Not really. What Wisdom does is grant extra priest spells to Clerics and Druids (not Rangers), and contributes to the Lore score with Intelligence. However, if your divine caster theoretically has a Wisdom score below 13, then he/she will suffer a penalty to spell casting, in increments of 5% from 50% at 3 WIS to 5% at WIS 12. Above 12 WIS there is no penalty. Lore bonuses begin at WIS 15 (nothing until then). Bonus priest spells begin at WIS 13, so the higher the better.
