Damage Calculator Tool

Byleth: The Fódlan Light Strategy

Avoid Using Ranged Physical Damage Units on Byleth!

Legendary Byleth (F) has the Deflect MIssile 3 Sacred Seal, making her able to withstand attacks from both bows and daggers.

Take her out with melee physical damage units, as her Def is lower than her Res.

Watch Out for Enemy Mobility

Two of the reinforcements for this map possess Aerobatics 3, enabling them to move to a space adjacent to any infantry, armored, or cavalry ally within 2 spaces.

In addition to this, Byleth herself has a superior mobility skill in the form of Goddess Bearer.

The range of movement may catch your team by surprise so be mindful of your units' placements!

Beware of Several Debuffs

Several units on this map have invisible debuffs which will take effect during combat.

You can mitigate this somewhat by using units that buff themselves during combat and/or have allies that grant buffs during combat.

Inflicting debuffs on enemy units is also an effective strategy to even the playing field, such as using dagger units (just not on Byleth) or staff units.

Use Ash

Ash if a very effective unit on this map due to the effects of her weapon when she transforms.

You can use her to form a chokepoint in the right side of the map, having her tank and deal damage while the rest of your team helps out.
