Blast Rain is a bow attack skill that fires an arrow up in the air, which splits and rains down in a series of four 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 and additional projectiles), 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

Place into an item socket connected to a socket containing the Skill Gem you wish to augment. Right click to remove from a socket.).

• The delay between using the attack and the first explosion is 600ms that can be modified by both attack speed and projectile speed. There is also the falling animation that takes 270ms (a 67.5ms delay between each blast), which is fixed and cannot be modified.

• By default explosions fall in a 24 radius area and may overlap in a 3-unit circle.

• Tooltip damage: The damage dealt and DPS values shown on this ability's tooltip only indicates the damage from a single explosion.
• Since Blast Rain hits multiple times in sequence per attack, it is a great trigger for things like Cast On Critical Strike SupportCast On Critical Strike SupportCritical, Support, Spell, Trigger
