Asthma

With Asthmatic trait there is around 0.03% chance per turn that asthma attack happens (the chance is raising with stimulation level). If character has an inhaler and is awake and not underwater, then (s)he will automatically use it to suppress attack. In other cases (s)he gain disease for 50-200 turns (and wake up if was sleeping, or lose half of the oxygen if underwater).

Asthma attack decreases character's speed by [duration / 5], strength by 2, and dexterity by 3.

If duration is over 800 turns disease displayed at @-screen as "Heavy Asthma". Character will die if duration crosses over 1200 turns.

Beside an inhaler, asthma attack can be removed with royal jelly.
