Serpentine Sorcery

You discover an ability that few other Yuan-Ti have, tracing back to the old days of an ancient Yuan-Ti empire. You gain the following benefits:

• Increase your Charisma score by 1, to a maximum of 20.
• When you are hit by an attack that deals poison damage, you are instead healed by half the damage rounded up.
• As an action you can attempt to hypnotize a creature. The creature must make a charisma saving throw, DC 8 + your proficiency bonus + your charisma modifier. On a failure, the creature is charmed, and can repeat the saving throw at the end of each of its turns. If the creature fails the original saving throw by 5 or more, they cannot repeat the save. You can only hypnotize 1 creature at a time, and attempting to hypnotize another will free the first creature. The condition ends after 1 minute or if the creature takes damage.
