The character’s lungs burn from acute smoke inhalation, and the character exhales wisps of smoke with every breath. The character suffers disadvantage to all Dexterity (Stealth) checks due to a constant, irritating cough brought on by this affliction.
As an action, the character may cough up a billowing
cloud of foul-smelling smog in a 10 ft. radius. This smog
heavily obscures the area, and dissipates after 1 minute
(or 1 round in a moderate wind). Once this ability has
been used, the character must finish a short or long rest
before it can be used again.
