“This class of character bears a certain resemblance to religious orders of knighthood of medieval times.” “A cleric is dedicated to a deity, or deities, and at the same time a skilled combatant at arms.” They may be any Alignment except TN depending upon the alignment of the deity the cleric serves. “All clerics have certain holy symbols which aid them and give power to their spells.” “All are likewise forbidden to use edged and/or pointed weapons which shed blood.” “All clerics have their own spells, bestowed upon them by their deity for correct and diligent prayers and deeds.”
The main purpose: a cleric serves to fortify, protect, and revitalize. This is demonstrated by the spells available. They have a limited number of attack spells, some are reversals of curatives. “All spells must be spoken or read aloud.” Ability to wear armor, carry effective weaponry, and engage in hand-to-hand combat (melee) with a reasonable chance of success.
Ability to Turn away (or command into service) Undead and less powerful Demons and Devils. These include: ghasts, ghosts, ghouls, liches, mummies, shadows, skeletons, specters, wights, wraiths, vampires, and zombies (see MM). The matrix is for the DM only. Typically effective against undead not greater in HD than cleric’s level. Demons and devils require a high level cleric.
“Only humans will normally have clericism as their sole class; they are the only clerics with unlimited advancement.” Combat is in 3 steps of ability. Saving Throws in 3 steps of ability too. Magic Item use includes: most potions, clerical and ‘protection’ scrolls, most rings, some rods, staffs, and wands, many other magical items, and all non-edged, non-pointed weapons; also all magical armor, and shields.
8th level = Patriarch or Matriarch. The cleric automatically attracts followers if a place of worship is established. 2000+ square foot floor with alter, shrine, chapel, etc. These followers are fanatically loyal and serve without pay as long as same deity and / or alignment does not change. They number between 20-200 (2d10 x 10). Some will be men-at-arms; the type and number of all are relayed by the DM at the appropriate time.
9th level = High Priest. The cleric has the option of constructing a religious stronghold. The fortification must contain a temple, cathedral, or church 2500+ square foot ground floor. It may be a castle, monastery, abbey, or the like. It must be dedicated to cleric’s deity. Construction cost is ½ because of religious help. If the cleric clears the surrounding territory and humans dwell within, there will be monthly revenue of 9 SP / inhabitant from trade, taxation, and tithes.
