Skill Feat Specialty Crafting

Creating all sorts of minor inventions scratches your itch for problem-solving. Your engineering skills take a particularly creative bent, and no one know what you’ll come up with next. It might be a genius device with tremendous potential... or it might explode.

Choose two ability boosts. One must be to Dexterity or Intelligence, and one is a free ability boost.

You’re trained in the Crafting skill and the Engineering Lore skill. You gain the Specialty Crafting skill feat.
