Syntax: cast 'infectious cloud'
Necromancers can release an infectious cloud into the air, which when
inhaled by others in the room, will cause recurring nausea and bodily harm.
Once infected, harm will be inflicted upon the victim every 3 seconds. A
maximum of 10 infectious clouds can be created by the same caster per area.
Infectious cloud will not cause harm to the caster, pets, or peaceful
players. If you are in a PK house and a player in a different PK house
enters the room, he or she will be wounded by this spell.
There is no cooldown or lag after casting this spell.
