- In addition to the current email authentication 3-way login method, improved login using PIN without personal information. Selected during initial registration. - Added item drop function (currently, heroes can interact through shared storage even when they are far away, but it is not intuitive and inconvenient..) - Changed the design of Artemis, Bagatur hero skins. - Changed title/battle background music. - Other minor bug fixes. We will review other changes to the overall direction of the game (PvE content) over time. ^^
