Legendary Hero Battle - Deirdre Strategy

Bring a Far Save Unit

A tanking strategy is possible in this map due to most of the enemies being located in one central area. The reinforcements that follow on subsequent turns are either near the central area but unable to reach the middle trees, or simply unable to reach the central area in the first place.

Ideally, your Savior armor unit can negate penalties or reverse them with Unity skills, as some enemies in this map bring stat debuffs.

Legendary Deirdre has a pre-charged Circlet of Balance which grants her a Miracle effect when certain conditions are met. To avoid this, initiate combat against her with a melee unit, ideally physical, in order to defeat her quickly.

As for your support units, bring an ally that can provide useful effects such as damage reduction and Special acceleration. These supports should have their C skill and Sacred Seal slots filled with effects that increase the bulk of your main unit.

Alternatively, use a Player Phase strategy with Galeforce and repeated actions

With six foes at the start of the match all in one general area, it is possible to use a strategy involving repeated actions using Galeforce or Duo/Harmonized skills to clear the map on turn one.

Units like Ninja Corrin (F) and Hatari Azura work wonders on this map with their respective Duo/Harmonized skills granting additional actions. Summer Edelgard also works due to Raging Storm granting one additional action, and inheriting Galeforce can grant her another.

Be wary of Legendary Deirdre carrying Deflect Missile 3 and the Lance Knight carrying the Hardy Fighter / Aegis combo and Deflect Magic 3 to protect against mages. Bring melee initiators in order to disregard these Sacred Seals.

Using powerful brave effect units like Ninja Lyn and Ninja Corrin (F) and timing their Special skills correctly, it is possible for them to brute force their way through these Sacred Seals.
