"Applies 2 stacks of damage over time effects instead of 1."
Notes
The actual range of Corrosive Cloud is slightly smaller than the visual effect would imply. As such, enemies can be on the fringes of the cloud without being afflicted by it.
Corrosive Cloud is unique in that it can only have a maximum of 4 affixes on the skill no matter the tier.
Instead of increased damage with higher gear levels, this skill grants passive damage reduction to the player.
Because of its tags, it can only get three non-starred affixes at the same time:
Lightning AoE.
Ammo back on use.
"Oil on Use" or "Fire on Use", which are mutually exclusive.
