I think you accidentally clicked on the wrong thread. This thread is about the second boss in Rabanastre, not Bahamut Ultimate /s

The only part where a failed mechanic could potentially lead to a wipe, is if one alliance has a lot of deaths right before submission tower, causing one of the sand spheres to explode.
Outside of that, a group can have at least 20-30 deaths over the course of the fight, and still be able to kill it.
