Carulia's Harmonious Tether

Created by Carulia to travel through the Labyrinth, the caster may touch one willing creature they wish to be tethered with for the duration of this spell, binding them by an invisible string only visible by those affected. For the duration, the two tethered together cannot be forcibly separated by more than 30 feet, and as a bonus action one of those tethered can touch their end of the string to sense the location of the creature tethered to them. Once while this spell is active, one of those tethered can use an action to teleport the other creature tethered to them their side, as long as they are within 120 feet of them. This is to ensure those are never separated from the ones they love.
