Your Constitution score increases by 2.

Dry Bones may be any age, though they are usually made from the remains of an adult koopa troopa. You might have died young or you may have succumbed to old age.

Dry bones tend toward lawful evil because they follow the commands of King Koopa. Some might come back to life for other purposes.

Your lack of flesh makes you much thinner than the average koopa troopa. Your size is Medium.

Your base walking speed is 30 feet.

You can speak, read, and write Common and Koopa. Koopa is spoken in a mix of clicks, croaks, and chirps.

You gain a +1 bonus to your AC due to your bony shell.

Your bones are considered melee weapons with which only you are proficient, and which have the Thrown property. The damage dealt by one of your bones is equal to the total rolled on your Hit Die + your Constitution modifier. Your Strength modifier applies as normal.

Once on your turn as bonus action you can spend a Hit Die to remove a bone from your body. For every bone you remove once you have no more Hit Die remaining, roll a Hit Die. You take necrotic damage equal to the total on the die.

Your type is Undead instead of Humanoid. You don't require air, food, drink, or sleep. You are immune to poison and disease, and you cannot become exhausted.

You are vulnerable to bludgeoning damage. If you are brought down to 0 hit points, your body crumbles and you die instantly.

If you were killed by nonmagical bludgeoning, piercing, or slashing damage, you reform 1 minute later in the closest unoccupied space to where you died with all the benefits of a long rest.

If you were killed by any other means, you must wait 24 hours before reforming.
