What are Premium Scrolls?
Premium Scrolls are no longer available in Tibia since the release of the Store and Tibia Coins in July 2015. All Premium Scrolls that still existed at this point of time have been converted into Tibia Coins.
Premium Scrolls were vouchers for Tibia Premium Time. Whenever you used a Premium Scroll, 30 days of Premium Time were added to your account. Unlike Premium Time, Premium Scrolls could be transferred into the game as items and could be traded to other characters via the safe trade mode or the Market.
