After some testing with this boss, here's a breakdown of what to do from what I can tell: After a certain amount of time has passed, Kaiser will check to see if you've completed an elemental cycle. If not, it uses Ultima and starts flipping out, eventually ending with Meltdown. I don't know if there's a way to survive at that point. However, if you have completed a cycle, then it will use Purge instead and the cycle starts anew. A "cycle" is when you hit Kaiser with each element in turn: Fire, Ice, Bolt, Wind, Water, Earth, Dark, Holy, and finally Neutral (non-elemental spell or physical attack). It doesn't seem to matter what order you use, and I'm not sure if the neutral/physical attack specifically has to be at the end or not. Kaiser will attack with elemental attacks of the element he was last hit with. Kaiser only counterattacks if you hit him with an element that you have already used this cycle. So the fight isn't really that hard, you just have to do two things: 1) Make sure every element can be hit (even if an attack fails, it still counts for the cycle) and 2) Keep careful track of which elements you've used. The party I used was Terra, Celes, Sabin, and Setzer. All elements are covered here (Storm counts for Water, Demi counts for Earth, and I was using Ultima for the neutral element). Sabin largely used Chakra to keep up MP or the occasional Mantra when healing was needed. Once a cycle was completed, I just waited for Kaiser to Purge and started again. It doesn't seem to matter how quickly you apply elements, as long as the whole cycle is completed he should use Purge. If anything is missing, you'll get Ultima instead and that's pretty much a wipe.
