As you move you passively cause harmless tremors in the ground. This causes loose debris to rumble and anything not secure to possible be jostled. Any trap within 5ft of you that is not magical and relies on movement is triggered. Not only do you cause items to reverberate you can also sense the reverberation you cause giving yourself 5ft of tremor sense.  This also imposes disadvantage to stealth while moving on the ground. Grants 5ft extra movement.
