After finding all routes to Nohr blocked, you attempt to go through Wolfskin Peak, but must battle your way out.

Preparations Before the Battle

An important event will happen after this battle. You can change the course of events, but you will have to do so in your castle before starting this battle. If Corrin has support rank C or B with Kaze before you start this battle, Kaze will die at the end and you will never be able to get him back. If Corrin has support rank A or S with Kaze before you start this battle, Kaze will survive.

To increase support rank with Kaze before this battle, you can invite him to your Private Quarters, or use a Seed of Trust with him. In addition, if there are any side battles available, then during those battles you can increase your support points with Kaze by doing a Pair Up with him or just by standing adjacent to him to perform attacks on the enemy together. If somehow you have reclassed Corrin to be able to use a Staff, you can also heal Kaze to increase support points with him.

Once you have done enough of these things, it will trigger a Support conversation with Kaze, which will increase your support rank with him.

Flying units will help a lot in this battle because they will not be hampered by the terrain. However, the boss unit is strong against flying and mounted units, so keep that in mind.

Rout the Enemy

Your objective is to defeat all of the enemies. Many of the enemies here will drop items upon defeat.

There are several Dragon Veins in the map that will lower the stats of enemies units throughout the map for several turns.

All the enemies here are melee fighters that can't do ranged attacks, so you will not take damage if you attack at range.

Keaton is the boss unit, and he has the Beastbane skill, which makes him dangerous to your flying or mounted units.

After a while, reinforcements will come out of the forts.
