As a goliath, you have the following racial traits.
- Creature Type. You are a Humanoid.
- Size. You are Medium.
- Speed. Your walking speed is 30 feet.
- Little Giant. You have proficiency in the Athletics skill, and you count as one size larger when determining your carrying capacity and the weight you can push, drag, or lift.
- Mountain Born. You have resistance to cold damage. You also naturally acclimate to high altitudes, even if you’ve never been to one. This includes elevations above 20,000 feet.
- Stone’s Endurance. You can supernaturally draw on unyielding stone to shrug off harm. When you take damage, you can use your reaction to roll a d12.

You can use this trait a number of times equal to your proficiency bonus, and you regain all expended uses when you finish a long rest.
