Peace Keeper of the Monster Forest!
Greetings, this is Legend of Slime.
On 11.13(Mon) 00:00(UTC) we have confirmed an issue regarding the items in the Slime Assemble event shop.
We are currently working on fixing this issue, and we will do our best to provide an update as soon as possible.
We apologize for any inconvenience in using the game,
and we will strive to become a Legend of Slime that works even harder.
Thank You
