When you put this sword on a flat surface or the palm of your hand, it slowly rotates to indicate North with its blade. You have a +1 bonus to attack and damage rolls made with this magic weapon.
Once per long rest, you can put the blade on a flat surface or the palm of your hand and say the name of a specific object or creature that you have already seen or are familiar with. If it is within 1000ft of you, the blade will rotate and point toward your target. The blade keeps pointing toward the target for 10 minutes even as you move, as long as the target stays within range, not knowing the actual distance of the target. If you drop the blade or use it to fight, the effect ends.
Proficiency with a shortsword allows you to add your proficiency bonus to the attack roll for any attack you make with it.
