The Rains of Castermere

Creatures that can hear you play this haunting melody must make a Wisdom saving throw. A target automatically succeeds on this saving throw if it is a magic user, or is sworn to House Lannister. On a failed save, a target is affected by this spell. Until the spell ends, the target becomes terrified, and will obey the caster’s commands.

A target won’t do anything to directly endanger itself, but instead will give coin, information, gear, and sometimes assistance in battle. The spell wears off if another song is played, or after an hour.
