Birthday event
The Birthday event is a holiday event that happens yearly and takes place starting April 8th at 10AM UTC lasting one full week, ending at April 15th at 10AM UTC. This event involves the community donating 
Birthday balloons towards a community supply. Based on the total number of birthday balloons donated to the supply, new milestones will be reached resulting in all players receiving an experience boost. Birthday balloons will be removed hourly depending on the current milestone and are able to be bought with gold on a 1:1 ratio or from the Shop. The experience boost bonus is stored in an experience bank which can be claimed during the event, but if unclaimed, it will automatically be given to the player after the event.
In addition to purchasing Birthday balloons, players have a chance to earn them through the following methods:
