Merfolk

Amphibious. The merfolk can breathe air and water.

Coral Spear. _Melee Weapon Attack:_ +3 to hit, reach 5 ft., one target. _Hit:_ 4 (1d6+1) piercing damage.

Sharpened Shell. _Ranged Weapon Attack:_ +3 to hit, range 20/60 ft., one target. _Hit:_ 3 (1d4+1) slashing damage.

Nimble Rush. The merfolk takes the Dash or Disengage action.

Coral Scrape. When a creature the merfolk can see hits it with a melee attack while within 5 feet of it, the merfolk can twist its body to scrape the attacker's arm or similar attacking appendage across the rough coral of its armor. The attacker must succeed on a DC 11 DEX save or have disadvantage on the next attack roll it makes before the end of its next turn, as its attacking appendage hurts from the abrasion.
