In short
  • The game is free; real-money purchases are optional and go through Google Play.
  • Gems, gold, tickets, heroes, familiars, relics, materials, energy, Titan Medals, titles and mail rewards are virtual content: they have no monetary value, cannot be exchanged for money and cannot be sold or traded.
  • Hero and familiar summons give random results: the odds are always shown in the game before every summon.
  • World events, the leaderboard and the mail need a connection and our server; the public name you choose is visible to everyone on the leaderboard.
  • Refunds are requested from Google Play; your consumer rights always apply.

1. Who we are and acceptance

Arcane Tempest is developed and published by Anathema Studio, Via A. De Gasperi 43, 07041 Alghero (SS), Italy, phone +39 340 807 0536, e-mail info@anathema-studio.com, website anathema-studio.com ("we"). By downloading or using the game you accept these terms and the privacy policy. The Google Play Terms of Service also apply. If you do not accept these terms, do not use the game.

2. Age

The game is designed for an audience of at least 16 years of age (the expected PEGI rating in Europe is 16) and is not directed at children; age ratings may differ in other countries. If you are a minor, use the game and make purchases only with the permission of a parent or guardian, who is responsible for the use of the Google Play account and payment methods.

3. Licence

We grant you a personal, non-exclusive, non-transferable and revocable licence to install and use the game on devices you own or control, for personal, non-commercial purposes. The game, its code, artwork, characters, texts, music and trademarks belong to Anathema Studio or their respective owners; the game includes open-source third-party software, listed on the Credits screen.

4. Virtual content

Gems, gold, summon tickets, heroes, familiars, relics, materials (Dust, Essences, Prisms), energy, Titan Medals, titles, mail rewards, levels, stars and any other in-game item ("virtual content") are part of the licence: you do not own them, they have no real-money value, they are not refundable or exchangeable for money or goods (except where required by law) and they may not be sold, transferred or traded, inside or outside the game. Gems can also be earned by playing (stages, stars, missions, achievements, login calendar, world events, optional videos). We may change the game balance, gem prices and rewards to improve the game, without reducing the value of content already bought with real money and not yet used.

Progress and virtual content are saved on your phone and, if you use Google Play Games, in your profile's cloud save. Online feature data (public name, titles, event scores, mail) is stored on our server, linked to your installation or, when the link is active, to your Play Games profile. If you clear the app's data, use "Start over" or uninstall the game without a cloud save, your progress and the content already delivered are lost and we cannot restore them; these steps do not delete the data on the server (to delete it, see section 7 of the privacy policy). Purchases that were paid but not yet delivered (for example because the app closed) are delivered automatically the next time you open the game. Mail rewards must be claimed before the expiry shown in the message (for event rewards, currently 14 days): after that they are no longer available.

5. Real-money purchases

Purchases are made only through Google Play's billing system, at the price shown by Google Play in your currency, including taxes where applicable. The sale is also governed by Google Play's terms. At the time these terms were published, the shop offers:

  • gem packs: the first purchase of each pack gives double gems (once per pack);
  • Moon Blessing (30 days): 300 gems right away plus, every day for 30 days, 90 gems and 60 energy to be claimed in the game; gems from days you miss are kept and added to your next claim, while the 60 energy is given only on the days you open the game; a new purchase adds 30 days, up to a maximum of 180;
  • Welcome bundle: gems, gold, a summon ticket and materials; can be bought only once;
  • Victor's offer: gems, gold, summon tickets and materials; appears for 48 hours after your first victory over each chapter boss, once per chapter;
  • Special offers: bundles available for a limited time, with a maximum number of purchases per player. Content, duration, limit and price are shown in the game before purchase. Real-money special offers use the Google Play products of the shop: the product name in Google's payment window may differ from the offer's name, and the content shown in the game prevails. Any discount percentage shown refers to the normal in-game price of the same content.

With gems you can also buy gold, energy refills, gem-priced special offers and summons. The exact content of each product is shown in the in-game shop before purchase, and that description prevails. Purchased content is delivered right after Google Play confirms the payment; "pending" payments are delivered when Google Play confirms them. Purchased gems can be used only in Arcane Tempest.

Right of withdrawal. If you are a consumer in the European Union, by buying digital content you request that supply begins immediately: once supply begins (delivery in the game) you lose the 14-day right of withdrawal, as provided by Art. 16(m) of Directive 2011/83/EU (Art. 59(1)(o) of the Italian Consumer Code). Your statutory rights for non-conforming digital content are not affected.

6. Refunds

Refunds are requested from Google Play under its refund policies (within 48 hours of the purchase you can ask Google Play directly). After that, or if you have a problem with a purchase, write to info@anathema-studio.com with the order number (it starts with "GPA."): we will assess the request in accordance with the law. If a purchase is refunded or cancelled, we may remove the corresponding virtual content from the game.

7. Summons: random items and odds

Summons give random heroes (Arcane Portal) or random familiars (Familiar Den) and are paid with gems, which can also be bought with real money; hero summons can also be made with tickets or for free by watching a video. The odds are shown in the game ("Details" button) before every summon; if there is any difference, the odds shown in the game at the time of the summon prevail, including when they change for a banner or an event. At the time these terms were published they are:

Heroes (160 gems per summon, ×10 for 1,600)

RarityBase odds for each summon
SSR ★★★★★3%
SR ★★★★15%
R ★★★82%
  • Increasing odds: from the 50th summon in a row without an SSR, the SSR chance rises by 5 points with each summon (8% on the 50th, 13% on the 51st… 53% on the 59th); the 60th is always an SSR. The counter resets when you get an SSR and never expires. Taking the increasing odds and the guarantee into account, the overall SSR rate is about 3.72%.
  • Every ×10 summon contains at least one SR or better hero; the first ×10 summon contains an SSR.
  • Featured hero: in each period one SSR is "featured" and gets at least half of the SSRs (the exact share is shown on the banner); if an SSR is not the featured one, the next one will be.
  • Within a rarity every hero has the same probability, except for the featured hero.
  • Tickets can be used only for single hero summons. Summons with tickets or free summons have the same odds as summons paid with gems.
  • A duplicate lights up a constellation of the hero you own, up to the sixth (C6); beyond that it turns into gold.

