The Underground Chamber Strategy

1) Split the party

Assign one unit to sneak their way through by following the path on the right. Since the majority of enemies on this path rely on attack, you need a ranged unit with high defense for the job. For instance, you can have Shamir take the warp pad. You can thin out the enemies quickly in order to prevent the battle from reaching the turn limit.

2) Place Byleth on the frontlines

Byleth functions as a powerhouse and can initiate by drawing the enemies’ attention due to his/her high stats. Have the rest of the students follow along with their ranged attacks while taking care to avoid stepping on red tiles. Byleth can soak damage by defeating the soldiers guarding the path near the door as well.

3) Assign ranged units to pick off weakened foes

Ranged units can snipe foes that are weakened during the enemy phase. Your best bet is to sandwich the ranged units between his/her classmates to take advantage of the support bonus.

4) Stick to the corners

Some ranged units, including Byleth, can also snipe distant foes from behind the wall to whittle them down. However, since they are prone to being dealt with during the enemy phase, be sure to check the enemy composition. For example, you can assign units that have high Res when sticking to corners with enemy casters. Conversely, if the enemy on the opposite side wields a bow, have a ranged unit with high Defense occupy those tiles instead.

5) Spread out

In conjunction with assigning some units to stick to the walls, you should be able to rout all enemies by having your students spread out. Units with lackluster defenses should be sandwiched in between others for linked boosts. You can also have a healer accompany them for survivability.

6) Unlock the doors

Whoever obtained the Door Key through combat should use it. To unlock the door, occupy the tile in front of the gate and select “Door.”

7) Patch up any weakened allies

Check your party’s health frequently. Don’t forget to use a healing spell or consume a Vulnerary to restore some health.

8) Rethink your moves with the combat forecast

When you’re about to engage in combat, you can take a peek to see if your unit can knock the enemy out on that turn. Since you’re on a timer during this mission, always check for an opportunity to knock them out in a strike or two to save turns.

9) Operate the lever

Don’t forget to use the mechanism to disable traps. You can then defeat the remaining soldiers to complete the mission.
