Using a Monster Life Gem Coupon adds Monster Life Gems to your account. Depending on how the coupon is acquired, it may be added to your character's inventory or delivered directly to your Monster Farm.
Cash Shop Purchase
Monster Life Gem Coupons purchased from the Cash Shop are added to the account's Monster Farm inventory. The coupon is not delivered to the Cash Inventory or character inventory. Visit your Monster Farm, navigate to the Decorate Farm tab and open the Decors and Useables section to view the coupon.
Monster Life Gem Coupons purchased from an in-game vendor are delivered to the USE inventory tab of the character that purchased them. Double-click the coupon to gain a second coupon in the character's CASH Tab. Using the second coupon delivers a new coupon to the Decorate Farm tab in the Decors and Useables section.
