Choose two of the following skills:

Insight, Nature, Persuasion, or Survival. You have proficiency in those skills.

When another creature within 10 feet of you damages you with a melee attack roll. you can take a Reaction to release a barbed steam that attaches to the creature. The creature immediately takes 1d4 Piercing damage and, each time it takes Bludgeoning damage while a stem is attached to it, it takes an extra 1d4 Piercing damage per attached stem.

If the creature takes Fire damage, all stems on it fall off. A creature can use its action to make a Wisdom (Medicine) check (DC 8 plus your Constitution modifier and Proficiency Bonus), removing one stem from itself or another creature within its reach on a success.

You can take this Reaction a number of times equal to your Proficiency Bonus, and you regain all expended uses when you finish a Long Rest.

Photoabsorption. When you take Radiant damage, you can take a Reaction to halve the Radiant damage against you. When you do so, you gain Temporary Hit Points equal to the damage reduced, to a maximum equal to your Constitution modifier plus your Proficiency Bonus (minimum of 2 Temporary Hit Points).

Forgoing food doesn't give you levels of Exhaustion if you spend at least 6 hours in direct sun-light, or 12 hours in indirect sunlight, that day.

Your skin is covered in long, nee-dle-like spines. Whenever you end your turn grappling or Grappled by another creature, you can attempt to pierce that creature with your spines. Make a Constitution check (DC equals the creature's AC). On a success, the creature takes Piercing damage. To determine this damage, roll a number of d4s equal to your Proficiency Bonus and add them together.
