You have resistance to cold damage, and can live in temperatures up to -40 without any adverse affects.

As an action, you can unleash a horrific roar. Each creature within 30 feet of you that can hear you must succeed on a DC 8+charisma+your proficiency bonus Wisdom saving throw or be frightened for 1 minute. A frightened target can repeat the saving throw at the end of each of its turns, with disadvantage if the affected can hear you. If a target’s saving throw is successful or the effect ends for it, the target is immune to Tyrant's roar for the next 24 hours. You may use this ability a number of times equal to your proficiency bonus, and regain all charges on a long rest.

You are a Humanoid.

You are Medium.

Your walking speed is 35 feet.

You have tough, scaly skin. When you aren’t wearing armor, your base 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.
