Pathfinder: Tinker Plus
You're not just a Tinker anymore, you're the Tinker. The PRT rating scale isn't really set up to handle someone like you because it assumes that Tinkers will have specialties, and you don't. You are something never seen before; a genuine omni-Tinker, and one of truly amazing capacity. Your aptitude and intuition for all sorts of research, science, engineering, and design is absolutely unbelievable. If a project is even halfway related to any of the "hard sciences" then you can get it done, and do so with a speed and efficiency that makes even experienced Tinkers working within their own specialities look like clumsy beginners. And you can rapidly reverse-engineer other technology given sufficient opportunity to study it, however complex or esoteric it might be. You can even study and analyze exotic and anomalous phenomena, such as cape powers in action, to hopefully gain inspiration for new Tinkertech. You have a volume knob in your head for making your designs either easily reproducible by mundane methods or totally blackboxed vs. any reverse-engineering or anything in between. You can perform what would have required "clean room" levels of precision assembly for mundane engineers with ordinary tools and under rough conditions. Troubleshooting or repairing tech that you already understand is a job you could practically do in your sleep, and anything you build or overhaul is maintenance-optional. With time and practice your Tinker abilities can improve and grow indefinitely, without any upper limit. You can't do things like 'perfected social sciences' or 'auto-win personal interaction methodologies', though. That sort of thing is for Thinkers, not Tinkers.
