A condition is a temporary effect imposed on a creature. Conditions can happen under many circumstances, such as eating a poisonous plant or being the target of a spell. Conditions can aid or impair a creature, and some may do either or both depending on the circumstance.
Conditions don't stack, so getting hit with multiple instances of the same condition does not increase the effect. Some conditions have similar effects, such as frozen and slowed, which would stack. In addition, some conditions have multiple severities. Only apply the highest severity when a creature is affected by multiple severities of the same condition.
