A new paralogue chapter will be available now The Instructor, its up to you if you want to play on it or proceed to Chapter 15 Dancer in the Ruins.
Your goal is to help Seadall escape, you lose the game if you are defeated or Seadall is defeated. Recommended level in this battle is level 19.
Seadall is trap inside the building and will chase down with two corrupted, there will be a few enemies that you will encounter while pushing your way to get near to Seadall.
Eliminate the enemies and destroy the stone walls that blocking your path to get close to Seadall, once you reach Seadall location, eliminate the enemies that surround him then move closer to the Dancer and choose “Talk” in an option.
Note: Some of your team units will not be able to have an option talk with Seadall so make Alear do the talk.
After the talking, you will obtain Emblem Corrin and Seadall will then join the group to eliminate more enemies.
Seadall is a dancer and you get a tutorial about his Dancing abilities. If Seadall is near with your team unit that has already acted their turn, select “Dance” in the option. The purpose of this Dance is to be able to make your team unit act again in the same turn.
Unfortunately, the gate where you and your team units entered will be close so you cant go back there to escape. Make your way to the door that is open in your left and fight the enemies.
Avoid the tiles with purple smoke that called miasma, if you end your turn in this tiles, it will lower your Defense and Resistance, the corrupted enemies will gain Defense and Resistance boost if they have their turn while standing in miasma tiles. Always end your turn about two tiles away from the miasma tiles and try to lure the enemies towards you by ending your turn in Danger Radius, the enemies will then step out of the miasma tiles and you can defeat them easily. Emblem Corrin’s Dragon Vein sync skill can help to remove miasma smoke in the tiles and change it to user’s type, but sadly it can only affect small area around the user and only Seadall can do this if he’s near the miasma tiles.
The Ice Shard will disappear together with the miasma once the enemies turn is done. Try not to provoke the enemy so that Seadall can make his way to remove miasma, remember that Seadall must not be defeated or you will lose the game. Proceed to the map in your left to reach another door that you can destroy.
Once the door is destroyed or unlocked, more enemies and miasma tiles will be reveal, plan carefully your move and lure enemies to you, defeat all the enemies that you will encounter on your way and you will see two passage way, one is is going to east and the other passage way is going to south, move few team units in south and you will encounter two enemies here and a treasure chest.
Defeat the enemies and open the chest to obtain an Energy Drop, after claiming the treasure, you need to return and proceed to the east passage way because the south passage way in a dead end.
The east passage way area has a lot of miasma tiles and a few enemies, move Seadall near the miasma tiles so he can removed it by using Dragon Vein, but make sure that Seadall is not too close with the enemies Danger Radius. Continue your journey to the south door and you will see a lighting green tiles, this will serve your exit door to escape.
Eliminate all the enemies and let Seadall clear the miasma in your way. There is a treasure chest on west area, defeat the enemy that guarding it and grab the treasure chest to obtain an item.
One of the corrupted enemy is carrying a Tomahawk weapon and a Revival Stone, so you have to defeat this enemy twice.
If the situation is inconvenient or you are having a hard time defeating this enemy, you can just make way for Seadall to the southeast exit to escape and win the game.
