Quest 1

Switch to Ann and target the two enemies grouped together at the back on your left.

Select Morgana and target the two enemies in the sandbags to your right to bring them out of cover.

Switch over to Erina and end the turn. This will make her “charge” and allow her to down the enemies caught by her gun in her next turn regardless if they have “resist” above their name.

When you end your turn, two more enemies will appear as reinforcements, and you’ll have to defeat all of them in this turn or the quest will fail. Switch to Erina, and position her, so she targets the two enemies close to her in the left sandbag. This will give her a One-More, and you’ll get another turn with her.

Now it’s time to set up an all-out attack. Position Erina at the sandbag on the left, Ann opposite her on the other side of the sandbag, and then move Morgana to the center of the right sandbag. This should defeat the majority of the enemies, and will still leave you with two attacks minimum, maybe more if you get a critical hit.

Select Ann and cast Agi on the group of enemies in the right sandbag, and you should defeat a couple while leaving the other two at low health, and without cover.

Finally, use Morgana to clean up the remaining enemies. You can do this by casting Magaru, or if you want to be safer, shooting the enemies who’re not downed to get another turn before using the spell.
