Rhea and Byleth Strategy

Use a Hit and Run Strategy!

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

The Axe Knight is in range to be defeated by ranged cavalry units on turn one while his Aegis hasn't been pre-charged by Hardy Fighter 3 yet. Do so, and then use your own refresher assists, movement assists like Reposition, or post-combat movement effects like Canto to retreat to safety.

The enemies will then approach your team but be unable to reach your units. You can use the following turns to pick them off at your leisure.

Rhea has very high defensive stats and has both Revealing Breath and True Dragon Wall to help mitigate damage. However, her Spd is very low, and she has no way to prevent follow-up attacks. Bring a unit that can pierce through non-Special damage reduction to attack Rhea and she should fall in combat.

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 Byleth and Rhea's pre-charged Specials.

The only concerning enemies on this map are Rhea with her high bulk and pre-charged Iceberg, and Byleth with Potent 4 granting additional follow-up attacks.

To combat this, ensure your tank unit has an effect that allows him/her to neutralize non-Special damage reduction effects in order to deal maximum damage to Rhea. As for Byleth, she can be dealt with similar to other Sword Infantry units: tank her damage with a high Def Blue unit, or defeat her in player phase using a Blue unit that deals magic damage.

Alternatively, bring a tank unit whose sole purpose is to soak damage, and equip them with as many defensive effects as possible. Then, bring an offensive unit that can neutralize non-Special damage reduction effects; this unit's role is to defeat both Rhea and Byleth and retreat to safety afterwards while the tank unit protects him/her from the other units.
