Revive

Reviving is an action that can only be done on dead hatchlings and dead adults. It is when you use a magic spell to attempt to revive your dragon.

Three things can happen:
 * 1) The revival will fail and the dragon is dead for good. ("You attempt to revive the dragon using magic, but instead its body disintegrates.")
 * 2) The revival is successful and the dragon returns to its former state.
 * 3) The revival is only partially successful and the dragon turns into an Undead Dragon, also known as a Zombie Dragon. ("You attempt to revive the dragon using magic, but something goes wrong and instead it becomes a zombie.")

Except on Halloween, reviving is unlikely to work. The chances of getting an Undead Dragon were believed to be 1 in 100 on any day of the year besides Halloween. It is now confirmed that it is impossible to get Undeads on any day of the year besides Halloween, which has a chance of 1 in 2.
