Upon detonation the Cloud grenade releases a green corrosive cloud that lingers for several seconds, dealing corrosive damage to all enemies within the area regardless if they are resistant to corrosive damage. Enemies that are resistant to initial corrosion damage will still take damage from the cloud, but will not receive the usual damage-over-time effect that they would otherwise be afflicted with if they were not immune.
Unlike the Fire Burst Grenade, this grenade mod does not look as threatening and might give the player a false sense of safety which can cause players to damage or kill themselves by walking through the cloud.
Pandemic - Legendary grenade mod, it's a mix between the Cloud grenade and a Transfusion grenade that instead of healing, homes to other enemies and keeps doing it until the grenade expires.
The Cloud Grenade is obtained randomly from any suitable loot source.
