Bound Hero Battle: Marth & Lumera Strategy

Use a Player Phase strategy with Galeforce and repeated actions

In our opinion, a Hit and Run strategy is the best strategy for this map.

Emblem Marth can quickly defeat any foe he initiates on with his pre-charged Lodestar Rush and inflated boss stats, while Mythic Lumera is incredibly tanky and can make her allies sturdier with Dragon Monarch granting bonus stats in-combat and creating defensive terrain.

Instead of rushing head-on, we recommend defeating certain enemies and retreating, kiting the enemies as much as possible and avoiding receiving any attacks.

Bring a unit that can generate additional actions and a refresher unit. Use the offensive unit to defeat the Sword Flier and then retreat using the refresher unit and movement skills like Reposition.

The enemies will then advance, but remain out of range to defeat your units. Use the next turn to defeat as many enemies as possible, and repeat this strategy every turn.

On the third turn, the reinforcements will spawn on the topmost part of the map, while the reinforcements on the fourth turn will spawn at the bottom of the map. Keep this in mind when positioning your units in order to avoid leaving one in range of an enemy.

We also recommend bringing units specifically tailored to defeat both Emblem Marth and Mythic Lumera.

Emblem Marth is quite sturdy with his inflated boss stats, pre-charged Lodestar Rush, and Deflect Magic 3. However, he cannot retaliate against ranged foes. Use a ranged unit to attack him over and over again with the aid of your refresher unit to bring him down.

Mythic Lumera has Distant Counter (D) to retaliate against ranged foes and is incredibly bulky with inflated boss stats and her base kit. However, she cannot retaliate against units with sweep effects and has no source of Null Follow-Up to prevent guaranteed follow-up attacks.

Bring a unit that can prevent his/her foe's counterattacks and equip that unit with as much Atk and Spd as you can. Use that unit to wear down Mythic Lumera until she is weak enough to be defeated by your main force, but keep in mind her Miracle Special skill which will save her from death once.

One of the best units to bring to his map, if you have her, is Winter Edelgard. She can generate up to two additional actions with Raging Tempest and Galeforce, and creates 【Divine Vein (Flame)】 terrain to override Mythic Lumera's 【Divine Vein (Stone)】 terrain.

Winter Edelgard, when paired with a refresher unit, can quickly sweep through most of this map, defeating all the generic enemies while saving both Emblem Marth and Mythic Lumera for later. She will need some setup in order to defeat these two units, however.

Another great unit to bring is Valentine's Elise. She can prevent her foe's counterattacks with Dusk-Dawn Staff, and Holy Pressure inflicts 【Gravity】 onto multiple foes, allowing you to kite them easier.

Alternatively, use Savior units to tank the enemies

An enemy phase tanking strategy is possible in this map, but requires significant investment and a proper team composition in order to survive the highly potent offensive prowess of both Emblem Marth and Mythic Lumera.

In order to pull off an enemy phase tanking strategy, we recommend having a Near Save unit, a Far Save unit, a healer, and an offensive unit that can defeat Emblem Marth quickly. Emblem Marth is the most important enemy unit. Bring a ranged offensive unit along to defeat him quickly, otherwise, your dedicated tank units will fall after repeated attacks with Lodestar Rush.

The Far Save unit should have multiple sources of damage reduction, both from their own kits and ideally from the healer as well. The Far Save unit will take the brunt of the damage, which is why damage reduction is necessary. You can forego Guard effects and focus on increasing overall defensive power in order to increase your chances of surviving key attacks.

The Near Save unit has to be able to survive both Emblem Marth and Mythic Lumera, as they are the most threatening enemies on this map. Ideally, your Near Save unit is Blue, to obtain color advantage against Emblem Marth.

If they have a skill that can prevent their foe's follow-up attacks, they will be better equipped to deal with Mythic Lumera, who has no skill that negates this effect, rendering her Spd stat useless in determining follow-up attacks.

The Healer ideally can provide damage reduction to your tanks. If this isn't possible, equip them with the Close Guard 3 Sacred Seal and a similar effect on their C skill.

The offensive unit must be able to defeat Emblem Marth in one round. He has multiple sources of damage reduction together with Deflect Magic 3 to protect him against consecutive magic attacks. Ideally, your offensive unit has a way to neutralize non-Special damage reduction skills.

To begin, bait the enemies in by placing your units in range of the Sword Flier. Keep your units in a tight ball formation to ensure the Savior skills cover all your units.

Once Emblem Marth is in range, position your units so that the offensive unit kills him in one round while also being covered by the Savior units.

The generic enemies on this map are of no concern and can be ignored. Your Savior units will deal with them easily. Focus your attention on positioning to defeat both Emblem Marth and Mythic Lumera.
