^ describes each classic stat and its effects.

Wisdom (WIS)

Affects: Caster mana amount (mana pool) for Clerics, Paladins, Druids, Shamans and Rangers.

Max (cap): 255?

Brad McQuaid: "WIS: affects the amount of mana the priest classes have, also rangers; also affects how quickly you can learn many skills if your wisdom is higher than INT. "[5]

"The same effect as intelligence for the deity-based magic users: Cleric, Shaman Druid, Paladin and Ranger. The higher your wisdom, the more mana you get for each level. Very important for the deity-based magic users, but much less important for everyone else. The higher value of intelligence or wisdom is used to determine how quickly you will learn most of your skills, which makes having one or the other high useful for all classes."
