This consumable is used to enhance a Treasure without using Coins and Enhancement Stones or Treasure Enhancement Tickets, the player is allowed to decide whether to enhance using Treasure Tickers or Enhancement Stones or their Guaranteed Enhancement Oil. There is a high chance of failure when enhancing Treasures, and the odds of success are not effected by whether a Ticket or Stones are used, however, This Limited Item can be used for enhancing a Treasure with a 100% certainty.

Guaranteed Enhancement Oil are one of the rarest consumables in the game, and unfortunately are needed in large amounts due to the required amount needed to Upgrade one treasure, which needs a higher amount for higher levels of enhancements. Even with crafted tickets, it is not feasible to fully enhance all useful Treasures with Enhancement Tickets alone. A mix of Tickets and Enhancement Stones must be used.

Until a newer levels at least one Treasure to level 12, they cannot use their Guaranteed Enhancement Oil, however, since they are a very limited resource that is hard to obtain, and they will find Enhancement Tickets and Treasure Stones to be more practical as these aren't solely tied to crafting events to obtain them in the Magic Laboratory.
