Attunement: Requires attunement by a druid or warlock. Properties: While attuned, you gain darkvision out to 60 feet. If you already have darkvision, its range increases by 30 feet.
You can cast Darkness without expending a spell slot once per long rest.
As a bonus action, you can use the amulet to create difficult terrain in a 10-foot radius of jagged stone for 1 minute.
