Watcher's Ward

You touch a willing creature other than you and mark it with a faintly glowing symbol that lasts for the duration. The symbol also disappears if you or the marked creature dismiss it as an action, or if you cast it again. You choose the spell's appearance, as well as if it's visible to others. While marked the creature's on the same plane of existence as you, you know the direction to it and whether it has at least 1 hit point. Once during the spell's when you cast a spell with a range of touch, you can target the creature even if it isn't within your reach. The creature must be on the same plane as you, after which the spell ends.
