Snake Charmer

Jurin-Kaa are described as being otherworldly snake people, and some of them can actually turn themselves into snakes. You gain the following benefits:

• Increase your Constitution or Charisma modifier by 1, to a maximum of 20.
• As an action, you can transform yourself into a snake for 1 hour. While transformed, you gain the following benefits:
  • Your size becomes Huge, but you can still fit into spaces that a Small creature can.
  • You have a climbing speed, swimming speed, and crawling speed equal to your walking speed, and you cannot be knocked prone.
  • You have blindsight out to a range of 10 feet.
  • You gain temporary hit points equal to five times your level.
  • You have two natural attacks, that each use your choice of your Strength or Dexterity modifier for attack rolls and damage rolls. You can make a bite attack, that on a hit, deals 1d6 plus your chosen modifier in piercing damage, and an additional 1d6 poison damage. You can make a tail attack, that on a hit, deals 1d6 plus your chosen modifier in bludgeoning damage. A creature hit with the tail attack is then grappled (escape DC equal to 8 + your chosen modifier + your proficiency bonus), and takes an additional 1d6 bludgeoning damage at the start of each of its turns. You then cannot use your tail attack until the creature is no longer grappled, but you have advantage on bite attacks you make against the grappled creature. Attack rolls you make in this form have a natural reach of 10 feet.
  • As an action, you can attempt to hypnotize a creature within 30 feet of you that can see you. The creature must succeed on a Charisma saving throw (save DC equal to 8 + your Charisma modifier + your proficiency bonus), or become charmed by you for 1 minute. While charmed in this way, the creature is also slothful. You can only have one creature charmed by you at a time using this feature.
  • Your gear melds into you, and is still in effect for you. You can wield any object that can fit in one or two hands, using your tail.

Once you use this feature, you can't use it again until you finish a long rest.

(Slothful - A creature with the slothful condition can make a maximum of one attack on its turns, cannot take bonus actions, reactions, or legendary actions, and cannot cast spells or use the properties of magic items.)
