Lyon and Eirika Strategy

Enemy units will not move until a unit is within range

The enemy units in this map will not move until one of your own units is within their danger zone or attacks them.

However, due to the close proximity of enemies with different colors of the weapon triangle covered, baiting them is quite difficult.

Hit and Run tactics or ranged attacks are recommended

Baiting with tanky units on this map may result in a defeat because Eirika, the Lance Cavalier, and Lyon will be able to reach them during when you try to move your unit into any of the nearby spaces.

Therefore, using units with Canto like Reginn or any units with Trace skills like Summer Ashe is recommended as they can attack and then move back to safety.

You can also try baiting either the Red Fáfnir or the Axe Fighter by attacking them with a ranged unit and then having a dancer move them to safety.

Watch out for Eirika and Lyon's Specials!

Eirika has her Special up in the Infernal map, while Lyon has his at Special cooldown 1.

This means that when either of them attack, your units will be taking a lot of damage.

Try as much as possible to defeat both of them in the player phase using melee units.
