Blizzard has announced a short PTR testing window for the first raids of The Burning Crusade Classic, giving players the opportunity to jump back into some of the most iconic PvE content in WoW history.

From December 19 to December 22, players will be able to test Karazhan, Gruul’s Lair, and Magtheridon’s Lair on the Anniversary PTR, helping Blizzard validate encounters, tuning, and potential issues ahead of release.

As usual, Blizzard is actively encouraging player feedback during this testing phase.

PTR Raid Testing Details (Official Announcement)

Burning Crusade Classic Raid Testing Dec. 19–22

We’ll open the initial Burning Crusade Classic raids for PTR testing on
Friday, December 19 at 12:00 p.m. (Noon) PST.

Please join us in checking out Karazhan, Gruul, and Magtheridon, and
thereafter, leave any feedback you may have in this thread.

The raids will close on the PTR on Monday, December 22 at
12:00 p.m. (Noon) PST.

What’s Available for Testing

• Karazhan – 10-player raid, featuring iconic bosses like Attumen, Moroes, and Prince Malchezaar
• Gruul’s Lair – 25-player raid with High King Maulgar and Gruul the Dragonkiller
• Magtheridon’s Lair – 25-player raid focused on coordination and cube mechanics

Testing these raids early allows Blizzard to spot mechanical issues, bugs, and balance concerns before they hit live Classic servers.

If you participate in PTR testing:

• Run full raid clears if possible
• Report bugs, odd mechanics, or tuning concerns
• Share performance and difficulty feedback on the official forums
