When you set a mine, you can link it to a remote detonator, allowing any creature holding the detonator to trigger the mine as an Interact action.
Typically, a detonator’s range is limited to 1,000 feet, but a mine connected to a detonator via a computer network can be detonated from essentially any distance.
