FEAT: Specialization

As an Engineer you sometimes draw inspiration from different sources for your creations or inventions, do ideas come to you after you've read a line of ancient scripture? What about the way the animals move or how the leaves and grass sway? Or even seeing the simple yet complex beauty of a cogwheel?

FEAT: Instruction Manual

You can study a robot, technological object, or technological trap within 30 feet as a move action and attempt a Intelligence (Engineering) check to identify it. If you succeed, you gain a competence bonus equal to 2 + your tier on attack rolls, combat maneuver checks, saving throws, and skill checks involving the studied creature, object, or trap, as well as a AC and saving throw bonus of the same amount against attacks from the subject of your study. This bonus lasts a number of rounds equal to your Intelligence modifier (minimum 1). If you study a new subject, you lose the bonus against the previous subject.

FEAT: Remarkable Discovery

During your time experimenting, you have made a most remarkable discovery. You can recreate what you have discovered to others, but selling your discovery will likely lead to it becoming commonplace. However small your discovery may be, it certainly doesn't stop individuals using nefarious purposes from finding out your secret.

Work with your DM to determine the details of your discovery. What specific materials do you need? What does it create?

As a pointer, remember this preferably should be small. Your discovery shouldn't be easy to make, and the larger it is the more work should be done to create it. Any clockwork devices or similar should be comparable to the Rock Gnome's in the original 5E Player's Handbook, any chemical reaction should not yield any net gain in wealth, any environmental discovery should be minor, and any special technique or method should not affect the stats of anything you are making. Making a larger effect should preferably be discussed with your DM.
