Buy Crystals in Chaos Zero Nightmare by Account Login

Chaos Zero Nightmare (CZN) is a roguelike RPG with card mechanics and cosmic horror aesthetics. Developed by Super Creative and published by Smilegate, the creators of Epic Seven, the game was released in 2025 for Android, iOS, and PC via the Stove platform. According to Google Play, the game has over 1 million downloads and an average rating of 4.5, a stable metric for a gacha game in its first year.

Players take on the role of the Captain of the SS Nightmare, commanding a team of Agents on expeditions to Earth, consumed by a mysterious black fog known as Chaos. Each run in the Chaos Manifestation mode is procedurally generated, with routes, events, and bosses varying each time, ensuring no playthrough is the same. As of April 2026, the game is actively supported with regular updates, including Rescue banners, Ark City expansions, and seasonal modes, with Smilegate consistently releasing content for the EN segment of Stove.

What are Crystals in Chaos Zero Nightmare

Crystals are Chaos Zero Nightmare's premium currency. They can be obtained in small amounts through story progression and events, but the majority are acquired through direct purchase. For players who want to regularly pull on rate-up banners and collect 5★ Agents, in-game currency is essential.

What Crystals are used for:

• Rescue — summoning Agents (gacha) — 160 Crystals convert into one Signal Amplification Anchor for standard banners or Rescue Amplifier for rate-up banners. A 4★ guarantee every 10 pulls, and a 5★ guarantee by the 70th pull — standard pity for most gacha games.
• Rescue for Partners — Partners in CZN act as weapons, enhancing specific Agent stats. They have their own banner with an improved 50/50 mechanic: a 5★ Partner guarantees the rate-up.
• Aether Recovery (stamina) — Crystals can restore Aether for additional Tactical Training runs. Experienced players avoid this, as spending Crystals on summons is more efficient.
• Purchases in Ark City — a hub with seven zones (Starshine Diner, Garden Cafe, Epione Center, etc.). Crystals can be used to buy material packs for leveling up Agents and Partners.
• Prism Module Skins — animated cosmetic skins through the Observe Prism Module banner. Purely visual, no combat bonuses.
• Undetermined Ego Crystal — a special resource for improving Agent Manifest Ego, enhancing duplicate stats.

Crystals in CZN are not directly converted into a separate prayer currency — they are spent on either Anchors for gacha or shop purchases. Planning expenses is straightforward: calculate the number of pulls needed, convert to Crystals, and choose the optimal pack.

How to Buy Crystals in Chaos Zero Nightmare at the Best Price

Topping up CZN via Ashop uses your Stove account details from Smilegate. The game does not have a public UID for crediting, so a one-time login is used. Both authorization methods are supported, as used by CZN players.

Step 1 — Determine Account Type

When you first launch Chaos Zero Nightmare, the login screen offers two authorization methods:

• Email (Stove ID) — a Stove account linked to an email, created through registration on stove.com or in-game.
• Google — login via a Google account without separate Stove registration.

When placing an order with Ashop, select the option matching your authorization type. If unsure, open CZN, go to the main menu, and check the login method in the profile settings.

Step 2 — Choose a Pack in the Catalog

Available categories on the Chaos Zero Nightmare page in Ashop:

• Crystals — packs of 60, 300, 980, 1980, 3280, and 6480. Basic currency for gacha.
• Starshine Package — comprehensive progress sets: New Captain Support Kit I-II, Emergency Rescue Operation I-III, Large Scale Rescue Operation I, Rescue Operation II. Contains a mix of Crystals, materials, and items.
• Protos Supply — utility packs for account growth: Aether Supply Kit, Agent Growth Kit, Combatant Promotion Kit, Partner Promotion Kit, Regular Rescue Operation.
• Monthly Package — Coronomicon Monthly Package, a 30-day subscription with daily Crystals.

Each product in the catalog is available in two versions — for Email and Google accounts.

Step 3 — Provide Login Details

When placing an order, you'll need the login and password for your chosen account (Stove Email or Google). You’ll also need access to your email — if two-factor authentication via email code is enabled, the operator will confirm the login using a code sent to your inbox.

Step 4 — Pay with Available Methods

Available payment methods in Ashop:

• MIR bank card from Russian banks
• SBP — Fast Payment System via any banking app: Sberbank, T-Bank, Alfa-Bank, VTB, etc.
• Cryptocurrency — USDT (TRC20, ERC20), BTC, ETH

The specific active methods are visible on the payment page.

Step 5 — Receive Crystals and Change Password

After payment confirmation, the order is processed. The operator logs into your account, purchases the selected pack, logs out, and confirms delivery. Crediting usually occurs within an hour, though delays are possible during peak times. After receiving the notification, log in, check your Crystals balance, and change your password via Stove settings — a basic security practice for any login-based top-up.

Payment Methods in Ashop

Ashop accepts only methods that work for Russian players. Foreign cards, accounts with overseas payment services, or VPNs are not required.

MIR, Visa, Mastercard Bank Cards

MIR cards from Russian banks are accepted without restrictions. Visa and Mastercard issued by Russian banks follow the same processing. This is the most common payment method for buyers from Russia.

