Drained

A drained creature has had their vitality or even their core abilities decreased temporarily, such as by disease or a shadow's sapping touch. When a creature is drained, either their hit point maximum or one of their ability scores is temporarily lowered.

• If a creature suffers hit point drain, their maximum hit point total is reduced. Their hit points cannot be higher than that temporary maximum, and if their maximum hit point total reaches 0, they die. A creature that has had their hit point maximum reduced is more likely to die to massive damage. As normal, if an attack reduces a creature to 0 hit points or hits a creature with 0 hit points and deals excess damage equal to or greater than their new hit point maximum, they die.

• If a creature suffers ability score drain, one of their ability scores (such as strength) is reduced temporarily. Everything affected by that ability score is also reduced accordingly.

• The drained condition is always removed at the end of a long rest, unless caused by an effect (such as a disease) that says otherwise.
