My answer to the “Intelligence-based, half-casting, crafting class”. Build mundane objects at lightning speed using Construction and turn them into pseudo magic items with your Affect Engines.
There are two versions of my class. Both versions will be reproduced here. There is the Original Version (hereby dubbed Original Tinkerer) which is approximately 10,000 words long and was formatted by me. Then there is the EN5ider version (hereby dubbed En5ider Tinkerer), which is 6,500 words long, to which I sold a 1 year license to (which has long expired). They are both excellent, and while the En5ider Tinkerer has more missing content than I would like, it also has a completely revamped Mechanic Subclass that rebalances the 20th level Mega-Robo capstone feature into a 10th level feature, which means you get to control your giant robot suit much sooner.
