I picked up a geerlok, 40p Xgoeny, to help with my training and after I don't know how may attempts and a probably 20kp I didn't go up one level with the geerlok! I had more success but not more skill levels. So I put it away, saved up more plat and went up 3 levels in less than 5kp. I am either the most unlucky halfling around or you can't increase skill levels with it.
