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 naturally acclimate to high altitudes, even if you’ve never been to one. This includes elevations above 20,000 feet.

Titan's Endurance. You can supernaturally draw on the might of your Giant ancestors to shrug off harm. When you take damage, you can use your reaction to roll a d12. Add your Constitution modifier to the number rolled and reduce the damage by that total. 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.

Cloud Giant Magic. You have a semblance of your ancestor's innate power. Once per day you can cast Detect Magic, Feather Fall, or Fog Cloud without expending a spell slot. Once you do so, you cannot use this feature again until you complete a long rest.

Extra Proficiency. Like your Cloud Giant forebears, you are naturally adept at handling social situations. You gain proficiency in one of: Deception, Insight, Intimidation, or Persuasion.
