Area of Effect:  The priest plus one other creature touched

This spell allows the priest to give up some of hit points to another character in order that he is be better capable to complete a quest. This is not current, but maximum hit points. The condition is reversed when the character returns from the quest successfully. If the character fails, the hit points return to the priest at the rate of 1 per week.
Here's an example: suppose a high level priest (with 78 HP) wants Sir Belvedere (80 HP) to retrieve a magical mace that was stolen. Sir Belvedere agrees, but only if the priest sacrifices 70 of his hit points, to ensure good faith and to help complete the mission. The priest agrees, and Sir Belvedere goes out in search of the mace. At this point Sir Belvedere effectively has 150 HP, and, for all intents and purposes his maximum hit points is now 150. Likewise, the priest's maximum hit point total is now 8.
Now suppose Sir Belvedere is successful in his mission. When he delivers the mace to the priest, they both immediately return to their normal maximum hit point value, although perhaps not their current hit point value, if Sir Belvedere is wounded. Current damage to the spell recipient is split evenly among the two when hit points are returned.
Now suppose Sir Belvedere was killed before the mission was complete. That means that the priest will have to wait 70 weeks until he returns to his normal maximum hit point total.
