Your Charisma score increases by 2.

Selkies age at the same rate as half elves, living up to 150 years.

Selkies tend towards good alignments.

Selkies vary in size, but average between five and six feet tall, depending on your subrace. Your size is medium.

In humanoid form your base speed is 30ft on land and 20ft when swimming, in seal form 20ft on land and 45ft swim speed.

You can speak Common and Sylvan.

Coming from cold waters, you have resistance to cold damage. You also do not feel the effects of cold weather.

Selkies can shed or don their seal skin to change between humanoid and aquatic form. It takes one minute to switch between forms. In order to return to seal form you must have your skin - without it, you are stuck in humanoid form. You cannot wear armor under your skin but small trinkets like necklaces, earrings, bracelets, etc. can be kept on. You only benefit from the items that you are wearing on your body while in seal form. Your humanoid physical stats are replaced by specific stats for your seal form. Your skin takes up 2 square feet of space when folded.

Due to the nature of your shapeshifting you are immune to spells which would change your form (excluding invisibility). You are still susceptible to illusions.

Your creature type is Fey. If you are being sought by magical means you appear as fey, not humanoid.
