Reincarnation

Reincarnation allows the Shaman to instantly resurrect himself upon death with a percentage of maximum health and mana.

Improvements

 * Glyph of Renewed Life removes the need for Ankhs.

Tips and tactics

 * When you know you are going to wipe, find a safe place to die (where you will not aggro the mobs when you rez), wait for mobs to reset, Reincarnate, and resurrect the other players. This avoids the wait involved with everyone having to run back (and possibly re-clear trash).  Watch your cooldown, because the ability may not then be available in a boss fight where reincarnating may mean the difference between a win and a loss.
 * If you are out of mana, you can deliberately die and resurrect with 20 mana and health, and continue the fight. Obviously, this is not useful when soloing, as the mobs will immediately reset when you die.
 * If you reincarnate and die again you will take durability damage twice.
 * Dying will reset your threat. This is sometimes jokingly referred to as "the Shaman aggro dump".  Unlike Feign Death, it cannot be resisted.
