Toxic Rain is a bow attack skill where the user fires multiple arrows in the air, which land and drop spore pods, dealing chaos damage over time and slowing enemy movement speed for their duration. The spore pods explode after a delay, dealing chaos damage.

Skill functions and interactions

The explosion of the Spore Pods counts as a hit, which allows for rapid application of "on hit" effects such as poison, or life and mana gain on hit.

Increasing the number of projectiles increases the number of pods you produce, thus increasing your damage.

Accuracy affects all hit portions of the skill but not the damage over time of the pods.

Sources of increased area of effect allow the damage over time from each spore to overlap. However, as of 3.14, this also increases the spread of the pods.

Spore explosions and arrows count as "kill with this weapon" but damage over time component does not.

Optimal Single Target Setup

Based on user testing, it is actually better for your single target damage to increase your area of effect by 39%.

The easiest way to obtain this is:

• 20% from bow Passive Mastery.
• 9-10% AoE mod on gloves/amulet.
• 20% quality on Toxic RainToxic RainAttack, AoE, Chaos, Duration, Projectile, Bow
