The cost for a single is 100 gems, while a multi is 1,000 gems. If you pull a character you already have maxed out, you get common shards for another shop.
After you collect 200 mileage tickets, you can use them to exchange for the current rate-up character if you wish to do so. You can also save them for the meta characters, or just the ones you like the most.
If you want to exchange mileage tickets for an Eldain character, it’s 300 tickets instead of 200.
You can use common shards to buy dupes for all the characters in the game, since there is no real limited units. Eldains use a different currency you obtain by pulling in the “weapon” banner and are more expensive to get.
Trickcal uses a card system which you can obtain in multiple places. These cards are used in combat and can be upgraded by collecting multiple copies of the same card:
Please make sure you always check the daily shop and buy all the cards available with gold. If they cost gems, it’s up to you if you want to use premium currency here or pull for more characters.
When you pull cards you don’t get mileage tickets but instead a different currency. This is the currency used to buy dupes for the Eldain characters, so it’s worth saving them and only using on characters you really like.
You can also exchange this currency for normal mileage tickets 1:1, which is not recommended. It’s a waste so please just save it.
Like most gachas, Trickcal also features a friendship banner where you can get units.
I can’t find the rates for this banner, so for now I’m going to assume it’s the same as the normal one, 3%. Make sure you add people and are always clearing their rooms after reset to get extra currency and materials.
