Rejuvenate

Rejuvenate is an ultimate ability associated with the Defence skill. It requires 52 Defence and a shield. When activated, Rejuvenate restores any drained stats to their normal levels and begins healing the user by 40% of their maximum life points in a series of rapid healing hitsplats, over the course of about 10 seconds. About 4% of the user's maximum life points are restored each second. The stat restoration occurs at the end of the ability's duration, and does not affect prayer.

Because of its strong healing power, Rejuvenate could potentially replace the need for food, or any other source of healing, during extended combat trips. Situations where Rejuvenate may be useful include Slayer assignments, player-vs-player activities, the earlier waves in the TzHaar Fight Cave and fighting bosses. However, players must bring and/or use a shield in order to activate Rejuvenate, and it may only be used once every 60 seconds, and only with full adrenaline. Moreover, removing the shield will instantly end the effect, which will also cancel the stat restoration at the end.

Trivia

 * Rejuvenate bears a strong resemblance to the late special attack of the enhanced excalibur, as it heals the user over time. The strongest version of Excalibur heals 400 life points, mirroring the 40% healing of Rejuvenate.
 * When first released into the combat beta, Rejuvenate could cure poison. However, this ability was removed sometime in October 2012.
