3.23.0	Blast Rain:
3.22.0	Fixed a bug where weapon swapping to a melee weapon while Blast Rain projectiles are falling would add the damage from the weapon to the Blast Rain projectile damage.
3.13.0	Blast Rain
3.10.0	Fixed a bug which caused Blast Rain's tooltip to not update with additional arrows.
3.9.0	Blast Rain The Blast Rain additional blast Labyrinth enchantment can no longer be acquired from the Merciless Labyrinth. The Eternal Labyrinth enchantment now grants 100% chance for an additional blast (from 75%). Existing items are not affected.

Blast Rain

Blast Rain is a bow attack that fires an arrow into the air that 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), it deals projectile damage and will be affected by any appropriate damage modifiers (such as Vicious Projectiles 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 projectile falling 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 tooltip DPS only takes into account the damage from a single explosion.
