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.

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 30 feet.

You can hold your breath for up to 1 hour at a time. Tortles aren't natural swimmers, but they can remain underwater for some time before needing to come up for air.

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.

You can withdraw into your shell as an action. Until you emerge, you gain a +4 bonus to AC, and you have advantage on Strength and Constitution saving throws. While in your shell, you are prone, your speed is 0 and can't increase, you have disadvantage on Dexterity saving throws, you can't take reactions, and the only action you can take is a bonus action to emerge from your shell.

You gain the Thaumaturgy cantrip. It does not count toward your maximum number of cantrips known.

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