Tale of Dread

This spell was created by an ancient night hag named Auntie Penny Hog. She would posed as a midwife, and care giver.  When people would seek her advice or care she would take the opportunity to use this spell on children to subtly control the towns people. She would "cure the children" of their aliments when the parents did what she asked of them, praising the gods for their intervention.  She would sometimes host a story time in the town square, and all those children who listened would become ill, and she would be revitalized.  Eventually the town priest figured it out, and sought retribution for the pain she had been inflicting on the towns children.  The spell was recorded in the church records, and it didn't stay secret for long. 

The caster plays a powerful and dramatic song or tells tale  about a doom and tragedy.  Any Creature within a 15ft radius must make a Wisdom saving throw. On a failed save the spell does 1d4+1 damage to the maximum hit points to all of those creatures. Also, the caster gains 1 temporary hit point per target effected. This effect lasts until the targets finish a long rest.
