Lizardfolk reach maturity at the same rate as their terrestrial kin, reaching adulthood around age 14, but they live much longer: up to 400 years.

Most lizardfolk are neutral. They see the world as a place of predators and prey, where life and death are natural processes. They wish only to survive, and prefer to leave other creatures to their own devices.

Lizardfolk are a little bulkier and taller than humans, and their colorful frills make them appear even larger. Your size is Medium.

Your base walking speed is 30 feet, and you have a swimming speed of 30 feet.

Your long tail is a natural weapon, which you can use to make unarmed strikes. If you hit with it, you deal bludgeoning damage equal to 1d6 + your Strength modifier, instead of the damage normal for an unarmed strike.

If you take the attack action and make an attack with a weapon, you can attack with your tail as a bonus action, though you do not add your Strength modifier to the bonus attack's damage unless you have the Two-Weapon Fighting style or are a monk. 

You can hold your breath for up to 15 minutes at a time.

You have tough, scaly skin. When you aren’t wearing armor, your AC is 13 + your Dexterity modifier. You can use your natural armor to determine your AC if the armor you wear would leave you with a lower AC. A shield’s benefits apply as normal while you use your natural armor.

You can speak, read, and write Common and Draconic.
