Korthoth (kobold 1? artificer/ranger?)
Master of traps
Note: I just made him a hybrid because he doesn’t need all the artificer stuff, and ranger had a “trap” attack at 1st level. Maybe I should check through the rogue exploits too.
Korthoth loves traps in all forms. The rumor that he has booby-trapped his crossbow has never been tested, but he can certainly shoot traps out of it. Dissatisfied with traps that were fixed in place making them too obvious, he left his tribe to launch his own creations onto many battlefields and to find more to add to his collection.
