One Last Tweak

You can't seem to resist toying with mechanical contraptions.  When interacting with any non-trivial lock or mechanical device, you must make a successful DC 15 Wisdom(Investigation) check or become afflicted with the condition of the Enthrall spell for 1 minute.  After 1 minute has passed, you can automatically succeed at opening the lock or solving the device, however your efforts have left it more complicated, and all subsequent efforts to interact with it must be made at +1 DC.  If you succeed at your Investigation check, any checks made against the object are made with Advantage.
