This calculator is meant for the Auto Campaign Event. This Ganjilla's Event calculator will help you calculate important things like the amount of certain event items that you might get at the end of the auto campaign event. Some of these things include the blessing bags, Chinese knots or the rose.
Update: As of 4th March 2019, we have released a new calculator. The calculator will be able to calculate the helm that the player can use or exchange in order to get generous rewards in the interface of the event.
