Ymir and Ascended Eir Strategy

Use a Hit and Run Strategy!

This map has no reinforcements and no refresher foes, making a Hit and Run strategy viable.

Stay out of the range of the enemy units on the first turn while repositioning your team, since the enemies will not engage until you step into their threat range. Once ready, initiate on any of the generic enemies using a ranged unit with 3 movement, and then use movement Assists, refresher assists, and Canto effects to retreat and get your units out of range.

The enemies will then approach your units but be unable to reach them. Ymir may also use Rally Up Atk+ and then retreat using her own Canto effect, placing her out of range of her allies and preventing Everliving Domain from granting them a Miracle effect.

Use the next turn to defeat as many foes as possible, taking advantage of Ymir being out of range of her allies. Prioritize staying out of range of the enemies while clearing the map, and pick the enemies off one at a time.

Alternatively, Use a Tanking Strategy!

You can also adopt a tanking strategy to clear this map, as none of the enemies in this map are too threatening except for Ymir and Ascended Eir. However, they are both Green units, allowing you to use a Red tank unit to enemy phase your way to victory.

Use the first few turns to set up your formation, and then place your tank unit in range of the enemies while keeping the support units out of range. With enough support, the generic enemies will fall in one round of combat each.

Ascended Eir may be able to survive with her Miracle effect if your tank unit cannot attack twice. To prevent this, either run Fatal Smoke 4 if you have it, or use a unit that can attack twice, either through outspeeding or through a guaranteed follow-up attack.
