This guide covers a basic Fire Wall setup that can challenge Diablo 4's early endgame with relative ease, including Helltides, low-tier Nightmare Dungeons, and Diablo 4 Gold every open-world activity in World Tier 3. The general setup and playstyle will remain more or less the same on Torment mode, but expect to run into more difficult encounters by then.

Fire Bolt is only here to unlock the rest of the skill tree. The build's main damage dealers are Fire Wall, Inferno, and, to some extent, Frost Nova. Slot in Ice Shards in an Enchantment Slot to make Frost Nova shoot damaging projectiles every time it freezes enemies. These shards can crit and apply Lucky Hit effects.

Usually, players will just be spamming Fire Wall as they run around a dungeon. However, once bosses or Elites enter the scene, players should cast a few Fire Walls under them before unleashing Inferno and Frost Nova. Stack as many Fire Walls under the enemies before Inferno expires to deal as much damage as possible.

Fire Wall Enchantment provides a chance to spawn even more Fire Walls on a Lucky Hit. Stack enough Lucky Hit Chance and watch the screen be engulfed in flames.

This skill setup balances defense and offense. Note that while Fire Wall cannot critically hit, the Burning Instinct Legendary Node will let all Burning damage scale off Critical Strike Damage. This Paragon Node is mandatory in order to make Fire Wall synergize with Esu's Ferocity and Devouring Blaze.

Players will likely be in close range while playing this build, so try to keep every nearby enemy ablaze to enjoy Warmth's health regeneration. Much of the player's survivability will still come from their Defensive skills, however.

Much of the build's damage will come from the Conceited Aspect as well as the Barriers provided by Ice Armor and Protection. Edgemaster also works very well with Supreme Inferno's Mana cost reduction, allowing the Aspect to buff every Fire Wall cast while the giant fire snake is on the field.

Searing Wards isn't completely necessary, but it's nice to Diablo 4 Items have in the later stages of the game where projectiles can be an issue. Every fifth Fire Wall will destroy incoming projectiles, nullifying the threat posed by many demons and Elite powers.
