Mass Cure allows the priest to heal multiple party members within the area of effect.
In-game description Edit
|“|| Mass Cure|
When casting this spell, the priest must picture the faces of his/her fellow party members clearly and focus on the unity of the group. Upon completion, all party members within a 30-ft. radius of the caster are healed 1d8 + 1/level Hit Points. Curing is permanent only insofar as the creature does not sustain further damage; caused wounds will heal—or can be cured—just as any normal injury.
