Transcendent Senses

At least 1 other feat that requires transcendence

You gain 30ft of truesight.   Additionally, when you attempt an ability check, you can choose to lower your maximum hit points by 2d6 points to immerse yourself in the realm of transcendence for a moment. While immersed in the realm of transcendence, you have advantage on your ability checks, and on a success they are completed in the span of 1 action.   For example, the forging of a master work could be completed in an instant, as could the creation of detailed schematics for a building, as well as the search for a specific book in an endless library.   Your hit point maximum that was lowered by this effect will recover by 1 point every time you finish a long rest.
