The Final Battle

Make sure to fight with no reserves. If you're playing in Classic mode, the lives of your units will be the only thing you shouldn't waste. Forge all pieces of equipment, buy new weapons, and equip new battalions as this battle will be hard.

Chapter 21 (Church) - Tips and Tricks

Stop White Beasts from Spawning

Fire Emblem Southern Heal Tiles
Make sure to prioritize occupying the heal tile at the bottom of the map before everything else.

Use an Onager to Lure Enemies

Healers will continuously heal the golems. They will, however, approach the team if no more golems require healing after damaging them. This will lessen the number of enemy units you will face when infiltrating their stronghold.

Conserve Battalions

Conserve battalions
The Immaculate One has armor tiles like regular demon beasts. Use Battalions to destroy The Immaculate One's armor to beat her.

Do Not Rush the Battle

Fire Emblem Final Battle
There is no limit to the number of turns you have in this fight. Take it slowly to ensure that you can still have enough power to battle The Immaculate One after dispatching all the other enemies.

Abuse Protective Tiles

There are several Forest tiles and Heal tiles scattered across the battlefield. As you are severely outnumbered, placing your units smartly will greatly reduce the number of casualties you take.
