Wave 1: You’ll be up against two Lv 27 Black Flamii and two Lv 28 Oasis Flamii and you’ll be in control of Sharla. Remember that as Sharla, you’ll need to use her Talent Art to cooldown the rifle once it overheats, allowing you to use Arts again. Also, as Sharla is the healer of the group, keep an eye on Shulk and Reyns HP and heal when necessary. Heal Blast should be saved for when a party member is in immediate danger as it has a longer cooldown while Heal Bullet can be used more freely. Finally, you can start the Break-Topple-Daze combo with her Metal Blast Art.

Wave 2: The next wave sees you taking on two Lv 28 Leg Skeeters and a Lv 29 Crowd Flier. You can make this easier on yourself by focusing on the Leg Skeeters first and even putting the Crowd Flier to sleep if need be. Additionally, Sharla’s Thunder Bullet will deal increased damage to flying enemies allowing you to dish out some of the damage yourself.

Wave 3: The final wave is against two Lv 27 Archer Tirkins, two Lv 28 Gust Vangs and a Lv 30 Archer Tirkin. If you have a Chain Attack available, begin the battle by using it against the Archer Tirkin then focus on the flyers with Sharla’s Arts. Keep an eye on HP and heal if need be and you should have no issues with finishing off the rest of the enemies.
