Seal Skin

Wondrous Item Rare (this item requires attunement)

The seal skin of a selkie is their most precious item, as it is what allows them to swim across the seas, and those that lose it become depressed and resentful.   This item can only be attuned by the Selkie that owns it. While attuned, the skin provides different benefits, depending if the selkie is wearing it or simply in close proximity (at least 15 feet) to it. The latter benefits are constantly active.   Warm Blubber. When simply in close proximity to this item, you can survive in the Extreme Cold and Extreme Pressure with no harmful effects. While wearing this item, you become resistant to Cold Damage.   Natural Armor. While wearing this, your thick blubbery skin provides you protection. When you aren't wearing armor, your AC is 13 + your Dexterity modifier. You can use your natural armor to determine your AC if the armor you wear would leave you with a lower AC. A shield's benefits apply as normal while you use your natural armor.   Aquatic. While in close proximity to this item, you can hold your breath for up to 3 hours and can rely simple messages to aquatic animals, although you cannot understand them. While wearing the skin, you gain a swim speed of 60ft, however your normal walking speed and climbing speed (if you have one) are halved.
