Aging

Aging is a special ability of Ghost Dragons that takes effect after they have attacked target creature stack and before the stack has chance to retaliate. It causes maximum health of every unit in the target stack to be halved. The aging effect can only be removed with Cure spell, but it wears off after 3 turns. Any health already lost by the creature being aged will remain lost (ie, if an Archangel is on 200 health (that is, missing 50 health) and then aged, it will still be missing 50 health, putting it at 75 health. And when it wears off, or is removed, the same is true.)

Aging stacks multiplicatively with Poisonous, so a creature's health could potentially be quartered.
