Wisdom, WIS in your 'score', represents your character's wisdom and
ability to incorporate learning.
Wisdom reflects a character's willpower, insight, and intuition. A
character is much more aware of his surroundings with higher wisdom.
Among other things, wisdom affects:
> The number of practices a character gains each time it levels
> The mana a character gains each time it levels, though
intelligence affects this much more heavily
> The ability to remove a trap or poison a weapon
> The saving throws versus wands, spells, and staves
Wisdom is the prime attribute of the Druid, Cleric, and Augurer.
Wisdom is the secondary attribute of the Mage, Ranger, and
Paladin
