After spending a Long Rest in your Bastion, you gain a magical Charm (see "Supernatural Gifts" in chapter 3) that lasts for 7 days or until you use it. The Charm allows you to cast Identify without expending a spell slot or using Material components. You can't gain this Charm again while you still have it.
