The number in the upper right corner is how many PVCs you must spend to purchase the item from the shop. Victory cards and some other types of cards also have a price listed in this field.

Additionally, many cards an be acquired directly as treasure during battlegames throughout the event. A good adventurer will loot corpses and check for hidden chests!

Using an item is simple; just declare the effect and hand the card to a reeve when you get the chance. In addition to one-use items, there are items that function continuously. These relics will be available for purchase from a reeve for high prices, but some of them can be found in games as well. Relics have strong, ongoing effects.
