A Storm Cloud is a cloud that has thunder and lightning bolts coming out of it in the Killerwatt Plane and in Zanaris. It is found in Zanaris as a mini random event.
Storm Clouds in the Killerwatt Plane move around like NPCs, although players cannot interact with them whatsoever. Killerwatts sometimes hide and "disappear" under these clouds while a player is attacking them. Even though they cannot be seen under the Storm Clouds, players can still attack and deal damage to the Killerwatts.
