You have resistance to poison damage and advantage on saving throws against being poisoned.

You can choose to gain proficiency in one of the following skills: Nature, Deception, or Insight.

You do not age past maturity, and magic cannot age you. Your body retains a lifelike vitality even after death. When you drop to 0 hit points but are not killed outright, you can make a Charisma saving throw (DC = 5 + the damage taken). On a success, you drop to 1 hit point instead. You can use this feature once per long rest.

You have advantage on Stealth checks when moving through natural terrain or dim light.

You can cast Detect Thoughts once per long rest, using Charisma as your spellcasting ability.

As an unarmed strike, you can bite a creature within 5 feet. On a hit, the target takes piercing damage equal to 1d4 + your Strength modifier and must succeed on a Constitution saving throw (DC = 8 + your proficiency bonus + your Charisma modifier) or take 1d6 poison damage.
