Stage 1 Boon: Aberrant Mutation

Aberrant Horror Stage 1 Boon

Your body can twist and reshape itself as you will it, changing body parts into dangerous or useful tools and regenerating after taking damage. These abilities are represented by Aberrant Mutations. You can manifest an Aberrant Mutation listed below a number of times equal to 4 plus your Proficiency Bonus.

Each of these Aberrant Mutations last for 1 minute, and you can end them early by spending a Bonus Action to remove them or take on a different mutation. If you choose another Aberrant Mutation, you must spend another use of this feature.

You regain all uses of this ability when you finish a Short or Long Rest.

Chitinous Shell. As a Bonus Action, you grow a hard, crustacean-like shell. While this mutation is active and are not wearing heavy armor, your Armor Class increases by 2. While you maintain this shell, your Speed is reduced by 10 feet.

Eldritch Limbs. As a Bonus Action, you transform one or both of your arms into thick muscle, scything claws, or sharpened bone. When you use the Attack action, you can replace one or more attacks with melee attacks made with your eldritch limb. You are considered proficient with this attack, and it uses either Strength or Dexterity (your choice). On a hit, the attack deals 1d8 damage (either Bludgeoning, Piercing, or Slashing, chosen each time you manifest the mutation). As a Bonus Action, you can make a melee attack with your eldritch limb. Your eldritch limbs cannot hold weapons, shields, or other items. They are not considered weapons or Unarmed Strikes.

Slimy Form. As a Bonus Action, you cover yourself in a slippery slime. You have Advantage on ability checks to escape a grapple, and you can use the Dash action as a Bonus Action. You also gain Resistance to Acid, Fire, and Cold damage while in this form.
