Sharkskin Suit

Armor (light), rare

This deep blue armor is covered with tiny razorsharp scales and embedded with petrified shark’s teeth. The scales and teeth lie smooth and flat most of the time, but any creature attempting a Strength (Athletics) check to grapple or shove you takes 1 piercing damage, and a creature beginning its turn grappling you takes 1d3 piercing damage (1d6 piercing damage if you are swallowed whole).

Whenever you succeed on a Strength (Athletics) check to shove or grapple a target, you also deal 1d3 piercing damage to your target. While wearing a sharkskin suit, you gain a swim speed equivalent to your normal speed and can sense the presence and location of creatures who have bled in the same body of water and track them to their location with a Wisdom (Survival) check. So long as the target creature is bleeding and in the water you have advantage on this skill check.
