Yeah Fate has several. There's QP, your basic run of the mill currency for powering up your characters and craft essences. Laughably easy to obtain. There's Mana Prisms, which are also fairly easy to obtain. They can be used to purchase Summon Tickets for the gacha or for like specific power ups. You can get up to 30 every day just by completing quests and if you sell high enough rarity craft essences or characters you can get them that way too. Then there's Saint Quartz, our first tier of paid currencies. Again, not too too hard to obtain. If you log in every day for a week you'll get one. If you complete story and side quests you'll get one the first time you complete said quest. Certain character specific quests offer them. They give them out in larger amounts for when the app goes down for maintenance or other special events. And by completing a special set of quests that updates weekly, you can get shards of them that with seven shards you can form one. Then there's Rare Prisms that can only be obtained by selling a 4 or 5 star servant (aka the really rare ones). I think these are purchasable but I've never looked. Then there's Unregistered Spirit Origins. These are pay only currencies. In theory, the way you obtain them is you'll get one every time you get a 5 star servant that you've already obtained five times previously, but the only way to get a five star servant that many times is by paying.
