Re: (Nutaku) PeroPero Seduction
When you spin a random encounter, the enemy will have a certain number of focus points they will require to be defeated. You have to spend this many focus points to beat the enemy, regardless of your SED.
When you defeat the enemy, you get either a key or a box equal to the strength of the enemy you defeat (pink, silver, or gold). If you get a box it goes on a list where your friends will see it. To open it, a friend has to have a key of the matching rarity and you can both get a prize from that box. If it's not opened, the box times out and no one gets to have it.
In the JP version, keys can also be bought alongside gacha tickets. N tickets will have pink keys, R tickets come with silver tickets, and gold keys are packed with event gacha tickets.
Prizes can range from coins to wild cards to N and R tickets, and there's usually one SR card that can be found in the boxes until the event ends.
