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.
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.
Darkvision. Accustomed to lightless caves, you have superior vision in darkness. You can see in dim light within 60 feet of you as if it were bright light, and in darkness as if it were dim light. You can’t discern colour in darkness, only shades of gray.
Rock Steady. Like the stone from which your people derive their name, you are especially sturdy. When you use the Titan's Endurance feature, you may roll the d12 twice and select the larger number.
Sculptor of Stone. You have a natural expertise for stonemasonry. You are proficient with mason's tools.
