Ummm...Wisdom...useless...+1 to perception, sense motive, will save (which is used to oppose the intelligent weapon if it tries to dominate you), in addition to all of the other skills it boosts. Wisdom is very useful.
But I will say that it would be nice to not worry about disarming against you. Even if the enemy succeeds you still have you peck attack. Which is kind of awesome to think of.
The oracle is an interesting concept. An oracle of war starting with a Falcata or elven curve blade. That can make an amazingly powerful damage build. Have only healing/buff spells and you are a great support/secondary damage character.
