The WoW Classic PTR is now available, with character copy enabled for the two test realms. Phase 4 content is available to test, including the Zul’Gurub raid and Arathi Basin battleground.
To access the WoW Classic PTR, just change the game version in the Battle.net launcher at the bottom left of the screen. A prompt will pop up to install the PTR.
In the globalstrings, you’ll also find details on the WoW Classic WoW Token, which is only on Chinese realms.
