 increase their radius, we need to prioritize leveling them by completing Nightmare Dungeons. After that, we prioritize leveling our strongest glyphs to level 21.

Note that there are some Glyph position swaps and a few adjustments to surrounding Paragon nodes once they reach level 15. See the first three steps in the Paragon progression above for details. The setup displayed by default is the final version of the build.

Glyph Leveling Priorities

For maximum efficiency, follow the order outlined below. First, level your Glyphs to level 15 and then do a second pass to get them all to 21.

Level 15

  1. Destruction
  2. Tactician
  3. Control
  4. Pyromaniac
  5. Exploit
  6. Elementalist
  7. Reinforced

Level 21

  1. Destruction
  2. Control
  3. Exploit
  4. Elementalist
  5. Reinforced
  6. Tactician
  7. Pyromaniac

Endgame Gear & Skill Progression

When you start diving into the Endgame, you don't have all the tools available to achieve the final build versions. Let us guide you through different progression points to give you a smooth transition from our Leveling Guides to the final build version.

Progression Goals

Many of your Skill choices depend on what Legendary Aspects and Unique items are available to you. While we can guarantee, that everyone has access to the same Codex of Power Aspects, the progression might be different for everyone!

  1. Unlock the following Aspects in your Codex of Power:
  2. Find the following Legendary Aspects either as a random drop or by gambling with Obols:
    • Conceited: Gamble Focuses
    • Shredding Blades: Gamble Focuses
    • Searing Wards: Gamble Pants
    • Everliving: Gamble Pants
      • Replaces Snowveiled
    • Fortune: Gamble Boots
      • Replaces Disobedience
    • Concentration: Gamble Pants
      • Replaces Searing Wards when we start using Ice Blades.
  3. Acquire the following Unique items either as a random drop or by farming specific Boss drops.
    Note: You cannot gamble Unique items with Obols!
    • Raiment of the Infinite (Varshan, Zir)
      • Replaces Fortune
    • X'Fal's Corroded Signet (Duriel, Andariel)
      • Replaces Edgemaster’s
    • Tal Rasha's Iridescent Loop (Varshan)
      • Replaces Shredding Blades
  4. If you're lucky enough to obtain the following Uber Uniques, they're useful for the build.
    • Harlequin Crest: replace Everliving. This item provides a similar damage increase and much more survivability and utility.

Learn more details and how to farm Legendary Aspects and Uniques in our General Farming Guide.

Progression Steps

Leveling to 100
Endgame & The Pit

Once you have completed the leveling guide, only the Codex of Power Aspects are guaranteed. With this setup you can farm the Legendary Aspects and Unique items you need for the next progression point.


  • Storm Swell goes on the amulet for extra damage.
  • Prodigy’s is a Resource Aspect so it must go on a Ring.
  • Put Edgemaster’s and Control on your and Gloves or Weapons or 2nd Ring.
  • Bounding Conduit can only be imprinted on Boots.
  • Put Disobedience and Snowveiled on Chest and Pants
Codex-only Gear

Skills & Enchantment Slots

In the early game we use INF to help with mana and FBE to kill small enemies faster.

  • Remove Ice Blades.
  • Remove Conjuration Mastery.
  • Add Supreme Inferno.
  • Add Greater Fireball.
  • Move 2 points from Endless Pyre to Fiery Surge.
Starter Skill Tree

With more level, better stats on items, and better rolled aspects our build can progress further. In this version we do a bunch of changes to our gear, skills and enchantment slots. See below to find out when and why each change is made.


  • We add all our non-Codex aspects. It's best to put Shredding Blades on a Ring because it will be replaced by a Unique later.
Early Endgame Gear

In this setup, you have access to all Unique items, and Legendary Aspects. This allows you to pilot this build at its peak efficiency. Let's take a look at the changes you need to make and when to implement them.


The final version of our build uses 3 Uniques:

  • Raiment of the Infinite
  • X'Fal's Corroded Signet
  • Tal Rasha's Iridescent Loop

Each of them can be used as soon as you find it and it will give you a nice boost. Just make sure to keep Prodigy’s until you have enough Mana Per Second.

We also replace Bounding Conduit with Concussive Strikes for maximum damage.

Late Endgame Gear

Gear with Uber Uniques

Our optimal gear includes only one Uber Unique - Harlequin Crest.

BiS Gear


When we get Raiment of the Infinite and Tal Rasha's Iridescent Loop we can remove Inferno and switch to our final skill tree with Ice Blades and Conjuration Mastery.


Raiment of the Infinite changes the way you use Teleport. You need to be more careful and try to never Teleport into the unknown. First, walk up (or Evade up) to the enemies until you can see all of them, and only then Teleport in the right spot to pull everything together.

