Black Qiraji Resonating Crystal



The Black Qiraji Resonating Crystal teaches players to summon the Black Qiraji Battle Tank, a legendary mount. Currently, it was the only legendary mount to have ever been added to the game for players. The Crystal is a quest reward from Bang a Gong! which required the player to use the Scepter of the Shifting Sands on the gong on the Scarab Dais during the 10 hour battle with the Silithid, which occurred during the opening of Ahn'Qiraj. This was a one time server event.

Mount Journal
Although many varieties of Qiraji Battle Tank can still be found in the ruins of Ahn'Qiraj today, the darkest of the species were only seen on the day the Scarab gong was rung.

One-time bug
If a player was logged out while mounted on this mount when patch 2.2 was deployed, upon logging in after the patch, the mount "buff" was replaced by a buff that transformed the player into a flying wasp. This was a one time occurrence, however, as there is no evidence the flying wasp buff is obtainable by any other means. However, a buff like it is available from Underbelly Elixir, possibly inspired by this bug.

During the Patch 3.0.2 PTR, the Black Qiraji Resonating Crystal had a changed tooltip which was roughly "This mount changes depending on your Riding skill and location." Upon testing this in several locations, it was found that the mount became a wasp in any zone you could fly in and the regular scarab in other zones. This functionality was removed before the patch was released.
