Carcharion

Bite. Your jaws are a natural weapon, which you can use to make unarmed strikes. If you hit with them, you deal piercing damage equal to 1d6 + your Strength modifier, instead of the bludgeoning damage normal for an unarmed strike.   Bloodied Fury. If you make an attack against a target without their full hit points, and you can smell their blood , you can unleash a fury from the scent. This allows you to add an additional 1d10 to any melee attack's damage. After you use your bloodied fury, you can't use it again until you complete a long rest.   Darkvision. Accustomed to the depths of the ocean, you have superior vision in dark and dim conditions. You can see in dim light within 60 feet of you as if it were bright light, and in darkness as it if were dim light. You can't discern color in darkness, only shades of grey.   Natural Predator. If a creature or target attacks you, you can use a reaction and attack back with your Bite. You can do this a number of times equal to your Proficiency Modifier, and then cannot use it again until you complete a long rest.   Slippery Skin. Just like sharks, Carcharions skin is naturally lubricated and thus creatures have disdavantage when trying to Grapple you when you're in water.   Waterborne. Your base walking speed is 25 feet due to not being adapted to land, but you have a swim speed of 35 feet. While in water you gain advantage on Melee Attacks.   Languages. You can speak, read and write Common and Aquan.   Subrace. Carcharions come in several different forms depending on the depth of their hatching. There are three main subraces: hammerhead, great white, and reef.
