Guide
The Experiment 12-B can drop from Ultraxion in Dragon Soul on roughly a 1% drop rate. Raid difficulty or raid size does not change the drop chance of this mount (excluding LFR). Also in this raid can drop the Blazing Drake and the Life-Binder’s Handmaiden.
The entrance to Dragon Soul can can be found in the Caverns of Time in Tanaris. A portal was added to the portal room in Orgrimmar and Stormwind, for Horde you’ll need to go to the lower section of the portal room to find it.
Once at the Caverns of Time, follow the path down to the main section of the Caverns of Time where multiple Dungeon and Raid entrances are located. The raid will be on your right side.
Ultraxion is the 5th boss of the raid and unfortunately you must defeat the first 4 bosses to reach Ultraxion.
The first 4 bosses are trivial for a character at or above level 100 but reaching some of them make pose confusing.
Defeating the first boss is simply just running straight after entering until you reach Morchok. After that head inside to Wyrmrest Temple and on your left and right you will notice a drake illuminated in light. Each of these drakes will take you to a boss and both must be defeated before you can proceed.
Once you have the first three bosses defeated you will be returned to Wyrmrest Temple once more. Here you will now find a Red Drake in the center, this will take you to the top of the temple.
At the top of the temple you will speak to Kalecgos, this will open a portal taking you to the 4th boss after a bit of RP. Once inside the portal, click on the Focusing Iris in the center to begin the waves and trash and to eventually spawn the 4th boss, once defeated you can leave.
You will be back at the top of Wyrmrest Temple once more. Continue the dialogue with the NPCs here and eventually you will be able to talk to Thrall to begin the next wave of trash, which will lead into the spawning of Ultraxion.
Now that Ultraxion is finally here, you can engage and defeat him for a low chance at the mount which will be inside the Less Cache of the Aspects
Extra Tips: Since you can only clear the raid once per week per character, run the raid on your alts to have more than one chance per week.