Endgame Skill Tree

The Speedfarming setup makes you more efficient in farming the Open World, Helltide zones, Tree of Whispers, regular Dungeons, and low tier Nightmare Dungeons.


  • Replace Raiment of the Infinite with Fortune Chest with +Ranks to Teleport.
  • Put Bounding Conduit on the Boots.
  • Get an Amulet with Evade CDR temper.

Enchantment Slots

Replace Firewall with Teleport and Ice Blades with Fireball. The former lets us move faster while the latter helps us kill faster

Speedfarming Setup


  • Remove Ice Blades and Conjuration Mastery.
  • Remove Endless Pyre.
  • Max out Teleport.
  • Put 2 points into Precision Magic.
  • Add Greater Fireball.
  • Use any other Cold skill in place of Ice Blades.
Speedfarming Skills

Hardcore Adjustments

Hardcore requires you to build into more defenses. Here are some tips to successfully navigate this build through potentially dangerous situations:

  • Prioritize Maximum Life over Intelligence on your Gear.
  • Replace Affix with Searing Wards Pants.
  • Replace Tactician with Territorial.
  • Take Skill Points out of Glass Cannon and put them into Align the Elements and Elemental Attunement.
  • Only farm Nightmare Dungeons with monsters that are about your character level when you have near optimal gear.

Build Scaling & Stat Priorities

Learn about the important build scaling mechanics and stat weights.

  • Cooldown Reduction (CDR). This is the most important stat for any Sorcerer build. What good are our skills if we can't use them because they are on cooldown? In purely offensive terms, CDR gives us the following:
    • More uptime on Vulnerable and Freeze from Frost Nova (about a 3x damage buff)
    • More uptime on Barrier from Ice Armor or Protection, activating Conceited and Storm Swell (1.625x damage buff)
  • Mana. We continue to chase our philosophy of being able to use skills = good. The next skill we want to use is Firewall, which has a Mana cost instead of a Cooldown. We need to stack enough Mana Per Second so spam Firewall all over the place.
  • Offensive Stats. We want most of the normal offensive stats: Firewall Ranks, Weapon Damage, Attack Speed, Intelligence, and all kinds of Additive Damage, in that order of priority.
  • Critical Strike Damage. This stat becomes useful after we get the Burning Instinct Node, ranking somewhere between Attack Speed and Intelligence.
  • Lucky Hit Chance. Becomes a nice offensive stat with X'Fal's Corroded Signet.
  • Critical Strike Chance doesn't directly buff our damage because Firewall can't crit.
  • Cooldown Reduction (CDR). As with our damaging skills, our powerful Defensive Skills are not doing much if we cannot cast them. Flame Shield makes you immortal and Ice Armor is Flame Shield with 3x the duration at best or a protective layer that almost doubles your HP at worst.
  • Barrier. Mostly coming from Ice Armor, it is our main defense outside Nightmare Dungeons. With our high and consistent damage output, the Barrier will instantly refresh as long as it's not broken in one hit.
  • Armor is the major source of Damage Reduction against Physical damage. We naturally get Armor just from having high Item Power gear, and we further boost it with Skulls in Jewelry and. It's extremely important to reach the Armor cap of 9,230 as the last few points of Armor get exponentially more effective.
  • Resistances give us damage reduction against Elemental damage. Similar to armor it should be stacked as close to the 70% cap as possible for full effectiveness. As a Sorcerer, we get lots of Resistances from our high Intelligence and our Paragon Boards, letting us almost reach the cap without sacrificing any stats on gear.

Stat Priorities

To enable your build to perform optimally, you need to reach certain Stat "Breakpoints". Some examples are reaching 100% to Critically Strike, or 20 Resource per second. Since there are many values of these stats on different pieces of gear, read the checklist below and refer to the recommended Tempered Affixes and Masterwork Crits . Desirable Greater Affixes will always be the top three recommended Affixes.

FAQ & Mechanics

Once a guide is released, many players have questions on why and how we are approaching certain choices. In this section you can find the answers to the questions that have been asked the most.

Why don't you use Imbiber?

Why no Incendiary Aspect?

Why no Aspect of Engulfing Flames?


Learn all you need to know about how to scale this build in the endgame.



The Firewall Sorcerer is a fun and flavorful build, capable of dealing great AoE damage while covering your entire screen in flames. It's very strong early but doesn't scale as well into the late game. Still, it can definitely clear all the endgame content, be it World Bosses or Nightmare Dungeons, it will just take some time.

  • Spam Firewalls to bring down enemies' HP and set off a chain reaction of Fireball explosions.
  • Don't look at the explosions.
  • Stack Cooldown Reduction, Mana Cost Reduction, and Resource Generation to spam Firewall without a care in the world.
  • Use Ice Armor, and Flame Shield to stay alive.
  • Build a big fire under your enemies and then dance around it (literally).
