Bound Hero Battle: Cecilia & Lilina

Everyone has wom 2, Camus gets fortify and hone calvary buff & has moonbow, grani's shield, and quickened pulse. Xander is just there for hone calvary. Use Camus to kill the lance cavalier and red mage on enemy turn. Move Camus to safety, then back azura, Reinhardt, and Xander into the corner & out of enemy range and end turn. Teleport Reinhardt next to Camus to attack Cecilia, then teleport azura next to Reinhardt to kill her.

basically xander (G tomebreaker) kills Cecilia, while LV. 5 Reinhart (lancebreaker) kills everyone else with help of dancers.

All units 5 star except olivia, she's 4 star, but all she does is dance and give buffs.

VERY IMPORTANT to have hp seal on tharja and fortify res seal on Olivia, otherwise cecilia can take out tharja.
First turn: move everyone up one space so you have cordelia top left, tharja top right, olivia bottom left, klein bottom right.
Second turn: Move Cordelia into the corner on the right and use oliva to dance her down to take out the cavalier. Use tharja to reposition Olivia to safety.
Third turn: kill red mage with cordelia, the bowman with tharja, the pegasus rider with Klein, then dance klein so he can kill lilina.
The following enemy phase cecilia should attack klein, he'll survive with a little bit of hp and kill her on the following turn.

Started with units in the positions: Celica 1, Reinhardt 2, Azura 3, Xander 4. Move all units up 1 space while breaking the wall with Reinhardt. Next turn move up Reinhardt to nuke the lance. Celica uses Draw Back on Reinhardt. Azura dances for her (on the right of Celica) and Celica uses Draw Back again on Reinhardt. Xander doesn't move. Next turn, Celica nukes Cecillia. Reinhardt nukes the lance cavalier. Azura dances for Reinhardt (while below him). Reinhardt nukes Lilina. Xander Repositions Reinhardt out of danger. Next turn, Xander moves 2 spaces to the left. Azura dances for him. Xander attacks the bow unit. Celica finishes off the bow unit. Reinhardt nukes the red mage.

Reinhardt (-Hp, +Def)
Dire Thunder, Reposition, Moonbow, Death Blow 3, Lancebreaker 3, Threaten Res 3, Quickened Pulse

Xander
Siegfried, Reposition, Bonfire, Attack 3, Quick Riposte 2, Hone Cavalry, Hp 3 Seal

Celica (-Hp, +Atk)
Ragnarok, Draw Back, Draconic Aura, Life and Death 2, Renewal 3, Threaten Res 2, Speed 1 Seal

Azura (40+1, +Spd, -Res)
Sapphire Lance+, Sing, Moonbow, Fury 3, WIngs of Mercy 3, Hone Atk 3, Squad Ace A

This build hinges around a +atk Cordelia and a WoM dancer to cheese this map.

Cordellia must have +atk nature with atk seal and Death Blow, plus Galeforce. This coupled with Goad Fliers from Camila from across the wall will allow her to one shot the lance knight without taking damage.

Takumi (or whatever archer/mage you want to use to duel Liliana) just needs Smite to push her in range turn 2.

She can then kill the red mage next turn (after taking his double), Azura can port over and galeforce will activate, allowing her to kill the archer she baited in the same turn.

Spring Camilla should bait Cecilia with QR and kill on turn 4. Any flier can really fill her role, but it may mess up agro priority. Takumi or replacement can kill Liliana or duel her into WoM range to set up Azura.

Cordelia kills the pegasus knight as it agroes to her.
