Obby is an experienced builder There is no limits to what Obby can build Obby might go insane at times, when he goes insane he will build dangerous things and throw it at people If one were to refuse to build with Obby, he would force them to build with him by filling their brain with the skills needed for building, overriding their thoughts into making them want to build with Obby, and then bringing them to a construction site where they will build with Obby for eternity (pfp was drawn by me)
