Important

Incinerate Enchantment may not enable Conflagration anymore. In this case the build will change after launch.

Welcome to the Firewall Sorcerer Endgame Guide! This build is for those who want to set the world on fire.

Firewall received some buffs to allow it to be a more comfortable Endgame build, while it is less powerful than Incinerate it has the benefit of not being a Channeling Skill. Familiar will provide a damage bonus with Invoked Familiar, try to keep one Fire Familiar active. Flame Shield makes you Immune for a few seconds which is invaluable for avoiding dangerous stacks in Pits along with providing Unstoppable, which will break active crowd control. Teleport will allow you to reposition for damage or defense along with providing Unstoppable. Ice Armor will provide a large Barrier and a damage increase thanks to Storm Swell. Inferno gives a large damage bonus and removes the Mana cost from Pyromancy Skills with Supreme Inferno, use this whenever available to group enemies and deal more damage.

Tal Rasha's Iridescent Loop is a large part of your gameplay, requiring you to stack your three different elements to gain a large damage bonus and then rotate two to maintain it. Ice Armor will provide your Frost Skill and Teleport will be your Shock Skill and main rotation with your Pyromancy Skill Firewall.

Note

This build guide assumes you have a Level 60 Character and unlocked Torment 1. To get there, level up with one of our Sorcerer Leveling Guides. See how this Build compares against others with our various Build Tier Lists.

Boss Powers

Season 8 - Belial's Return
Firewall Sorcerer

Season 8 is the Season of Belial's Return. It allows you to tap into Boss Powers obtained from World, Event, and Lair Bosses throughout Sanctuary. The new seasonal mechanic, Apparition Incursions, is available at any difficulty level and gives you the opportunity to unlock a subset of these powers very early on. Various Apparition Monsters appear in these special timed events throughout Sanctuary. Defeating these monsters spawns 1 of 10 Apparition Bosses to hunt you down and defeating them grants you their Boss Power. After defeating the first Boss, continue the event for a chance to fight a second Apparition Boss, after which Belial himself joins the fray.

There are 24 Boss Powers available and the first time you defeat one of these Bosses, you claim their power for yourself. Boss Powers each have Main and Modifier effects to boost your build. 13 are available in all difficulties (from Apparition Incursions and World Bosses), while 11 can only be acquired in Torment 1 difficulty or higher from Lair Bosses and Lilith. You can equip 1 Main Power and 3 Modifiers, and all powers can be upgraded up to Rank 20, increasing the potency of both the Main and Modifier effect. You use Spectral Ash to upgrade these powers, dropped from Apparition Incursions and by defeating any Bosses. Boss Powers also scale with your Paragon Level, growing stronger as you progress.

Best-in-Slot Boss Powers

Main Power

Urivar's Lobbed Bombs - Extra Cooldown Reduction provides additional quality of life but the damage won't scale as well in this build. On the plus side it adds cool explosions.

Modifiers

  • Andariel's Flaming Skull - This provides a strong multiplier but will take time to rank up.
  • Harbinger of Hatred's Volley - This provides a strong multiplier but will take time to rank up.
  • Sinerat's Flames - This provides a good multiplier and is easy to activate without tempers.
Firewall Sorcerer Endgame Boss Powers

Alternate Boss Powers

  • Sinerat's Flames - Main: This provides area burning damage but sacrifices potential Firewall Size utility tempers by replacing it with Flesh Reaper's Disruption. Might be the best option for Speedfarming but it's power was greatly reduced.
  • Flesh Reaper's Disruption - Modifier: This provides a good multiplier but requires Crowd Control Duration utility tempers to activate.
  • Kirma's Sparks - Modifier: This provides Evade Cooldown Reduction for better mobility.

Skill Rotation

  • Cast Ice Armor and Teleport to activate Tal Rasha's Iridescent Loop, follow up with Inferno then Familiar to start activating NaguCeh.

Sorcerer Enchantments

Incinerate is our first Enchantment. This will give us extra damage with Conflagration.

Teleport is a useful Enchantment for adding more mobility to your gameplay. This replaces your evade with a shorter range Teleport than doesn't make you Unstoppable.

Fireball now has an execute to make it more viable. This can be used for Speedfarming or as another Fire Enchantment for Enchantment Master.

Important

Carefully check your Paragon Boards to ensure correct board rotation. Glyphs go from a radius of 3 to 4 at level 15 and from 4 to 5 at level 46. Some of them cannot be activated before reaching these thresholds! Progress through The Pit to rank up your Glyphs.

Use the slider to see the progression steps. At around Paragon 200, leveling slows down significantly and all important Rare clusters, Legendary nodes and Glyph sockets should be unlocked. Afterwards, you can min/max your build with minor tweaks and by picking up additional smaller nodes.

