Certain abilities in Atas, detailed elsewhere in the rules, can cause your character to become poisoned or diseased. Both of these afflictions are effectively the same, and the terms are interchangeable. A poisoned furre loses 5HP per minute whilst out of combat, and 5HP a turn in combat.

Poison does not stack, thus a poisoned furre will never lose more than 5HP at a time, unless specifically detailed in the rules for the attack. A poisoned furre cannot be cured by healing spells, only by methods which specifically state that they cure disease/poison.
