Since birth you have had an intimate connection with a certain number.
Benefit: When you select this trait, roll 3d6. The resulting number becomes your numerological totem and can never be changed. Once per day, when you roll your totem number on a d20 (such as an attack roll, save, or skill check), you may treat that roll as if you had rolled a natural 20 on the die.
