What should you buy?
You can skip the card gacha ticket, but I would recommend always getting the character gacha ticket since it’s 50% discount.
What should you buy?
Regarding the “Adventure coins” (thumbs up purple coins)
KR bros recommend getting gold crayons with this currency but considering how expensive is to farm and level up units, I would recommend picking up candy instead.
For spenders pick the gold crayons. Anyone else benefits from extra progression / farming.
What should you buy?
You can buy certificates (dupes) for your characters here. Buy the units you like or go for meta, it’s up to you. I would recommend saving up for meta units, but waifu is always a good pick.
Don’t go too crazy spending certificates and save for units you really like. It’s expensive to max out a character.
What should you buy (only with gold, NOT GEMS)?
Depending on how many characters you are building, you will have more or less gold. Sometimes you will skip this shop entirely, others you’ll be able to buy everything.