SBP — Fast Payment System

Payment via QR code or payment link through any banking app connected to SBP. Apps include Sberbank, T-Bank, Alfa-Bank, VTB, Raiffeisen, Gazprombank, Sovcombank, and others. No physical card is needed — just the installed banking app with PIN or biometric confirmation.

Cryptocurrency USDT, BTC, ETH

For players with crypto wallets — payment via USDT (TRC20 or ERC20), Bitcoin, or Ethereum. A convenient option for buyers from Belarus, Kazakhstan, and other CIS countries where MIR cards may not work in Russian processing.

Security of Login-Based Top-Up

Chaos Zero Nightmare uses Stove accounts with Email or Google authorization. The game lacks a public UID, requiring a transparent explanation for the login-based top-up.

What happens during top-up:

• The operator performs a one-time login using your provided credentials
• A purchase is made within the game/Stove store — Crystals or a pack
• The operator logs out and confirms delivery
• Immediately after receiving the notification, change your password via Stove or Google settings

What Ashop DOES NOT do:

• Does not save login and password after completing the order
• Does not share data with third parties
• Cannot take control of your CZN account even if desired: Stove accounts are protected by email confirmation, and Google accounts by two-factor authentication linked to your phone. Any attempt to change key settings requires verification via your email or phone

Recommendations for buyers:

• Enable two-factor authentication via email code in Stove settings before purchasing. This blocks unauthorized logins
• Do not use the same password on your CZN account as on other critical services (bank, main email)
• Change your password immediately after each purchase — even if the operator no longer has access, regular rotation reduces risks
• If two-factor authentication with email login confirmation is enabled, this is normal — the operator will ask for a one-time code from the email

If any top-up service asks for recovery codes, secret questions, or access to your email inbox — this goes beyond standard top-up, and such orders should be declined.

How to Spend Crystals in Chaos Zero Nightmare

Efficient allocation of Crystals in the early weeks significantly impacts progression. Below are recommendations for different playstyles.

For New Players (First 1-2 Weeks)

• Beginner Banner (Special Rescue Request) — a starter banner with a 20% discount and a guaranteed 5★ by the 50th pull. The most efficient Crystals spend early on, available once.
• New Captain Support Kit I and II — starter packs with Crystals and materials for leveling up early Agents. Provides a comfortable start without overpaying.
• Unlocking the First Potential Node — an inexpensive upgrade allowing manual selection of an Epiphany in Chaos Manifestation runs, rather than random.

For Active Players

• Coronomicon Monthly Package — a 30-day subscription with daily Crystals. The best value among regular offers.
• Emergency Rescue Operation I-III — packs for saving up for rate-up banners (Yuki, Chizuru, Sereniel, and other limited Agents). Enough for 10-20 pulls depending on the pack size.
• Partner Promotion Kit and Combatant Promotion Kit — materials for maxing out a specific Agent or Partner's stats.

For Hardcore Collectors

• Large Scale Rescue Operation I and Rescue Operation II — large packs for saving up pity on new banners
• 6480 Crystals — the maximum single pack, convenient to buy before starting a banner with a favorite Agent
• Memory Archive Exchange — in-game exchange of Moments of the Radiant Hero for a desired 5★ Partner. Doesn’t require Crystals directly but progresses faster with active rate-up banner play

The Ashop catalog includes major categories: 12 Crystal packs of varying denominations, 14 Starshine Package items, 10 Protos Supply items, and 2 Coronomicon items — totaling 38 SKUs (19 products in Email and Google versions).

Pity and Guarantees on CZN Banners

The Rescue system in Chaos Zero Nightmare has multiple guarantee levels to understand before purchasing Crystals:

• Base 5★ Chance — 1% per pull. Starting with the 58th pull, the chance increases by roughly +4.5% per pull
• 5★ Guarantee by the 70th Pull — a soft pity cap, after which the drop becomes virtually guaranteed
• 4★ Guarantee Every 10 Pulls — a standard rule, works on all banners
• Rate-Up Combatant: 50/50 — when a 5★ drops, there’s a 50% chance it’s the rate-up Agent. If not, the next 5★ is guaranteed (accumulated guarantee)
• Rate-Up Partner: No 50/50 — on the Partner banner, every 5★ Partner is guaranteed to be the rate-up

For players aiming for a specific Agent (e.g., Yuki or Chizuru on a limited banner), a safe budget is 140 pulls = 22,400 Crystals (a rate-up guarantee through accumulated 50/50). This is useful to consider when selecting a pack in the catalog.

Why Top Up with Ashop

Ashop operates as an independent payment channel for Russian CZN players who lack direct access to purchases via Stove and Google Play since spring 2022.

• Pay at the best price — MIR card, SBP via banking app, or crypto. No foreign cards or overseas accounts needed.
• Support for Both Authorization Types — Email Stove and Google. No need to reinstall or change login methods.
• 24/7 Telegram Support — operators help with pack selection, answer login-flow security questions, and resolve delays.
• 38 SKUs in the Catalog — major categories: Crystals, Starshine Package, Protos Supply, and Coronomicon Monthly Package — in Email and Google versions.
• Independent Service — Ashop is not affiliated with Smilegate, Super Creative, or Stove. A working payment channel for audiences blocked from the official store.
