Astrum Academy: what it is, rules and how to leave it running on your PC

What is Astrum Academy

Portuguese-language browser RPG set in a magic academy split into four houses: the student attends classes (spells, potions, herbology, flying, defense, familiars) and faces creatures of the Forbidding Forest in fights that run on their own. It has a player market, PvP duels, a house ranking and a premium currency bought in Brazilian reais.

• Four houses — Grifiti, Sisyrin, Raviw and Hufpuf —, each tied to an essence (Sun, Moon, Sky and Earth).
• The Academy map has seven class locations: Cosmic Divination, Spells, Potions, Astral Herbology, Flying Yard, Elemental Defense and Familiar Training.
• In the Forbidding Forest combat is automatic: the character fights and uses spells and potions on its own, and the player can click to speed it up.
• The Elemental Defense Room has 10 creatures in waves, with automatic combat, and is the only place that gives Defense XP.
• Each house has three levels of its own spells, and there are two universal spells (Guiding Light and Repair); potions start from four bases, one per essence, which combine into six hybrid potions.
• There are six familiars to choose from: snake, frog, owl, rat, cat and turtle.
• At the Flea Market, in Trade Alley, players list equipment, materials and even Lumens, priced in Noxus, the premium currency.
• Noxus is bought through LivePix — 10 for R$ 5, 100 for R$ 45 and 250 for R$ 100 — and delivered manually by the team; VIP costs 5 Noxus (7 days) or 10 Noxus (30 days) and gives +30% EXP in the Forest and triple bag space.
• Progress is saved in the browser and in the cloud; without internet XP is not recorded, and the code keeps a single active session per account (logging in with the same account elsewhere ends the previous one).
• Rewards announced for the Beta: an exclusive prize at launch for those who reach level 100 and an exclusive tradable item for the top three of each house.

Do you need to keep the tab open?

The Astrum Academy site doesn't say whether the account progresses with the tab closed (checked Sep 22, 2026).

The site does not say whether the character progresses with the tab closed. According to the page's code, automatic combat happens on the game screen and XP is only recorded with an internet connection.

You can find out in an hour: note your XP or loot, close the tab, come back later and compare. If nothing changed, the game needs the page open — and a regular browser slows down or even discards background tabs (see why idle games stop in the background).

Rules: multiple accounts, automation and VPN

The Astrum Academy site doesn't publish rules on multiple accounts, automation, VPN or real-money trading (checked Sep 22, 2026). Before opening a second account, ask on the game's official channels.

• Selling items for real money (RMT): the site doesn't say. The site publishes no rules on selling items or accounts for real money. At the Flea Market prices are in Noxus, the premium currency bought in reais; the code has no Noxus withdrawal.

How to leave Astrum Academy running in IdleDeck

1. Download IdleDeck (free, Windows 10 and 11) and link the app to your IdleDeck account — it takes a minute.
2. Click Add account, go to Other game or site and paste astrum-academy.netlify.app.
3. Sign in to your Astrum Academy account in that window, just like in the browser. Each IdleDeck account has its own login, cookies and cache — repeat step 2 for each account the game's rules allow.
4. Turn on alerts: Windows notification, sound or a Discord webhook to know on your phone when the account drops.
5. You can minimize. The page stays awake with the window minimized or in the tray. If it drops, IdleDeck retries on its own; if the game's connection drops, it alerts you — and reloads on its own if you turn that option on in the settings.
