Might of the Dragon Turtle

You have developed traits similar to that of a Dragon Turtle, granting you the following benefits:

• Increase your Strength or Constitution by 1, to a maximum of 20.
• You have an AC of 18 while you aren't wearing armor.
• You gain a swimming speed equal to your walking speed.
• You gain resistance to fire damage.
• You gain fluency in Aquan and Draconic.
• You gain the ability to breathe air and water.
• As an action, you can exhale scalding steam in a 20-foot cone. Each creature in that area must make a Constitution saving throw (DC 8 + your proficiency bonus + your Constitution modifier), taking 4d6 fire damage on a failed save, or half as much damage on a successful one. The damage increase to 6d6 damage when you reach 17th level. Being underwater doesn’t grant resistance against this damage. You can use this feature a number of times equal to your proficiency bonus, and you regain all expended uses when you finish a long rest.
