Every currency, and what it buys
Astellia 2 runs on more than one currency, and the shop sells more than one kind of thing. The distinction that matters is between what you earn, what you buy, and what the game describes as still being designed.
The currency table
| Currency | How you get it | What it is for |
|---|---|---|
| Gold | Play, quests, rewards | Ordinary in-game purchases |
| Diamonds | Shop | Premium purchases |
| Mileage | Earned alongside Diamond spending | Secondary shop items |
| ATRA | Gameplay, Atra Pass missions, ranking | In-game currency tied to the token layer |
| Astra | Reward grants | A reward currency in the launch item list |
Five names, three functions: ordinary money, premium money, and the token-linked track. The launch rewards hand out Gold ×1,000,000, Astra ×100 and Seven Star Fragments ×30, which tells you the game intends to be generous with the ordinary currencies and careful with the premium ones.
What the shop sells
The Google Play listing discloses in-app purchases including random items. In practice that means the shop contains summon-style purchases — astels and avatars — alongside whatever convenience items exist.
The pre-registration reward list is the clearest map of what the game considers valuable, because it gives away exactly the things it would otherwise sell:
| Reward | What it hints at |
|---|---|
| Class Selection Avatar Summon Ticket | Avatars are summoned, and class choice matters |
| Astel "Papilla" Guaranteed Summon Ticket | Astels are summoned, with a guaranteed tier |
| Standard Astel Summon ×11 | Multi-pull summoning exists |
| Standard Avatar Summon ×11 | Same structure for avatars |
| Superior Growth Scroll (Account) | Character growth is itemised |
| Combat Awakening Scroll (Account) | Combat power has an upgrade path |
| Gold ×1,000,000 | Gold is the everyday currency |
| Seven Star Fragments ×30 | Fragments feed something higher-tier |
| Astra ×100 | A third reward currency |
Two account-bound growth scrolls is the detail worth noticing: progression items are part of the economy, not just cosmetics.
Diamond, Mileage, and the odd couple
The tokenomics page lists a shop flow that ends in Mileage Items: Diamonds are spent, Mileage accrues, and Mileage buys from a separate shelf. This is a common Korean mobile pattern — the premium currency and the loyalty currency are deliberately not interchangeable, so spending Diamonds does not directly convert into more Diamonds.
What is not published: prices, bundle sizes, pity counters, or whether Mileage expires.
ATRA is not a shop currency
This is the confusion worth clearing up. ATRA is the in-game currency of the token system: earned by playing, connected to ranking and the Atra Pass, convertible to ATRAx on-chain with a five-minute cooldown and an optional wallet from 19 November.
It is described as having in-game uses including enhancement, crafting and the market. That is a different role from Diamonds: ATRA is produced by play, Diamonds are produced by payment.
Should you spend anything in week one?
The honest answer is: not on the summon track, not yet.
Three reasons. The game is two days old and will be rebalanced. No pity or rate information is published, so a pull has an unknown expected value. And the pre-registration rewards already hand out more than twenty summons' worth of tickets, which is enough to find out whether you enjoy the loop before paying for it.
What is worth buying, if anything, is time: a growth scroll or a convenience item has a predictable effect. A random summon does not.
A spending checklist
- Claim everything free first. Pre-registration rewards, launch mail, milestone items.
- Play to the point where the loop repeats — usually when the story quests stop scaling.
- Decide then. If the repetition is fun, the shop is a way to accelerate something you enjoy. If it is not, no purchase fixes it.
- Check the rating and the disclosure. The Google Play listing states in-app purchases including random items, which matters if the account is shared with a child.
- Keep the token separate. Do not let a shop decision turn into a wallet decision.
What is not published
No prices, no rates, no bundle contents, no pity system, no refund policy specific to the game. There is also no confirmation of how Mileage is earned per Diamond, which is the number that decides whether the loyalty shelf is generous or decorative.
This page will get a second table when those exist. Until then, treat any price list you find elsewhere as unverified.
The summary
Gold and Astra come from playing. Diamonds come from paying. Mileage is a loyalty shelf. ATRA is the token-linked currency with in-game uses and an optional on-chain exit. The shop sells random items, disclosed on the store listing, and the free launch rewards are generous enough that you can evaluate the game before spending.
Reading a shop page without prices
The shop's prices are not visible to anyone who has not installed the game, and this site does not quote numbers it cannot verify. What can be read from the outside is structure, and structure is enough to make a first decision.
There are two premium tracks, not one. Diamonds are bought; Mileage accrues alongside spending and buys from a separate shelf. That design usually means the loyalty shelf holds convenience and cosmetics, while Diamonds hold summons.
Random items are disclosed. The store listing says so explicitly, which is the honest version of a gacha label. It also tells you the summons are sold, not just earned.
The free package is large. Two multi-pulls, two guaranteed tickets and three currencies is a lot of free value for a launch — which usually means the shop's real business starts after the free track runs out.
