You're the archetypal gremlin, the type most people picture when they think "gremlin." As such, you know how to make things, and you know how to break things. You become trained in Crafting (or another skill if you're already trained in Crafting). You gain the Snare Crafting feat, and you learn the formulas for six common 1st-level snares instead of four and can remember snare formulas without needing a formula book for them.
