Frostborn Goliath

Your frost giant ancestry and life in the frigid highlands has given you resistance to cold damage.

You can move across difficult terrain made of ice or snow without expending extra movement.

If an enemy within 5 feet of you hits you with a melee attack and you take damage, you can use your reaction to reduce the damage by a number equal to your Constitution Modifier and reduce the enemy's movement speed by half until the end of their next turn. You can use this trait a number of times equal to your Constitution modifier (minimum 1) per long rest.
