• You have resistance to bludgeoning, piercing, and slashing damage.
• Whenever you deal damage or restore a creatures hit points you add your proficiency bonus to the total.

You can end this ability before the 8 hours has elapsed, no action required. Once you use this ability you must finish a long rest before you can use it again.
