Describe or name a creature that is familiar to you. You sense the direction to the creature's location, as long as that creature is within 1,000 feet of you. If the creature is moving, you know the direction of its movement.
The spell can locate a specific creature known to you, or the nearest creature of a specific kind (such as a human or a unicorn), so long as you have seen such a creature up close - within 30 feet - at least once. If the creature you described or named is in a different form, such as being under the effects of a polymorph spell, this spell doesn't locate the creature.
This spell can't locate a creature if running water at least 10 feet wide blocks a direct path between you and the creature.
When you cast this spell, choose one humanoid within range that can see and hear you, and that can understand you. The creature must succeed on a Wisdom saving throw or become charmed by you for the duration. While the creature is charmed in this way, it undertakes to perform any services or activities you ask of it in a friendly manner, to the best of its ability.
You can set the creature new tasks when a previous task is completed, or if you decide to end its current task. If the service or activity might cause harm to the creature, or if it conflicts with the creature's normal activities and desires, the creature can make another Wisdom saving throw to try to end the effect. This save is made with advantage if you or your companions are fighting the creature. If the activity would result in certain death for the creature, the spell ends.
When the spell ends, the creature knows it was charmed by you.
