Your Intelligence score is 19 while you wear this headband. It has no effect on you if your Intelligence is 19 or higher without it.

This tiny vial contains magic perfume, enough for one use. You can use an action to apply the perfume to yourself, and its effect lasts 1 hour. For the duration, you have advantage on all Charisma checks directed at humanoids of challenge rating 1 or lower. Those subjected to the perfume's effect are not aware that they've been influenced by magic.

Keoghtom's Ointment

Wondrous item, rare (requires attunement by a wizard)

To you, this book is a magical spellbook. To anyone else, the book appears to be a volume of verbose romance fiction. As an action, you can change the book's appearance and alter the plot of the romance.

When found, the book contains the following spells: Hallucinatory Terrain, Major Image, Mirror Image, Mislead, Nystul's Magic Aura, Phantasmal Force, and Silent Image. It functions as a spellbook for you.

While you are holding the book, you can use it as a spellcasting focus for your wizard spells.

The book has 3 charges, and it regains 1d3 expended charges daily at dawn. You can use the charges in the following ways while holding it:

If you spend 1 minute studying the book, you can expend 1 charge to replace one of your prepared wizard spells with a different spell in the book. The new spell must be of the illusion school.
When a creature you can see makes an Intelligence (Investigation) check to discern the true nature of an illusion spell you cast, or makes a saving throw against an illusion spell you cast, you can use your reaction and expend 1 charge to impose disadvantage on the roll.
