Young tortles crawl for a few weeks after birth before learning to walk on two legs. They reach adulthood by the age of 15 and live an average of 50 years.

Tortles tend to lead orderly, ritualistic lives. They develop customs and routines, becoming more set in their ways as they age. Most are lawful good. A few can be selfish and greedy, tending more toward evil, but it’s unusual for a tortle to shuck off order in favor of chaos.

Tortle adults stand 5 to 6 feet tall and average 450 pounds. Their shells account for roughly one-third of their weight. Your size is Medium.

Your base walking speed is 25 feet.

Your claws are natural weapons, which you can use to make unarmed strikes. If you hit with them, you deal slashing damage equal to 1d4 + your Strength modifier, instead of the bludgeoning damage normal for an unarmed strike.

You have a swim speed of 40 ft.

These Tortles are adapted to the open sea. A such they are amphibious, able to remain away from land indefinitely. 

Due to your shell and the shape of your body, you are ill-suited to wearing armor. Your shell provides ample protection, however; it gives you a base AC of 17 (your Dexterity modifier doesn’t affect this number). You gain no benefit from wearing armor, but if you are using a shield, you can apply the shield’s bonus as normal.

When you use your breath weapon, each creature in the area of exhalation must make a saving throw. The DC for this saving throws equals 8+ your Constitution modifier + your proficiency bonus, taking 2d6 fire damage on a failed save, and half a much damage on a successful one. The damage increases to 3d6 at 6th level, 4d6 at 11th level, and 5d6 at 16th level. 

After you use your breath weapon, you can't use it again until you complete a short or long rest. 

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