Trapsmith

"Don’t touch that."

Some things you just don’t fight. To take on adversaries that have superior strength, cunning, or resources (or all three), you need to remove their advantages. Such an alternative approach is the job of a trapsmith.
    Humanoids have been building traps since the earliest times, developing techniques to take down big game for food and clothing. According to loremasters, goblin tribes were the first to perfect this kind of hunting. They were able to obtain and store more food than their competition, allowing them to survive harsh winters and increase their numbers. Many years later, other races came to appreciate the ingenuity of their counterparts—mainly through direct interaction with goblin traps.
