Experiment 12-B

Experiment 12-B 

Experiment 12-B is a drake mount that drops from Ultraxion in the raid Dragon Soul which is located in the Caverns of Time which can be easily accessed by a portal in the Violet Hold in Dalaran. The drop chance varies on normal/heroic 10/25 man, but it starts at 0.5% and the max drop chance being 1.2%. It is easily soloable both normal and heroic by most classes, though there's a phase right before this boss that is much more suited for ranged classes.After killing Ultraxion, a Lesser Cache of the Aspects will appear and this is where you will find your loot and possible mount.