Mercenaries

Season 8 - Belial's Return
Firewall Sorcerer

Mercenaries are unlocked during the Vessel of Hatred campaign and assist you in battle. There are 4 separate Mercenaries to choose from, each with their own skill trees and abilities. You can have one hired (permanent) mercenary during solo play and a reinforcement who assists you from time to time in certain situations.

Hired: Subo

  • Subo is a great choice for casual gameplay thanks to his passive Seeker that reveals enemies and objects, this is a nice quality of life addition and also gives some Mana sustain. Grab Molotov along with Scorched Earth to boost your damage over time. Next you pick Snipe along with Incendiary Bolt to trigger the Scorched Earth as well.
  • Raheir is a great alternative if you don't mind dropping the maphack, Valiance is an amazing defensive tool that will prevent damage from large hits along with give you Unstoppable. Take Ground Slam and grab Raheir's Aegis for extra defense. Next you want Bastion with Inspiration. Valiance is a very powerful mechanic for pushing more difficult content or playing on Hardcore.

Reinforcement: Raheir

  • Raheir will potentially save your character with his reinforcement Bastion. Setting this to trigger on injured can keep you going in difficult encounters.
  • Aldkin can provide additional damage reduction with Field of Languish if you are using Raheir as your Hired, set it to cast on any skill.

Item Progression Goals

Before you dive into the Endgame with the Firewall Sorcerer, take a look at this overview of the items used in the build. See below for further details about the different progression steps and variants. Some of your Skill Tree choices depend on what Legendary Aspects and Unique items are available to you.

Build Variants

Season 8 - Belial's Return
Firewall Sorcerer

This section is designed to guide your Firewall Sorcerer from a fresh level 60 into the very late endgame using the three variants Starter, Ancestral and Mythic. At the final step, you should be fully decked out with a great all-rounder build. From there, follow the other min/max variants if you want to optimize around certain activities such as Pit Pushing, Speedfarming and more.

Starter
Ancestral
Mythic
Speedfarm
Pit Push

If you are fresh in Torment 1 coming from a leveling guide, this is where you begin. Since only some Aspects can be guaranteed from Dungeon unlocks for the Codex of Power, focus on acquiring the additional aspects via gambling with Murmuring Obols.

Gear & Skills

Starter Firewall Sorcerer Gear
Starter Firewall Sorcerer Skills
  • Early on in your progression, focus on Armor & Resistances to survive. Each Torment difficulty adds a penalty of -250 Armor and -25% all Res and it's recommended to keep both capped (1000 Armor, 70+ Res) at all times. As you unlock higher power gear, masterworking levels and more Paragon points, you naturally scale your character into the higher difficulties and can start replacing some of these rolls with offensive or utility stats.
  • Scale Flamefeeder and Torch for Combustion.

The goal here is to progress through the Torment difficulties as you unlock Ancestrals, Paragon points, all Legendary Aspects, Temper mods and the most important Uniques to pilot this build. Some Legendary Aspects are used temporarily to fill slots that may be replaced with more Unique items later on.

Gear & Skills

Ancestral Firewall Sorcerer Gear
Ancestral Firewall Sorcerer Skills
  • As you upgrade your gear to Ancestrals with more masterworking levels and reach higher paragon, you can focus more and more on replacing Armor & Resistance rolls with better stats, but ensure to stay capped at 1000 Armor and 70%+ Resistances for the difficulty you're currently in.
  • Flickerstep quickly reduces your Teleport Enchantment cooldown and helps reset your Inferno.
  • Tal Rasha's Iridescent Loop will require casting your Ice Armor for your Frost stack at the beginning of combat and then rotating Shock and Fire to maintain it.
  • Raiment of the Infinite pulls enemies near your Teleport location, making it easier to group them. Beware of being trapped in the enemies. If you actively move away from the direction enemies are mainly being pulled from then you can avoid the trap.

This is the final version of the build's progression, including all regular Unique items, Mythic Uniques, Legendary Aspects, Temper mods and Masterworking, leaving you with a great all-rounder build for all content in the game. Additional variants use this as a baseline to optimize around certain activities.

Gear & Skills

Mythic Firewall Sorcerer Gear
Mythic Firewall Sorcerer Skills
  • Shroud of False Death provides damage and a good amount of defense thanks to it's bonus to Passive Skills.
  • Harlequin Crest provides massive Cooldown Reduction and Damage Reduction.
  • Ring of Starless Skies provides great stats, a damage multiplier, and reduced Mana costs.

This Speedfarming variant optimizes the build for easy activities like Helltides, Whispers, Nightmare Dungeons and lower Pit Tiers after you have finished the Mythic variant and reached a plateau in your progression.

Gear & Skills

Speedfarm Firewall Sorcerer Gear

  • Raiment of the Infinite can help group enemies quickly at the cost of Defense.
