PHASE 1

Pretty standard “no gimmick, just damage until phase 2” phase. Though, you have to do this within a set number of turns or Kaiser Dragon will use Nightmare Meltdown.

PHASE 2

A Crystal will spawn. This Crystal will aid your party if you interact with it correctly.

During this time, Kaiser Dragon will do a “Barrier Shift” and gain an elemental weakness. Kaiser Dragon will also use abilities that has the same element as his weakness. This is where the Crystal mechanic comes in.

If you use the particular element that Kaiser is currently weak to on the Crystal, the Crystal will be charged with said element and grant your party resistance to that element, meaning you take less damage from Kaiser Dragon’s attacks, until he Barrier Shifts again.

While the Crystals help you tank Kaiser Dragon’s attacks, you don’t want to overuse the Crystal, we’ll get to that later.

Kaiser Dragon enters Phase 3 when he reaches a certain HP level (30%?)

PHASE 3

In this phase you try to defeat Kaiser Dragon as fast as possible as all his attacks ignore RES so your party will be taking quite a bit of beating if you leave him alive long enough.

This next bit is important. When Kaiser Dragon’s HP is brought to zero, he doesn’t die immediately. Instead he will cast Ultima, followed by Meltdown, and another Meltdown, in succession*. To survive this, you will yet need the Crystal’s help, again. Before Kaiser Dragon casts Ultima, the Crystal will react by granting your party a special shield that allows your party to block Kaiser Dragon’s spells. The number of times the Crystal grants the shield will depend on how many times you used the Crystal in Phase 2 — the lesser you used the Crystal in Phase 2, the more shields the Crystal will grant your party in Phase 3 (maximum 3 shields).

In fact, the Crystal has a total of 6 charges. Ideally, you want to use the Crystal a maximum of 3 times in P2, so you get full mitigation against the 3 final attacks in P3. However, if you feel that you need more help from the Crystal in P2 (i.e. using 4 times or more), you can do so. Just take note that you will have to tank at least 1 Meltdown when Kaiser Dragon dies. Thankfully, Meltdown is a fire elemental attack, which means you can reduce the damage with fire resist gear! (watch Video #5)

Also, having multiple sources of AoE heals helps a ton!

*The Crystal will always block Ultima first, followed by the two Meltdowns after. That means…

• if you have 2 Crystal charges remaining in P3, the Crystal will block Ultima and Meltdown, and you will take damage from the final Meltdown.
• if you have 1 Crystal charge remaining in P3, the Crystal will block Ultima, and you will take damage from the two Meltdowns.
• if you have exhausted all Crystal charges, you will take damage from all three spells.
