A Wizard with a craft value of 5 has the Crown of the Archmage (A magic object that adds 2 to craft), so their craft is effectively 7. This allows them three spells, which they’ve acquired. They land on the Cursed Glade, where craft gained from magic objects does not apply. Their craft drops to 5. The Wizard is now only allowed two spells and must immediately discard one spell (of their choice). As soon as they leave the Cursed Glade, they can use the Crown of the Archmage again and may once more have up to three spells so long as they can acquire another.
