Well it's not a weapon for every follower of Aeredin. Certainly, high prerequisites are a must. After all. Power to heal is granted to very few. And it does not have to cast heal, or there could be several levels of it. One casts cure minor, next casts cure serious, third casts cure critial, and last cast heal.. Should probably be available to serious followers of Aeridin. Servants that have proven themselves on the path of light. No mere worshipper should be able to wield such power..
