Wisdom rating will act much as does that for intelligence.
D&D Vol. I: Men & Magic, 1974
Helpful quote, I know. Besides acknowledging that wisdom is the prime requisite for clerics, along with some guidelines on how a wisdom score can be adjusted to affect a character’s overall experience point bonus, the above sentence is all the original three Dungeons and Dragons booklets ever said about wisdom. Despite my love for OD&D, that’s a pretty half-baked conceptualization for one of the three primary abilities. At least it was half-baked in its originally published form. It seems Gary Gygax just needed a mechanical parallel to the strength and intelligence prime requisites for fighting-men and magic-users, respectively. What wisdom actually measured had to either be deduced by the dictionary meaning of the word or ascertained in actual play with other players.
