  Official Ruling
  Protection from die rolls means the equipped creature can’t be dealt damage by, equipped or enchanted by, blocked by, or targeted by anything that allows or requires someone to roll a die. This includes any kind of dice, not just six-sided dice. This also includes anything that allows you to reroll a die.
