Elven Night

You half the time of the next rest (does not stack with other effects that reduce the rest time) for up to five(+2 per level above 4th) creatures that you can see plus yourself. As you sing an ancient elven song the diamond disappears above you creating what looks like a beautiful starry night sky above your head. Every creature that hears the song must make a wisdom saving throw or be charmed for the duration of the song (the max number of creatures charmed is determined by the damage(like the mage spell sleep)), does not work when already in combat.
