You have a +1 bonus to your spell attack rolls and spell save DC while attuned to this amulet.

Upon completing a Long Rest you can roll 3 dice (d4, d6, d8, d10, d12, or d20, with a maximum of 2 per die type) of your choice. Therefor after, you can replace any roll made by you or a creature that you can see with one of these foretelling rolls. You must choose to do so before the roll, and you can replace a roll in this way only once per turn.
