Passive Tree:

• Starting from the Ranger side of the passive tree, grab life and damage nodes, along with bow nodes.
• As you progress through the tree, prioritize the Explosive Arrow keystone and take nodes that increase elemental and burning damage.
• Reach for the Marauder side of the tree to pick up more life and armor nodes.

Bandits:

Kill all the bandits for the two passive skill points.

Gems:

• Explosive Arrow (6L): Elemental Damage with Attacks, Burning Damage, Ignite Proliferation, Swift Affliction, Mirage Archer, and Greater Multiple Projectiles
• Frenzy (4L): Faster Attacks, Curse on Hit, Flammability, and Culling Strike
• Herald of Ash, Vaal Grace, and Anger

Gear:

• Weapon: Quill Rain or Lioneye's Glare (early game) and Equivalent Exchange (mid-game).
• Body Armour: Belly of the Beast or Loreweave.
• Head: Devoto's Devotion or Starkonja's Head.
• Amulet: Shaper Amulet with Burning Damage, Life, Elemental Damage with Attacks, and Resistances.

Flasks:

Atziri's Promise, Wise Oak, Quicksilver Flask of Adrenaline, Diamond Flask of Warding, and a Life Flask.

Playstyle:

• Place totems down with Explosive Arrow and have them attack before they explode, dealing massive AoE damage.
• Use Frenzy to generate charges and apply the Flammability curse to enemies.
• Utilize the Vaal Grace and Anger skills for additional damage and defense.
• Be cautious of reflect maps, as the build deals a lot of elemental damage.
• Avoid standing still for too long, as the build requires movement to place totems and attack safely.

In summary, the Explosive Arrow Champion Build is a powerful and rewarding character build that requires careful placement of totems and fast movement to succeed. With the right items and skills, this build can take down even the toughest bosses in the game. Good luck in the upcoming League!
