Blast Rain is a bow attack skill that fires an arrow up in the air, which splits and rains down in a series of explosions over an area.

Skill functions and interactions

• Damage conversion: 100% of the player's physical damage will be converted to fire damage. Like all converted damage, the fire portion of Blast Rain's damage will be modified by both fire damage and physical damage increases.

• Projectile damage: Although Blast Rain does not fire projectiles (and therefore cannot benefit from projectile effects such as chaining), like any bow skill it does deal projectile damage and will be affected by any appropriate damage modifiers (such as Vicious Projectiles SupportVicious Projectiles SupportProjectile, Attack, Physical, Chaos, Support

• Area of effect: Explosions fall in a 24 radius area and may overlap in a 3-unit circle. This area is affected by modifiers to area of effect.

• Additional Projectiles: Each additional projectile adds an explosion to the attack.

• Animation speed: The delay between using the attack and the first explosion is 600ms, which can be modified by both attack speed and projectile speed. The falling animation takes 270ms and cannot be modified.

• Tooltip damage: The damage dealt and DPS values shown on this ability's tooltip only indicates the damage from a single explosion.
