Wisdom

Wisdom is your character ability to learn/discover new things, locations and skills. A high wisdom skills does not necessarily measure your characters intelligence in any way, but the two skills do play a vital role with eachother. A high Intelligence but low Wisdom skill will result in your character being only effective in a civilized setting and becoming incredibly ineffective out in the wildlands; the reverse is also true. Wisdom is incredibly important for Rangers/Pirates and Spellweavers. It is also further necessary to have a higher wisdom skill if your character is using survivalist as a sub class.

As an example, a character with a low wisdom skill has a much lower chance of finding/identifying tracks/ruins or practically anything new on the road or in the city.
