Trap Inspection

By channeling the arcane into your senses you gain an enhanced knowledge of any room you enter. While concentrating on the spell you gain these effects when you enter a room: (You know how high the ceiling of the room is, you know how thick the wall are, you can tell the material  the floors, walls, and ceiling are made out of, and you can tell if a creature has been in this room within the last hour; however, the type and quantity are unknown to you.)
You also gain advantage on Intelligence (Investigation) checks to find secret doors, levers, or traps and you also gain advantage on Wisdom (Perception) checks to spot hidden obstacles as well. You also gain advantage on Intelligence (Arcana) checks to discern if there are any magic secrets within the room. You also gain advantage on Wisdom (Perception) checks to spot hidden obstacles as well. 

While under the effects of "Trap Inspection" you have advantage on saving throws against any effect that would tamper with your memory.
