• Sturdy Arms: By virtue of their superior strength, Alperns can wield greatswords, mauls or greataxes with one hand; held with one hand, these weapons deal 1d10 damage.
• Mighty Limbs: This race manifests traits inherited from the beasts to which they are so close; therefore, you are Proficient in Athletics.
• Reckoning of Betrayal: The curse imposed by the Trudens exacts a harsh toll on the Alperns during the lunar cycle; the rays of the Full Moon, and of the Birthmoon of each individual Alpern, alter their appearance with animal traits, while maintaining a humanoid form. Depending on the Atavistic Beast , an animal extinct during the first two ages, you choose at character creation, you can develop a fur or plumage, a carnivorous dentition or rapacious claws. The shapeshifting grants a particular feature and persists throughout the entire Lunar Phase, after which you regain your usual appearance; if the Birthmoon corresponds to the Full Moon, the characters also gain the Beast Moon feature listed for their Atavistic Beast.

When characters take on bestial traits, they have Disadvantage on Charisma checks (except Intimidation).
