I trained him in many Jobs and learned things like Teleport, Math Skills, all Talk Skills, and Blade Grasp. Some say to use MP Switch, but I found that it's just as easy to use Blade Grasp or Auto Potion with only X-Potions. It's fun to use something like HeightPrimeNumberFrog and watch enemies get frogged. Also, I zapped EVERYONE BUT RAMZA in that Chapter One battle in Dorter. I used Bolt 3 and it zapped (and killed) everyone, including Algus and Delita!
