Clavdia

Keen Senses. Clavdia has advantage on Wisdom (Perception) checks that rely on hearing or smell.

Reckless. At the start of its turn, Clavdia can gain advantage on all melee weapon attack rolls during that turn, but attack rolls against her have advantage until the start of her next turn.

Danger Sense. Clavdia gains an uncanny sense of when things aren’t as they should be, giving her an edge when she dodge perils. She has Advantage on Dexterity saving throws unless she has the Incapacitated condition.

Volatile Serum.  She have an implanted series of syringes and reservoirs that hold alchemical serums and deploy them into your  body. When you enter your Rage, choose one of your serums to inject and gain its benefits. The chosen serum lasts for the duration of your Rage,  or until you choose a new serum as a Bonus Action. You have the following serum options.

Ferocity. This serum throws you into an energized  frenzy. You ignore Difficult Terrain, and when you hit with a Melee weapon or Unarmed Strike, you can activate the Cleave mastery property in addition to a different mastery property you're using.
Monstrosity. The serum expands your body to monstrous proportions and can change your appearance  in cosmetic ways, such as by altering facial features, skin  tone, and hair length or color. Your reach increases by 5 feet, and once per turn when you miss with an attack  roll that relies on Strength, you can add your Rage Damage bonus to the total, potentially causing the attack  to hit. If you are smaller than Large, you become Large,  along with anything you are wearing or carrying. If there isn’t enough room to accommodate the size change, your size doesn't change.
Reconstruction. The serum dulls pain and forces  wounds to rapidly knit. Upon activation and at the  start of each of your turns, you can expend and roll a  Hit Point Die. You regain a number of Hit Points equal  to the number rolled plus your Constitution modifier  (minimum of 1 Hit Point). You gain any excess beyond  your Hit Point maximum as Temporary Hit Points.  If you take Acid or Fire damage, this serum doesn't  function at the start of your next turn.
