Amulet of the Chaos Warrior

When you finish a long rest while wearing this amulet, you gain 1d4 × 10 temporary hit points.

While you have these temporary hit points you gain the following benefits:

• You have advantage on attack rolls that you make with simple and martial weapons.
• You have advantage on Strength, Constitution, and Charisma saving throws.
• When you hit a target with a weapon attack, the target takes 2d8 damage. Choose one of the damage dice. The number rolled on that die determines the attack’s damage type, as shown below.

  d8	Damage Type
  1	Acid
  2	Cold
  3	Fire
  4	Force
  5	Lightning
  6	Poison
  7	Psychic
  8	Thunder

  If you roll the same number on both d8s, chaotic energy leaps from the target to a different creature of your choice within 30 feet of it. Make a ranged spell attack roll, using your spell attack modifier (Barbarians use Charisma, Fighters use Intelligence, Monks use Wisdom, and Rogues use Intelligence) against the new target, and make a new damage roll, which could cause chaotic energy to leap again.

Notes: Disclaimer: the idea behind this item is that I randomly selected an item (an amulet), along with two spells (Tenser's Transformation and Chaos Bolt). So, there is no rhyme or reason to this magic item., Damage, Buff, Combat
