An item used to create a Mercenary. They can be obtained by stealing from a mob of 3 Booteles or a mob of 1 Booteles and 2 Bootes on floors three through five of Blue Garden. Also found by killing them but is not very likely to happen. This item can only be used for male children.
Note: The mob of 3 Booteles will have all Monsters at level 16. However, there seems to be a duplicate mob that will only allow you to steal a Potion. Also, the Manual appears to drop most often from the BootelesC, so save it for your thieving.
