Amulet of Storm-Breaking Life

Should the wearer fail all death saves or take fatal damage while he/she is outside and has a clear view of the sky, the Amulet will trigger. For one round, any creature that comes within 10 feet of the wearer must make a Dexterity saving roll, or suffer 5d10 Lightning damage, or half as much on a successful save. During this round, a cylindrical cloud starts forming and growing up to 10 feet tall with a radius of 10 feet. At the end of the wearer's next turn, the wearer is struck by lightning from the cloud and is brought back to half of their max Hit Points and cured of all conditions and effects. They also regain spell slot levels equal to their level (i.e. a 5th level character regains 5 levels worth of spell slots) excluding 8th or 9th level slots. For the next three rounds, the wearer has +2d6 lightning damage on all attacks or spells that cause damage directly (i.e. Magic Missile). 

The Amulet is completely broken after one use. It cannot be repaired, sold, reused, or scrapped for materials. If the Amulet is attacked directly, it has 14 hit points until it breaks and, if it has a clear view of the sky, triggers. all of the previous effects occur, except focused solely on the Amulet. When the lightning strikes, it deals 5d10 Lightning damage to any creature within 15 feet of it and does not provide any restoration or damage increase.
