The subject of this article or section is part of Love is in the Air, a seasonal event that lasts two weeks. Once the event has run its course, this will no longer be available until next year, but there are no guarantees.
This does not count as a Battle or Guardian Elixir, and so stacks with elixirs and flasks. It also stacks with scrolls and most other buffs.
Despite not being labeled in the tooltip as "Requires 'Love is in the Air'" in the way certain other items are, this item is set to disappear when the event ends. Thus, while they can be traded, they may not be mailed.
