When linking is useful
Link when you intend to launch the same Global account through both official PC launchers. Use the account prompts and support instructions shown by the official service.
What linking does not do
It does not merge Korea or Taiwan characters, purchases or progression into the Global service.
Protect your account
Use only the official AION 2, NC or Steam account pages. This guide does not recommend bypassing regional authentication or using third-party account services.
