Astromancy Archive

The archive has 3 charges, and it regains 1d3 expended charges daily at dawn.
•If you spend 1 minute studying the archive, spend 1 charge to replace one of your prepared wizard spells with a different spell in the archive. New spell must be of divination.
•When a creature you can see within 30 feet of you makes an attack roll, an ability check, or a saving throw, you can use your reaction to expend 1 charge and force the creature to roll a d4 and apply the number rolled as a bonus or penalty
