Plight of Palomar

This ebony black wooden ring is dotted with thorns on the outside.
Once per day, you may cast the following spells without expending a spell slot or material component:
Thorn Whip (Cantrip)
Speak with Animals (1st level)
Spike Growth (2nd level)
Curse: This ring represents the pain and suffering of it's creator. Whenever this ring is used to cast a spell, the wearer suffers piercing damage equal to the level of the spell multiplied by 5 (minimum of 5.)
Factus Formis is currently attuned to the ring.
Archmagi Kistarin Yvris has removed the curse from the item, allowing the spells to be cast without damage.
