Rodent Embraced

You have completely mastered the rat within and learned tricks to make your lycanthropy an even greater asset in combat. You can transform one additional time without suffering a level of fatigue. When you choose to tame the beast in an involuntary transformation, roll 1d8; you gain control over that many hours. While you are transformed, you gain the following features.

Full Moon Defense. You gain immunity against slashing, bludgeoning, and piercing damage from weapons that are not magical or silvered.

Nose for Opportunity. When an ally strikes a creature you can see with a melee attack, you can use your reaction to move up to your Speed, ending your move adjacent to that creature and making a melee weapon attack against it. If the creature is bloodied and the attack hits, you score a critical hit. Once you have used this feature, you cannot use it again until you finish a short or long rest .

Wererat Trickery. When you reduce a creature to 0 hit points with a bite attack, you can use your reaction to take the Disengage, Dodge, or Hide action.
