so this dragon event is essentially white rabbit farming
Yes, it's rabbit hunting season!
For all people that don't know it, in the event chapters 3-1,4-2 and 5-2 spawns a white rabbit in the first battle.
The rabbit has a chance to appear and when it appears it has a chance to drop a gold chest.
In this gold chest can be the SR white rabbit summon which increases droprates and experience gained when used as main summon, so it's a great summon when farming for stuff.
This event is the best and most efficient way to try and get your rabbit!
So the drill for this event is start quest, look if rabbit is in the first group if yes kill it and look if a gold chest drops if yes again hope that the summon drops when you finish the quest.
Should rabbit not appear or the rabbit does not drop a gold chest, go to menu on the top right and retreat from the quest. Rinse and repeat from here!
This method does NOT cost any AP and gives you 3 chances to get your rabbit!
Happy Hunting everyone!
