Continuing with my musings about spell casters, I was thinking about how the Cleric fits into Shatterworld.
Since it is intended to be a "low magic" setting, where the percentage of people who have ever actually seen a spell cast is very small, it seems that most temples would not have spell casting clerics. The "normal" priest does not cast spells. So either:
1) They aren't clerics
2) They are clerics who can't cast spells
3) They are clerics who can cast spells, but choose not to
My choice is to say that they aren't clerics, but simple priests. That is, "Cleric" is a specialty class, not unlike "Paladin". Just as the Paladin is a rarity among men who gets his healing abilities through pious devotion, so the Cleric is a rarity among priests. The Cleric's powers are derived through exemplary devotion to the gods.
When such a person enters a village, all who know of the Cleric's reputation will come flocking to touch the hem of his cloak, to beg for healing for their loved ones, or to merely stand in the awe of his presence.
A cleric who can heal wounds or cure poison or standard disease would be famous. A cleric who can cure blindness, cure permanent diseases such as leprosy, heal the cripple, or raise the dead would be legendary.
It is no wonder these "living saints" take to a life of wandering. The line of those waiting to be healed outside their temple would be endless.
