Serpentine Aspect

You manifest scales and fangs reminiscent of your more ophidian yuan-ti kin. You gain the following benefits:

• Increase your Dexterity, Constitution, or Charisma score by 1, to a maximum of 20.
• Your skin manifests a thin sheen of iridescent snake scales. While you aren’t wearing armor, you can calculate your AC as 13 + your Dexterity modifier. You can use a shield and still gain this benefit.
• You grow retractable fangs and gain the ability to unhinge your jaw. Extending or retracting the fangs and unhinging you jaw requires no action. The fangs are natural weapons, which you can use to make unarmed strikes. If you hit with them, you deal poison damage equal to 1d6 + your strength modifier instead of the normal bludgeoning damage for an unarmed strike. No more than one such venomous strike may be made per round.
