A cleric is someone in service of a higher power, a god, a force of nature, an ideal. What vision do we summon when clergy becomes the topic? Is it an old man in brown robes with a ring of hair around a bald patch atop his head that spends his life in cloistered prayer? What about the merry Friar Tuck from Robin's band of thieves that never met a bottle he didn't warm up to? For some, the cleric is simply the white collared man in black that sermons over his flock like a shepherd to the lamb on Sundays.
No matter what or who you think of as the cleric you can be certain that you haven't thought of everything.
This great guide won't tell you everything you need to play a great cleric, but it will help you to get started.
