Build Mechanics

The Fireball Sorcerer launches fiery projectiles that explode on impact. Fireball excels at dealing area damage to groups of enemies after vortexing them with Raiment of the Infinite, or the Noc Kry Runeword.

Aspect of Elemental Attunement is often activated due to the area damage of Fireball with decent Lucky Hit Chance, rapidly resetting Ice Armor, Flame Shield, Teleport, and Frost Nova.

Ice Armor grants a massive Barrier, increased Armor, and Unstoppable. The benefits can be refreshed every second when hitting enough enemies for a significant boost to survivability.

Frost Nova generates Mana and applies Vulnerable to enemies through its modifiers. The Skill can be cast from the Skill Bar or triggered through its Enchantment effect.

Teleport is an effective Mobility Skill and, more importantly, pulls enemies towards you through Raiment of the Infinite. Group enemies together to enhance area damage explosions from Fireball. Blaze consumes Overpower charges generated by the modifier on Flame Shield to spam Teleport.

Inferno overflows Overpower by 2 to stack the unique effect on Emberfury or reset the Cooldown of Teleport (Blaze). The Cooldown modifier allows Inferno to be cast frequently to speed-farm activities.

Rotation and Playstyle

Use the following rotation to optimize the playstyle:

Cast Teleport to traverse and/or group up enemies with Raiment of the Infinite.
Spam Ice Armor and Flame Shield. These buttons can be held down if you tap Fireball.
Vortex large groups of enemies with Inferno.
Cast Frost Nova to Freeze enemies and apply Vulnerable, if it is not already triggered by its Enchantment effect.
Spam Fireball to deal damage.
