Your Wisdom score increases by 2 and your Dexterity score increases by 1.

When taking a short rest, you can choose to cocoon yourself within a hard shell. For the duration of the rest you cannot perform any other actions, but can spend one additional hit dice for free. This must be the smallest hit dice you have available.

You have Natural Weapons capable of dealing 1d6+ your Dexterity modifier. These can take many forms and the type of damage they deal can be chosen at the end of any short rest (Slashing, Bludgeoning, Piercing). At 3rd level your natural weapons deal 1d8+ your Dexterity modifier. At 5th level they become magical weapons and you can apply one positive adaptation trait permanently.
