Skill Tree Points and Skill Bar
Skill Bar Setup for Fireball Sorcerer (order does not matter)

The following table shows the order in which to allocate your Skill Points while leveling with the Fireball Sorcerer build. You gain 59 points at Level 60 and 12 points from Renown, for a total of 71.

Important Respect Step: After obtaining Enlightenment, reallocate 3 Skill Points invested into Fire Bolt nodes into Frost Bolt, Enhanced Frost Bolt, and Glinting Frost Bolt. The change to a Frost Skill allows you to quickly gain Enlightenment stacks when it is alternated with other Skills.

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 additional AoE explosions to clear groups of enemies. Once you unlock the second slot at Level 30, assign HydraHydra to it for more spawns.

Higher Tier Aspects with more potent effects can be found on dropped Legendary Items. Salvage unwanted Legendary Items at the Blacksmith to unlock these Aspects in the Codex of Power, and then imprint them onto well-rolled Rare or Legendary Items. Check the in-depth Aspect and Codex of Power guide for more information.

Aspect of Elemental ConstellationAspect of Elemental Constellation is the most beneficial aspect that can be found on Legendary Item drops. If you are lucky enough to find the aspect with a decently rolled value, imprint it onto a Staff to double the dagger damage.

Listed below are the Aspects found on Legendary Items that are beneficial for the build while leveling, in order of importance. Check the endgame guide for the Fireball Sorcerer for the best-in-slot Aspect setup.

Weapon Gems: Sapphire for increased Vulnerable Damage.
Armor Gems: Topaz for Intelligence.
Jewelry Gems: Any Resistance Gems needed or Skull for Armor (up to the 1,000 Armor cap).
