Healing Penalties
 

So suppose Alice has been painfully injured by a horrible mean no good giant ape

The party has two clerics, Bob and Carol, who want to heal Alice

Bob heals Alice for the first time that day, so his next spell is at -3

Carol wants to heal Alice, is Carol at -0 (because she hasn't tried to heal Alice yet today) or -3 (because Bob already did once)?

Re: Healing Penalties
 

The description of Major Healing (Spells, 37) says that the penalty only accrues for the "same caster on the same subject." Thus Carol is at no penalty. This is true for both Major and Minor Healing. Great Healing, however, can only be cast successfully on a subject once per day no matter how many casters try.
