Rapture

Rapture is a specialization ability for Discipline priests, available at level 50. It removes the cooldown on Power Word: Shield for 8 seconds.

Tips and tactics

 * Using Rapture while soloing is not recommended. It can still be useful as a last resort for keeping yourself alive while attempting to run away, however, especially if you've talented into Body and Soul.
 * Rapture is intended to be used in a group or raid setting. It is exceptionally useful for shielding party members if incoming heavy AoE damage is expected.

Previous bug

 * Up to and at least through Patch 3.0.8 this ability appeared to return mana based on the priest's target and not the priest making this ability mostly useless (except mildly helpful when heal/shield a paladin or feral druid).
