Goliath

Powerful Build. You count as one size larger when determining your carrying capacity and the weight you can push, drag, or lift.   Stone Camouflage. You have advantage on Dexterity (Stealth) checks made to hide in rocky terrain.   Stone's Endurance. You can focus yourself to occasionally shrug off injury. 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. After you use this trait, you can’t use it again until you finish a short or long rest.
