Espionage

Choose one creature within range. For up to a minute, you can listen in on what this creature says. While this spell is cast, you understand any language spoken by that creature, even if you don't speak that language. Once the spell ends, the creature is alerted that they had been listened in on, but they know not who cast it, nor at what point the spell was cast.

At Higher Levels: When you cast this spell using certain higher-level Spell Slots, you can listen in on additional creatures: 2 creatures with a 3rd level slot, and 3 creatures with a 5th level slot.
