Mythic Hero Battle: Nerþuz Strategy

Use a Player Phase strategy with Galeforce and repeated actions

With six foes at the start of the match, it is possible to use a strategy involving repeated actions using Galeforce or Duo/Harmonized skills to clear the map on turn one, or eliminate most of the enemies and kite the remaining leftovers.

Units like Ninja Laegjarn, Ninja Corrin (F), and Summer Edelgard work fantastic in this map with their own abilities to generate additional actions. The Ninja duos can use their Duo Skills while Summer Edelgard can use Raging Storm to create an additional action for themselves. Summer Edelgard can even equip Galeforce to get a third action!

However, due to the distance of your team from the enemies' initial spawn locations, Wings of Mercy and/or similar warp skills will be required in order to reach the enemies on turn one. Equip your initiator unit(s) with self-recoil skills like Fury 4 or Atk/Spd Push 4 in order to get them to the required HP threshold. The exception is if initiating with a ranged cavalry unit on the third column; they are able to reach both the Lance Flier and the Red Fafnir. Take note of the Red Fafnir having the Distant Counter (D) Sacred Seal to be able to retaliate back.

Key support units for this strategy include Hatari Azura and New Year Peony. These two refresher units can generate an additional action for an ally with their unique refresh skills, and another action on top of that with their own Duo/Harmonized skills too.

You may also spend the first turn positioning your allies on the safe tiles. This map triggers the enemy AI on the first turn, forcing the enemies to advance. From there, you can pick off enemies at your leisure while positioning yourself away from their attack ranges.

Be careful against the Cleric and the Blue Mage, as both units have Canto Control 3 to prevent post-combat repositioning.

Alternatively, use Savior units to tank the enemies

With the exception of Nerþuz, the enemies on this map are not too threatening. Using a Near Save unit and a Far Save unit with two support units (ideally a healer and a refresher) can also clear the map by withstanding the enemies and winning through attrition.

The Near Save unit will be key because he/she needs to be able to survive Nerþuz's attacks twice. Nerþuz will be able to trigger Galeforce through her Horn of the Land's Special acceleration and Fruit of Life's Tempo effect.

Nerþuz will not approach your team until the fourth turn unless your units are in her threat range, giving you time to clear as many of the generic enemies as you can first.

If none of your Near Save units can reliably tank two attacks from Nerþuz, we recommend bringing a unit specifically to take her down. This unit could have Beast or Cavalry effective weapons to make his/her job easier.
