Tarrasque's Resilience. When you are hit by an attack that deals bludgeoning, piercing, or slashing damage, you can roll a d10. On a 1 to 6, you are affected as normal. On a 7 to 9, you take half as much damage. On a 10, you take no damage.

Reflect. If you are targeted by a magic missile spell, a spell that requires a ranged attack roll, or included in the area of effect of a line spell, you can use your reaction to roll a d6. On a 1 or 2, you are affected as normal. On a 3 or 4, you take half as much damage. On a 5, you are unaffected. On a 6, you are unaffected, and the effect is reflected back at the caster as though it originated from you, turning the caster into the target.
