Hello La Taler's
Sorry for the inconveniences that 100% exp and 100% item drop rate event wasn't able to be progressed on 6/12. We will manage to run these 2 events on 6/15 at the same time we are supposed to run the event.
For the event time for both exp and item drop rate event, please refer to our event page in our official La Tale site.
