Binding Oath

You bind a creature's soul to an oath it speaks. A willing creature you remain touching while you are casting this spell may speak an oath in a language you understand. The oath must begin with the phrase "I swear...".

For the duration, if the touched creature breaks their oath, they gain one level of exhaustion. When the creature breaks its oath or completes its sworn task(s), the spell ends. You feel if the oath is broken or dispelled, and can also sense the location of the creature at the moment the oath is broken.
