Description
Wondrous item, uncommon (requires attunement by a Spellcaster).

The Lorehold Primer is a magic textbook created at Strixhaven's Lorehold College. The primer has 3 charges, and it regains 1d3 expended charges daily at dawn. If you make a Intelligence (History) or a Intelligence (Religion) check while holding the primer, you can expend 1 charge to give yourself a 1d4 bonus to the check, immediately after you roll the d20. In addition, if you study the primer at the end of a long rest, you can choose one 1st level spell from the Cleric or Wizard spell list. Before you finish your next long rest, you can cast the chosen spell once without a spell slot if you are holding the primer. Your spellcasting ability for this spell is your choice of Intelligence, Wisdom, or Charisma.
