Giant, Stage 2 (Titanic Resolve)

Titanic Resolve. When you take damage from a weapon attack, you can use your reaction to shrug off the worst of the harm. When you do, you gain temporary hit points equal to the damage taken from the triggering attack. While you have any temporary hit points granted by this boon, you have resistance to piercing, bludgeoning, and slashing damage. Once you use this boon, you can't do so again until you complete a short or long rest.

Flaw.
Groundshaker. Your steps sound like falling trees and no matter how careful you are, you almost always leave destructive signs of your passing. Creatures have advantage on ability checks made to notice you and follow your trail, and you have disadvantage on all stealth checks.
