Arcane Bookmark of Reconsideration

This thin strip of polished silver is etched with shifting arcane runes that subtly rearrange themselves when placed between the pages of a spellbook.

Prepared Insight:
While attuned to this bookmark, you can use it once per long rest to momentarily "realign your prepared magic". As a bonus action, choose one wizard spell you have prepared and replace it with a wizard spell of the same level from your spellbook that you do not currently have prepared. The newly chosen spell counts as prepared and can be cast normally.

The replaced spell is no longer prepared.

This effect lasts until you finish your next long rest, at which point your prepared spells return to their normal configuration.
