Part 1. Aion 2 Account and Login Issues (Korea & Taiwan Servers)

Aion 2 requires regional accounts, OTP verification, and sometimes platform-specific sign-ups. Here are the most common account problems and how to fix them.

1. How to Register an Aion 2 Korea Account (KR Account Sign-Up)

Players trying to register for the Korean server often struggle because the signup page is in Korean, requires full personal info, and may reject foreign phone numbers.

Solution

1. Visit the official NC Korea Purple registration page.
2. Click “Sign Up” and choose email registration.
3. Use a valid email and verify it.
4. For foreign players, skip Korean phone validation and choose email-based verification only.
5. If the login page does not load or fails due to region routing, run LagoFast Game Booster on the Purple client route to stabilize the connection.

2. How to Register an Aion 2 Taiwan Account (TW Account Sign-Up)

The Taiwan server allows email registration, but the page may return region errors, slow loading, or verification failures.

Solution

1. Go to NC Taiwan Purple registration.
2. Register using email — this is the easiest method.
3. If the verification email does not arrive, wait 3–5 minutes and check your spam folder.
4. If the page refuses to load or shows “region restricted”, connect using LagoFast Game Booster Taiwan route to fix routing and login failures.

3. Aion 2 PURPLE Login Failure

Many players cannot log in because Purple automatically redirects them to the Global region, causing TW/KR accounts to disappear or fail authentication.

Symptoms
Purple logs into Global automatically
Aion 2 does not appear in Store
Taiwan/Korea region cannot be selected
Correct password still logs you into Global

Quick Fix

• Create a brand-new email and register a new Purple account
• Select Taiwan during region/country selection
• Avoid VPNs; this is an account-region issue, not an IP issue
• If the Taiwan login page loops or fails to load, use LagoFast Taiwan routing to prevent login timeout and load the correct authentication server

3. Aion 2 System Requirements (2025)

Mobile

• RAM: 4 GB minimum, 6 GB recommended
• CPU: Snapdragon 730+ / Apple A12+
• Storage: 10 GB free

PC (via Purple emulator)

• CPU: i5-6600 or equivalent
• GPU: GTX 1050 or above
• RAM: 8 GB minimum
• Storage: SSD recommended

Part 5. Server & Region Issues

1. Aion 2 Server Overview (KR vs TW)

• Korean Servers: Host multiple realms to support a large domestic player base, often reaching high capacity quickly post-launch. They have strict login requirements and feature highly competitive gameplay environments.
• Taiwan Servers: Target Traditional Chinese-speaking players and Southeast Asian users, maintaining stable, balanced populations. These servers offer friendlier communities, more accessible queues, and avoid overcrowding while keeping gameplay active.

Given Aion 2’s focus on large-scale faction warfare and high-density zones, choosing a server with stable population and low latency is key—directly impacting queue times, guild dynamics, PvP balance, and in-game economy.

2. Unsupported Language Issues

Solution: LagoFast’s Translation Tool

• Screenshot Translation: Capture on-screen text (quests, menus) and get instant translations (e.g., KR/TW → EN/Russian/Thai) via hotkeys.
• One-Click Chat Translation: Auto-convert your messages to Korean/Traditional Chinese, and translate incoming ones for smooth communication.
