Some bullywugs are born with the ability to weave magic into their songs. These rare specimens are raised in protected enclaves where they are taught to use their magic to both heal and harm. As demonstrated in Danger at Dunwater, they are among the most pompous of bullywugs.

• Up to three times per long rest you can sing a song of marshy doom. Each chosen creature within 30 feet of you that can hear the song must make a DC 12 Wisdom saving throw, taking 2d8 psychic damage on a failed save, or half as much damage on a successful one. A creature that fails this saving throw also has disadvantage on Constitution saving throws until the end of its next turn.  Wisdom is your spellcasting ability for this.
• Once per long rest, you can sing an ode to an elder froghemoth. Each ally within 30 feet of you that can hear and understand the song gains 10 temporary hit points.
