This guide will walk you through the Poe 2 trade essential aspects of creating a devastating Fireball Blood Mage, including skill selection, passive tree optimization, gear choices, and playstyle tips.

Why Choose Fireball Blood Mage?

The Fireball Blood Mage is a hybrid between traditional fire spellcasting and life manipulation mechanics. Unlike other mage builds that rely purely on mana, the Blood Mage converts health into offensive and defensive power, allowing players to maintain high spell damage while sustaining themselves through life leech and regeneration.

Advantages of this build include:

High burst and AoE damage: Fireball provides massive area-of-effect damage, ideal for clearing groups of enemies.

Life-based mechanics: Blood magic allows you to bypass traditional mana costs and synergize with health-leeching abilities.

Versatility in gear: The build allows flexibility in equipment choices, particularly focusing on spell power, spell critical, and life leech effects.

However, the build comes with its risks: it relies heavily on maintaining life pool management, as reckless health expenditure can quickly lead to death in high-level encounters.

Core Skills

The Fireball Blood Mage primarily revolves around the Fireball skill gem, a classic spell in Path of Exile known for its explosive damage radius and synergy with elemental damage bonuses.

1. Fireball

Fireball serves as your primary damage-dealing ability. It launches a fiery projectile that explodes on impact, dealing high area-of-effect fire damage.

Link with support gems for optimal performance:

Spell Echo: Casts Fireball twice in quick succession for double explosions.

Elemental Focus: Boosts elemental damage without applying debuffs, maximizing raw firepower.

Burning Damage Support: Increases burning damage over time, letting Fireball ignite enemies for sustained damage.

Increased Critical Strikes / Critical Damage Support: If opting for a critical-based approach, amplify Fireball's potential.

2. Blood Magic Support

The essence of the Blood Mage, Blood Magic allows you to cast spells by consuming life instead of mana. This gem is essential for maintaining Fireball usage without relying on traditional mana pools.

3. Life Leech / Life Gain on Hit

Blood Magic is powerful, but without a form of life recovery, it's a double-edged sword. Gems such as Life Leech Support or Vampiric Pact (if available in PoE 2) ensure you regain life with each hit or spell cast.

4. Defensive Utility

Spells such as Flame Dash or Steelskin can be linked with Blood Magic to enhance survivability. Flame Dash provides mobility for dodging dangerous encounters, while Steelskin absorbs damage upfront, giving you time to heal via leech mechanics.

Passive Skill Tree Optimization

The passive skill tree is where the Blood Mage shines. Key priorities include:

Spell Damage and Fire Damage Clusters

Maximize damage output by targeting nodes that increase spell damage, fire damage, and critical strike chances. Fireball benefits heavily from increased area-of-effect nodes as well, making it perfect for buy POE 2 Orbs clearing packs.

Life and Life Leech Nodes

Since Blood Magic consumes your life for casting, investing in life nodes is critical. Focus on life leech, life regeneration, and increased maximum life nodes to stay survivable in endgame content.

Critical Strike Clusters (Optional)

If building a crit-based Fireball, nodes enhancing spell critical chance and multiplier will significantly boost damage. Combine with increased critical strike support gems for explosive potential.
