Healing Devotion( Complete Champion, p. 59)
You can heal damage faster than normal.
Once per day, you can gain fast healing 1, +1 for every five character levels you possess (maximum fast healing 5 at 20th level). This effect lasts for 1 minute. You can activate this feat as an immediate action or, if you have a daily available, it automatically activates if you are reduced to 0 hit points or below (but not killed).
As a full-round action, you can transfer this ability to a willing recipient as a touch spell. Doing so counts as one daily use of the ability. You can select this feat multiple times, gaining one additional daily use each time you take it. If you have the ability to turn or rebuke undead, you gain one additional daily use of this feat for each daily turn or rebuke use you expend.
