Fairy Tail game works using real time with the game clock running at GMT+8. This affects replenishing Physical (Stamina) points, resetting the daily count on activities such as Training Door, Plunder, and Roulettes and allows for set timed events.
There are two "meals" available per day. Each meal gives 30 physical points, if you manage to receive both meals than the second meal will restore 60 instead 30 physical points - meaning a total of 90 additional points!
First meal: from 10:00 to 13:00 (Hongkong time)
Second meal: from 17:00 to 20:00 (Hongkong time)
If you live in Germany/France/Spain/Denmark/Austria:
First meal: from 03:00 to 11:00 (MESZ)
Second meal: from 11:00 to 14:00 (MESZ)
Every day at 20:30 (14:30 in german/france/spain/denmark/austria time) there is a question event that occurs in the world chat. The first 15 right answers get a 20 diamond award. Normally you will have the chance to answer 10 times - this means you can get 200 diamonds from this event.
This event is necessary for the award "First answer in chat"
