Nagaji were originally humans who transformed themselves through ancient rituals. Most nagaji were corrupted into monsters by those rites, but some nagaji instead became a new people who mix characteristics of humans and snakes.
Blessed with resistance to poisonous effects by the rituals that created them, each of these nagaji manifests their serpentine heritage in a variety of ways: a forked tongue, snake eyes, a snakelike nose, or some other ophidian characteristic. However a nagaji looks, they have the power to pursue great good or evil.
Your nagaji character has the following traits.
Creature type. You are a Humanoid.
Health. Your health increases by 8.
Size. Your size is Medium and you stand between 150 centimeters and 180 centimeters tall.
Speed. Your base walking speed is 5 meters.
Age. Nagaji mature at the same rate as humans. On average, they live about 80 to 120 years.
Darkvision. Your advanced artificially-designed eyes grant you superior vision in dark and dim conditions. You can see in dim light within 10 meters of you as if it were bright light, and in darkness as if it were dim light. You can’t discern color in darkness, only shades of gray.
Parseltongue. You can communicate in a limited manner with snakes. They can understand the meaning of your words, though you have no special ability to understand them in return. You have advantage on all Charisma checks you make to influence them.
Shed Skin. Once on your turn, you can shed your skin to free yourself from a grapple, shackles, or other restraints. Once you use this trait, you must finish a short or long rest before you can use it again.
If you spend 1 minute eating your shed skin, you regain health equal to your Aptitude Bonus + your Constitution.
Poison Resistance. You have advantage on saving throws against poison, and you have resistance against poison damage.
Serpentine Magic. You have inherited the innate spellcasting ability of your ancestors. You know the charm or the poison spray cantrip. When you reach 3rd level, you know the hypnotize spell and 1 spell from the Poison theme and can cast one without expending mana. You regain the ability to cast one of these spells with this trait when you finish a long rest. If you do not have a spellcasting ability, choose Intelligence, Wisdom, or Charisma as your spellcasting ability for these spells.
At 5th level you regain the ability to cast one of these spells with this trait when you finish a short or long rest. At 13th level your spell is augmented to 2 mana.
If you have mana, you can augment your spell by expending mana, up to your mana limit.
