Greater Ring of the Pomarji

This black ring was originally created by a wizard from the Wild Coast. When you wear this magic ring, you can use a Magic Action to conjure orc spirits that appear as a Large pack of spectral intangible orcs in an unoccupied space within 60 feet of you. While you are within 5 feet of the pack, you have advantage on any Strength Test, and when you move on your turn, you can also move the pack up to 30 feet to an unoccupied space that you can see. The pack disappears after 1 minute, or earlier if you dismiss it as a Bonus Action. Once you use this property, you can't use it again until you finish a Long Rest.
