Disciple of Dagon's Armor
Medium Armor (Half Plate), Uncommon (requires attunement)
The armor is made of black, molded bone plates and is warm to the touch. Because it is made of bone, it is lighter than standard Half Plate (20 lbs).
Once attuned, this armor grants you a swimming speed equal to your walking speed and resistance to Cold damage, and does not impose disadvantage on Stealth rolls.
