There is a thin path leading east of the evil artifact on the world map, which will bring you to Marsh End. Upon entering, Kanata will mention that the vulcosuit signal shows that the others are around this area. Head south when you gain control and break the big rock, if you want, although there’s nothing under it. To your right is something in the water that is lost, but upon inspecting it, you see that you can’t restore it right now. Ignore that direction and continue south to find a gap that you can’t cross. Get to the end and look at it to have Van shoot down the rock structure to your left, creating a full bridge you can now cross.
To the south are some enemies and you don’t have a choice in fighting them, as they drop the needed memories to progress. The Frausyn are fairly easy and weak, plus you need the Moss Memory they drop. With some on you, go ahead and restore that boulder, which allows you to continue east. Follow the path as it heads south, with more enemies awaiting your two-manned party, then keep going to another gap. Restore the rock, then have Van shoot it down to let you cross.
East is another pack of monsters, then north will have a split path. Going east here will place you in an empty area with some rocks (glitter underneath one) and a fishing spot. Going north will bring you to an opening that has some fog blocking your progress. It turns out to be an ambush of an enemy called a Gasduck. These enemies are more annoying than lethal, since a high enough defense will make their peck attack do next to no damage. The reason they are annoying is that they can inflict sleep, which is troublesome considering the numbers advantage.
Once the Gasducks are finished, you can go through the opening, but don’t do that just yet. To the left of it is a ladder you can climb to reach the ledge above the opening. Go west to find a chest that is locked, as well as ledges you can drop down (the sparkle can be a Creamy Avocado, which the chef needed in Wyllia). Return to the ledge above the opening, but head east this time and drop down to the area below at the end. You’ll find another rock formation you can restore from its lost state, which you can then have Van shoot to form another bridge. Clear the Gasducks north of the rock, then restore the chest at the top to get a Berserk, which is a hammer for Dianto. Double back to the opening, heal and save, then prepare for a boss fight.
BOSS - Morfos
Considering you only have two party members here, the boss isn’t too bad, but it can be a bit annoying. Not only can she confuse/charm you with Butterfly Wink, but she can also heal herself with Regen Powder and/or Healing Powder. It seems she can only use the healing skills once during the battle. Bash involves her flying into you, dealing around 35-40 damage, while Gust of Wind will hit both for around 30 damage. Acid is probably her most damaging move, at around 45-50 damage, but it only hits a single character. By far the most annoying skill in Morfos’ arsenal is Metamorphosis, where she’ll change into one of your party members.
She can change into any of the sidelined characters, as well as Kanata or Van. Not only does she know all of that character’s skills, but you’ll need to attack them in order to make her revert back to the butterfly form. To make matters worse, the damage inflicted doesn’t count towards her actual life bar, and should she happen to turn into Kanata or Van, then the damage you deal to that mirage is reflected back to that character. Luckily, it appears she will only turn into each character once and when she’s finished with the last one, then she won’t use Metamorphosis anymore.
Since you only have two characters, you will want to be extra careful, especially to avoid the confuse/charm situation. If one of them does get an ailment, quickly use a Panacea on the others’ next turn to cure them. Outside of that one key point, this boss fight is mostly that of attrition. None of the boss’ attacks are really worrisome for damage, but keep an eye on their health nonetheless. You can always mitigate damage further with Kanata’s Calamity, or even use Guardian to negate all damage for a turn or two. Eventually, Morfos will go down and you will emerge victorious.
Once the battle is over, you’ll get a few new artifact knowledge, like Pantheon, Foresight, Oddity, and Devotion. Your other party members will be free from their restraints and join back up with you. You should have received a Flutter Key as your main spoil from the boss fight, which you can use to open the locked chest on the ledge above the opening to nab a Dancer’s Garb. You have one more thing to do, so exit the dungeon and return to that artifact near the town. Inspect it and change it to another artifact to cure the village, and also restore the lost here.
With all that done, return to Wyllia and make your way back to the previously unfinished bridge, which is now complete. You’ll emerge on the northern side of Wyllia, where you’ll want to check the eastern dead end prior to the stone arch to find the Mech Fort artifact knowledge. Also, there is another spritnite column north of that, which unlocks Galdra’s Paradigm Drive, Featherfeet. In addition to that, you unlock the Slicing Blade link skill and the Constantia artifact knowledge. Enter Mirror Lake to the north to continue.
