The base version of the spell restores 15 Health & Stamina Points at a cost of 7 Mana Points (MP). The amount of health and stamina restored increases with training in Spiritual Lore, Blessings, but the mana cost does not increase.
The spell will also impart a health and stamina regeneration bonus to the caster, equal to 10% of his maximum stamina, with a minimum of 1. This bonus is reduced by 1% of his maximum stamina every 30 seconds, until it reaches 0% after five minutes.
When EVOKEd, Rejuvenation will restore health without triggering the stamina restoration/buff mechanic.
Rejuvenation in its most effective form may only be cast once every 5 minutes. Subsequent casts within the same 5-minute period will only return health (including lore bonuses) but no stamina.
Training in Spiritual Lore, Blessings increases the rejuvenation gain by +3 HP/stam per seed 1 summation, starting at +3 HP/stam at 1 rank to a maximum of +57 HP at 190 ranks. This effects the once every 5 minute hit of health + stamina. The stamina regen isn't impacted by lore.
