For the premier, I've decided to be utterly self-serving and offer up an idea I'm toying with for my Pulp Fantasy D&D project. As things stand now, I'm working under the assumption that the Cleric will be folded into a broad Magic-User "meta-class," becoming an example of one approach to the wielding of arcane powers. The traditional Magic-User, which is to say, the pointy hatted guy with a long beard, will become the Wizard, an example of another approach to magic. The Wizard's spell list will be like that of the OD&D M-U, while the Cleric (I considered calling him the "Priest," but am not sure I like that) will be that of his OD&D namesake.
Under this scheme, the Wizard's approach is all about the harnessing of power through the force of one's own will. Even when used for good, this is a dark, selfish path that slowly warps and twists the Wizard's body and (often) mind. Consequently, every time a Wizard gains a level, he must roll on the following table to see what, if any, price he must pay for his continued meddling with Things Man Was Not Meant to Know.
1D20 Roll (Any result achieved more than once is ignored, unless the given affliction is broad enough to admit multiple examples):
- Wizard's hair turns white or falls out completely
- Wizard acquires a pallid and/or waxy complexion
- Wizard is wracked with a incurably phlegmatic cough
- Wizard acquires a strange obsession
- Wizard experiences periodic hallucinations
- Wizard develops a limp in one leg
- Wizard develops a facial tic
- Wizard exhibits sores/boils on his skin
- Wizard periodically breaks into fits of uncontrollable laughter
- Wizard's nose begins to rot away
- Wizard loses the senses of taste and smell
- Wizard develops an allergy to a common food, animal, or object
- Wizard's lips crack and bleed
- Wizard weeps tears of blood
- Wizard's eyes either bug out or sink deeper into their sockets
- Wizard's arm or hand withers, becoming largely useless
- Wizard's finger and toenails grow at a prodigious rate
- Wizard's spine twists
- Wizard's body is periodically wracked with spasms or seizures
- Wizard develops webbing between his fingers and toes
The above list is partially inspired by the effects of Taint listed in the 3e version of Unearthed Arcana, a book I consider to be a very fine one, even if my love for 3e itself is less than enthusiastic.
