Berschonne's False Fundament

With a touch, you place an illusion on an object that is not being worn or carried in order to deceive reality. For the duration, you alter the object's properties in one of the ways listed below. If you cast this spell on the same object and use the same option in the same way every day for 30 days, the spell lasts until dispelled.

• If the object is a magic item with a class restriction for attunement or spell lists, the class is replaced by another class of your choice.
• If the object is a magic item with an ability score requirement for attunement, the ability—but not the score—is replaced by another ability of your choice.
• If the object is a weapon or tool, it is treated as a different weapon or tool of your choice for the purpose of determining proficiency and mastery properties.
• If the object is armor, it is treated as a different type of armor of your choice for the purpose of determining armor training.

Any attunement to the object ends when the spell ends.
