How's this for a starting point.
Cost 10
Healing 1d6 (max. Healed Points: 6), Reduced Endurance 0 END (+1/2), Persistent (+1/2), Variable Effect All Characteristics Simultaneously (+2) (40 Active Points); Extra Time 5 Minutes (-2), Self Only (-1/2), Always On (-1/2)
This would heal 1d6 Character Points Worth of every Characteristics every 5 min.
OR we could make it cheeper and do this.
