The Tinker!

Tinker
Requirements: Dex 9
Prime Requisite: Int
Hit Dice: d6
Humans who become tinkers are fascinated by the way things work, especially clockworks. They enjoy creating wondrous mechanisms to delight and amaze. There are a select few who thrill to see there work used in new and different ways, possibly in dangerous circumstances. Tinkers learn and create schematics that allow them to create these mechanisms, and as they level, the designs become more and more complicated. Their armor is limited to leather and weapons they have some skill in are daggers, blunt weapons, and bows. Magic items a tinker may use; armor, weapons, rings and potions. Also, they are able to pick locks, find/remove traps, and hear noise as a thief of the same level. At the upper levels, they are able to create amazing mechanisms that can delight and thrill onlookers.
