Build Introduction

The FirewallFirewall Sorcerer burns foes to a crisp, leaving only ashes and scorched ground behind. This is your Sorcerer leveling guide for Diablo 4, with the maximum Skill Point allocation at Level 50. Let us go over the build mechanics, character progression, and playstyle!

The Firewall Sorcerer deals Burning Damage to eventually melt enemies with Damage Over Time (DoT). This build utilizes a “fire and forget” playstyle, casting FirewallFirewall to build fatal damage and moving on.

FirewallFirewall excels at killing large groups of enemies, but can struggle to kill tougher elites and bosses, especially if they tend to move around often. Alternatively, check out our Chain Lightning Leveling Guide for the best build to start a new Sorcerer character.

Once your Sorcerer character reaches Level 50 or enters World Tier 3, switch to the Endgame Guide for Firewall Sorcerer to continue this build.

Season of Blood

Season 2 Patch Updates

The following list details the changes in the Season 2 Update (Patch 1.2.0) that may pertain to leveling a Sorcerer character.

  • Resistances now stack additively and no longer become less effective with each additional source, while also contributing their full value to Non-physical Damage Reduction. Resistance values on equipment, Elixirs, and Paragon have been increased to more easily reach the new 70% cap. Furthermore, Intelligence now gives +0.025% All Resistance per 1 Intelligence instead of 0.05% All Resistance to compensate.
  • Increased Critical Strike / Vulnerable Damage affixes are now additive with other damage increases instead of being multiplicative. This change is a nerf to make Critical Strike Damage and Vulnerable Damage comparable to other damage increase options. All classes are affected by this change, therefore it doesn’t necessarily make Sorcerers weaker compared to other classes.
  • Armor no longer contributes to Non-physical Damage Reduction and now only reduces damage against Physical damage.
  • +% Total Armor affix has been increased by 160%.
  • Aspect of DisobedienceAspect of Disobedience – Armor % value has been increased from a maximum of +30% Armor to +66% Armor.
  • Supreme Unstable CurrentsSupreme Unstable Currents – Additional functionality added to make Crackling Energy pulse 25% faster while Unstable Currents is active.
  • Potent WardingPotent Warding – Resistance to All Elements increased to +3/6/9% from +2/4/6%.
  • Align the ElementsAlign the Elements – Bonus now persists for 2 seconds after taking damage.

Best Vampiric Powers Tier List for Sorcerer Leveling

The Season 2 theme introduces Vampiric Powers that provide build-altering bonuses. Spend Potent Blood, acquired from vampiric enemies, to unlock and upgrade Vampiric Powers. Make sure your equipped Chest Armor, Pants, Gloves, Boots, and Helm contain the appropriate Pacts (Ferocity, Divinity, and Eternity) that match the activation costs listed on the powers.

A Vampiric Curse status effect has been added to complement the new powers: Killing an enemy affected by your Vampiric Curse stores their soul. Casting a Defensive, Macabre, or Agility Skill will unleash stored souls to attack nearby enemies. You can hold up to 8 souls.

Listed below is the Vampiric Power Tier List for Sorcerer leveling, ranked by importance. Stat values displayed reflect maximum Level 3 Vampiric Powers.

  • Major Vampiric Powers (6 Pacts Required):
    1. Metamorphosis (2 Ferocity, 2 Divinity, 2 Eternity): When you Evade you turn into a cloud of bats, becoming Unstoppable for 4 seconds. Enemies along your path take 160% Physical damage and are inflicted with Vampiric Curse.
    2. Moonrise (6 Ferocity): Hitting an enemy with a Basic Skill grants you 4% Attack Speed for 10 seconds, stacking up to 5 times. Upon reaching maximum stacks, you enter a Vampiric Bloodrage, gaining 160% Basic Skill damage and 15% Movement Speed for 10 seconds.
    3. Accursed Touch (6 Divinity): Lucky Hit: Up to a 44% chance to inflict Vampiric Curse on enemies. Enemies with the Vampiric Curse have a 15% chance to spread it to other surrounding enemies. Accursed Souls deal 200% increased damage.
  • Minor Vampiric Powers (1–3 Pacts Required):
    1. Anticipation (1 Divinity): Your Ultimate Skills gain 20% Cooldown Reduction. Your Ultimate Skills gain 12% increased damage for each nearby enemy affected by your Damage Over Time effects.
    2. Prey on the Weak (2 Ferocity): You deal 16% increased damage to Vulnerable enemies. Enemies are Vulnerable while affected by a Vampiric Curse from your other Vampiric Powers.
    3. Domination (1 Ferocity): You deal 24% increased damage to enemies who are Stunned, Immobilized, Frozen, or Feared. If they’re also Injured and not an Elite, they’re instantly killed.
    4. Sanguine Brace (1 Divinity, 1 Eternity): When you kill an enemy, Fortify for 6% of your Base Life. While you have more Fortify than half of your Maximum Life, you gain 8% Critical Strike Chance.
    5. Hectic (3 Divinity): For every 5 Basic Skills you cast, one of your active Cooldowns is reduced by 2 seconds.

Mechanics and Playstyle

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 Fire BoltFire Bolt and InfernoInferno.

With enough damage, weaker enemies can be dragged through Firewalls while you move forward to the next group of enemies. Freeze tougher opponents, or run circles around them, to keep them from moving out of multiple Firewall placements.

Damage Rotation

Optimize DPS with the following rotation.

  1. Cast FirewallFirewall under enemies.
  2. Cast Frost NovaFrost Nova to Freeze enemies while they are standing in multiple FirewallFirewall placements.
  3. If needed, use InfernoInferno to group enemies up and freely spam FirewallFirewall.
  4. Spam Fire BoltFire Bolt to regenerate Mana.

Enchantment Slots

The Specialization of the Sorcerer can be unlocked at Level 15. Complete the Legacy of the Magi questline as soon as possible to gain access to your first Enchantment Slot, and then assign FireballFireball for group clearing. Once you unlock the second slot at Level 30, assign FirewallFirewall to it.

Gear Choice and Stat Priority while Leveling

Make sure to pick up all Rare equipment drops that may be upgrades while you are leveling Firewall Sorcerer. Save Legendary items with useful aspects in your stash to be used later for extraction and imprinting onto well rolled Rare items.

When comparing weapons with similar item levels, Two-Handed Staves are preferred over Wands for higher damage per hit while leveling.

Stat Priority List

Listed below are the affixes to prioritize on gear for Firewall Sorcerers. 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 or other character stats. Bolded stats are the most important and sometimes vital for the build to function properly.

Season 2 Update (Patch 1.2.0): Critical Strike Damage and Vulnerable Damage affixes are changed to be additive with other damage increases. All additive damage increases of the same amount are equal in value, as long as their conditions are active.

Legendary Item Aspects and Codex of Power

Aspects found on dropped Legendary Items have stronger effects than those applied from the Codex of Power. Additionally, it is important to know that certain Aspects can only be obtained by finding them on a legendary item, and are not accessible through the Codex of Power. Extract Aspects from unusable Legendary Items to imprint them onto well-rolled Rare Items. Avoid imprinting valuable extracted Aspects onto weapons, because weapons they get replaced often while leveling.

We have a dedicated in-depth Aspect and Codex of Power guide that you can check out for more information.

Listed below are the Aspects found on Legendary items that are important for the Firewall Sorcerer leveling build. They are listed in order of priority.
