Ghost Construct
Create constructs up to 5 meters in diameter, that you can pass through at will. These will last forever, but there is a 20 minute recharge on the power. The constructs are indistinguishable, and form in about 1 second. These constructs will be made anywhere the user wants, in any orientation, within 1 meter of the user. They can also destroy their constructs at will in 5 seconds. The user needs to have observed something with at least two senses to construct it. Constructs cannot form multiple things at once. This works on how the user views the construct, so if they think it's multiple objects, it won't work.
This can be used to:
You get the idea. You can go off the grid, make hidden passageways wherever, make powerful weapons in a second, and vehicles for wherever you want to travel.
