Electromagnetic Whiskers

You've honed your whiskers' sensitivity to the degree that you can sense the movement of the weak electric fields emitted by potential enemies. You gain electromagnetic sense as an imprecise sense out to 15 feet. Electromagnetic sense allows you to detect nearby living and technological creatures, but you might have to use the Seek action to find an undetected creature in an environment with too much electromagnetic radiation, such as inside the engine room of a spaceship or near a powerful source of radio waves.
