Your Charisma score increases by 2 and two other skills increase by 1

You have a Darkvision of 60 ft, you can see in dim light as if it were well lit, and darkness as if it were dim light. Your darkvision works in shades of gray.

Once per day, you may touch a creature and gain knowledge of how to speak one language they know. The knowledge of how to speak this language fades from your mind after 4 hours

You are vulnerable to psychic damage.

You know Common, Elvish, and one other language of your choice.

Once per day, as an action, when you touch a creature, you gain knowledge of what that creature is and also the ability to replicate one of it's racial features. This ability cannot let you increase or decrease your ability scores or gain spells. Upon replicating a trait of a race, your body changes slightly to accomodate this change. 

Examples:
Half-Orc "Brutal Critical": You grow light tusks from your bottom row of teeth.
Aaracokra "Flight": You sprout wings, your armor needs to have room for this effect to take place
Gnome "Gnome Cunning": Your eyes become slightly larger.
Changeling "Shapechanger": Your skin becomes pale white until you decide otherwise
Grung "Poisonous Skin": You begin to secrete a sweat-like substance that is poisonous to the touch

When you gain a physical trait from changing, it might not always be the same for the same trait. It may have multiple ways of manifesting and it's up to you or your dm in how it manifests.

You can only use this trait once per day, but you keep the new trait you've gained until the next time you use this trait. Upon learning a new trait, you lose your old one and any physical effects it brought.