Familiars (100 gems per summon, ×10 for 1,000)

RarityBase odds for each summon
Legendary5%
Rare30%
Common65%
  • Increasing odds: from the 32nd summon in a row without a legendary, the chance rises by 10 points with each summon; the 40th is always a legendary. The counter is separate from the hero counter and never expires. Overall legendary rate: about 6.03%.
  • Every ×10 summon contains at least one rare or better familiar.
  • Within a rarity every familiar has the same probability.
  • A duplicate raises the familiar you own by one level, up to level 10; beyond that it turns into Dust.

Summons are not gambling: you never win money or items with real-world value.

8. World events and leaderboard

  • World events need an internet connection and our server. Times (currently every day at 8:00, 13:00 and 20:00 Italian time, for 60 minutes), number of attempts, teams, durations, bosses and rewards may change and are shown in the game.
  • The world boss's hit points are shared by all participants. Your score is the sum of the counted damage of your attempts. Without a connection you can only play training mode, which does not count for the leaderboard.
  • Rewards (for participation, grade and rank, plus a shared reward if the boss is defeated) are calculated by the server when the event closes and delivered to your mail: they must be claimed before the expiry shown. Results sent when the event has already been closed for a few minutes may not be counted.
  • To keep the leaderboard fair, the server applies plausibility limits: damage beyond these limits may be reduced or not counted. In case of irregular scores, cheating or abuse we may exclude results from the leaderboard and cancel rewards, Medals and titles. If you think one of your results was excluded by mistake, write to us.
  • Rewards, Titan Medals and titles have no monetary value. Medals can be spent only in the Titan Shop.
  • An event may be cancelled, postponed or interrupted because of technical problems or maintenance; in those cases we may, at our discretion, send compensation to your mail.
  • Event reminders are optional and can be turned on or off under Settings → Event reminders.

9. Online account and public name

For the online features the game automatically creates a pseudonymous guest account (with no real name, e-mail or password) linked to your installation and, when the link is active, to your Google Play Games profile. If you change phone or clear the data without an Android backup or a Play Games link, the online account (name, titles, unclaimed mail) may not be recoverable; your game progress follows the rules of section 4.

Your public name is visible to everyone on the leaderboard. It must be 3 to 16 characters long (letters, digits, spaces and the signs . _ -). Names that are offensive, vulgar, discriminatory or sexual, that contain personal data (yours or someone else's, such as a real full name, addresses or phone numbers), that impersonate Anathema Studio, its staff, other players or well-known people, or that contain advertising or web addresses are not allowed. An automatic filter blocks some of these names, but you remain responsible for the name you choose.

We may change a name that breaks these rules without notice and, in serious or repeated cases, suspend access to the online features. You can report a name by writing to info@anathema-studio.com. You can ask for your online account to be deleted at any time (privacy policy, section 7).

10. Video ads

The game offers optional video ads provided by Google AdMob, which you watch only if you choose to, in exchange for a reward shown before the video. The number of rewarded videos per day is limited. If a video is not available or is not watched to the end, the reward may not be granted. We are not responsible for the content of third-party ads, but we ask Google not to show ads unsuitable for the game's audience.

11. Google Play Games

Signing in to Google Play Games, achievements, Play Games leaderboards and the cloud save are optional and provided by Google under its own terms. Play Games leaderboards show your gamer name and scores, according to your Play Games profile settings. When the feature is active, the game links your online account to Play Games so you can find your name, titles and leaderboard on another phone. We may remove clearly irregular scores.

12. Rules of conduct

You may not: modify the app, its data or the requests sent to our server to gain an advantage; use cheats, bots or automation tools, including in world events; use several devices or accounts to multiply event rewards; exploit bugs in the game, the server or purchases; overload or attack the server; circumvent Google Play protections or checks; decompile or reverse-engineer the game (except as the law expressly allows); use the game for unlawful purposes. In these cases we may cancel content obtained irregularly, remove scores and titles from leaderboards and suspend access to the online features.

13. Updates, availability and end of service

We may update the game and add, change or remove content and features. Some updates may be required to keep playing (the game tells you and takes you to Google Play). The online features (world events, leaderboard, mail, special offers, news) are provided subject to availability and may be interrupted for maintenance; other features (purchases, videos, Play Games, cloud save) need an internet connection and Google's services. If we ever shut down the online features, the game or the shop, we will announce it in the game at least 30 days in advance and stop selling virtual content from that moment; your statutory rights are not affected.

14. Liability

The game is provided as is, to the extent permitted by law. We are not liable for interruptions or data loss caused by events outside our control (for example third-party services, network problems, device failures or data deleted by you). Nothing in these terms limits our liability for wilful misconduct or gross negligence, for personal injury or in any other case where the law does not allow it to be limited, nor any mandatory consumer rights.

15. Changes to these terms

We may change these terms for legal or technical reasons or because the game changes. We will publish the new version on this page with an updated date and, for significant changes, let you know in the game. Changes do not apply to purchases already made.

16. Governing law and disputes

These terms are governed by Italian law. If you are a consumer, you keep the protection of the mandatory rules of your country of residence and may bring proceedings in the courts of the place where you live. Before starting any action, please write to us: we will try to solve the problem quickly.
