4th Stratum

4th Stratum Boss and Epilogue

20F - The Creature in the Cavern (continue)

Simply approach the crystal at B4 to be teleported to F4, then you'll notice a dragon in the far north, which immediately casts a teleport crystal. Before the real fight with the boss, you have to approach it first, and it isn't easy. This boss can cast teleport crystal that falls from the air, creating a shockwave upon landing. If you happen to be in its impact field, your party members will lose 100 HP (Advanced) / 80 HP (Basic) and also will be pushed backward for a maximum of 5 squares. This boss also can face diagonal in order to have better observation in casting those crystals. Remember that each teleport crystal still has its function so you can teleport to a different place if there is another one on the same line.

Anyway, if you want to quickly approach the boss without taking any damage, just follow this route.

Similar to Undead King, Crystal Dragon also has two forms: physical-based form and magical-based form. This boss will change form after certain period or condition, and each form has its own movesets.

Crystal Dragon shows up in Magical Form. While in this state it alternates between fire attack (Banefire Breath), ice attack (Frostcoat Breath), and volt attack (Lockvolt Breath). Frostcoat Breath may be the biggest threat here as it has a chance to inflict petrify. After several turns, or if you manage to deal quite a pack of damage, it'll change into Physical Form. While in this state it alternates between cut attack (Rending Claws), stab attack (Rock Bullet), or bash attack (Sonic Blow). After several turns, or if you manage to deal quite a pack of damage, it'll change into Magical Form, which repeats the cycle. This boss also has one move, Prism Laser, which hits all party members and can be used regardless of its form.

After depleting a quarter of its health, Crystal Dragon has 2 additional moves. Its Magical Form gains Clear Breath, which deals a lot of damage to all party members, and also dispels all of your buffs. To add the worse news, the damage is increased based on how many buffs that have been dispelled. Its Physical Form gains Eternal Lament, which attempts to inflict sleep as well as bind your party members' head. It's weaker than Clear Breath, but may debilitate your party from launching their best moves.

Now for the strategies. Crystal Dragon shows up in Magical Form which fortunately is slightly weak to physical-based damage. All of its movements use head so you may want to bind its head. You can't tell which element will be used next, so you may want to activate elemental defense buffs or use Fire/Ice/Volt Mist. This boss also doesn't have a high resistance to petrify, so you may want to inflict it before using any other attack. Gorgon Arrow's Gorgon Shot, Petra Flyssa, Petrify Gas, or some other skills may be picked. Once it's petrified, cast your buffs/debuffs, then launch your Union Skill and other high damage dealer moves to quickly deplete its health. After it recovers, it'll change into Physical Form. All of its moves don't pose a serious threat, and you only need to keep your health as high as possible in order to survive each attack. After depleting a quarter of its health, watch out for its Magical Form. If you have many buffs and the boss changes into Magical Form, you may want to use Unihorn to dispel your own buffs in order to reduce Clear Breath's damage. Unihorn can be bought for each Ooze Mushroom, a common material obtained at any taking point in 4th Stratum.

If you manage to defeat it while its arms are bound, you'll obtain Draco Lightwing as additional loot. There should be many options to bind arms, and Celestrian's Chain Blast Union Skill may be the best option if you also want to fully bind the boss. However, Clear Breath always becomes your biggest problem, so you may want to try it later after gaining more strength.


Upon defeating the boss, Mysterious Girl's voice can be heard, congratulating you to the success of defeating the dragon. She tells you to examine the largest crystal in the hall, which also acts as a teleporter to the next stratum. There, you'll meet with Mysterious Girl again, who reveals that her wish will be granted when someone manages to reach the top of Yggdrasil. For now, head straight and examine the Geomagnetic Pole to return to the town, then visit Council Hall to report the mission. Ramus then gives 40000 en as reward for defeating the dragon.

Interlude

Since you've landed your foot on 21F, you may want to accept all of the unlocked requests. However, I'll mention them in the bottom of the 21F section for easier reading.
