Trap Mechanist

You can spend ten minutes studying a disabled trap to learn about its inner workings, including what triggers it and how to disable it. 

While moving at a normal speed, you can concentrate to be on the lookout for traps of the same design as those you've already studied. While concentrating, you automatically detect those traps, and can use an action to disable them, provided you have the appropriate tools to do so. 

Additionally, you can make a Wisdom (Perception) check at the start of new area (as determined by your DM) to be on the lookout for inconsistencies in the area's design and layout. You can choose to use the result of this check instead of your Passive Perception for the purpose of detecting traps.
