PSA: White Rabbit Is In The Event Rerun
Full guide later, but for now, don’t blast through the event just yet, there’s a chance for you to get the White Rabbit summon.
You can find the White Rabbit summon here, at 3-1 / 4-2 / 5-2 in the event scenario story. You can keep starting and re-loading until the White Rabbit appears in the fight, then if the White Rabbit doesn’t appear or doesn’t drop a gold box, you can Retreat from the fight and save your AP. There is a chance the White Rabbit will drop a a dud Gold Box anyways, but it’s better to try than not.
