Also, stat adjustments can't easily happen, because it breaks character legality, and you wouldn't be able to log in. To my knowledge a stat adjustment has only even been considered for one character, and that was a single point, and it was for an epic character.
Now, one thing you could do if you want stump to become a cleric is to dump every new stat point you get (1 every 4 levels) into Wisdom. This would truly require you to quite literally develop stump into a cleric, as it would take several points in Wisdom for him to be effective asa cleric.
