Basilisk-blooded carry the blood of basilisk-kind.
Swimming speed: Lizardfolk have a swimming speed of 30 feet.
Bite: Lizardfolk's fanged maw is a natural weapon, which they can use to make unarmed strikes. If they hit with it, they deal piercing damage equal to 1d6 + Strength modifier, instead of the bludgeoning damage normal for an unarmed strike.
Hold breath: Lizardfolk can hold their breath for up to 15 minutes at a time.
Hunter's lore: Lizardfolk gain proficiency with two of the following skills of their choice: Animal Handling, Nature, Perception, Stealth, and Survival.
Hungry jaws: In battle, Lizardfolk can throw themselves into a vicious feeding frenzy. As a bonus action, they can make a special attack with their bite. If the attack hits, it deals its normal damage, and they gain temporary hit points (minimum of 1) equal to their Constitution modifier, and they can't use this trait again until they finish a short or long rest.
Petrifying glare: As an action once per long rest, Basilisk-blooded can force a creature within 30 feet to make a Constitution saving throw (DC = 8 + Constitution modifier + proficiency bonus). On a failed save, it is restrained until the end of the Basilisk-blooded's next turn. The creature is not petrified, just slowed as its limbs stiffen. The creature is immune if blind.
Venom resilience: Basilisk-blooded have advantage on saving throws against poison and resistance to poison damage.
