Additional Yuan-Ti Traits
These traits can be found on page 98 of Volo's Guide to Monsters. These are additional traits that your Dungeon Master may apply to your Yuan-Ti Pureblood.
 * Chameleon Skin - You have advantage on Dexterity (Stealth) checks made to hide.
 * Shapechanger - You can use your action to polymorph into either a Medium giant poisonous snake or a Large constrictor snake. You may use an action to transform back into your normal form. You gain the statistics of the respective creature you become, except for the size change noted and you retain your previous Hit Points. Any equipment you are carrying melds with your new form and becomes unusable while in your transformed state. If you die while transformed this way, you do not change back and your equipment sheds from you on the square you died at or within 5 feet of you.
 * Shed Skin - While you are grappled, you can use a bonus action to shed your skin in order to free yourself from a grapple, manacles, or other restraints. If you spend 1 minute eating your shed skin, you regain Hit Points equal to half of your Hit Point maximum. You can only use this ability once per long rest.
