Fortune's Weave Weapon Weaknesses Guide

Fortune's Weave weapon weaknesses give you a simple battle rule: use magic against heavily armoured enemies, arrows against flying foes, and spears against cavalry units. You also need to check attack range before committing because an enemy inside its range may counterattack. This page turns Nintendo's official combat advice into a practical first-pass battle checklist.

Confirmed weakness matchups

These are the official matchups currently supported by the checked source. Do not expand them into an older Fire Emblem weapon triangle or assign exact damage multipliers without in-game evidence.

Check counterattack range

Weakness advantage does not remove the danger of retaliation. Nintendo warns that attacking from inside an enemy's attack range may trigger a counterattack.

Before attacking:

1. Select the unit with the correct weapon or attack type.
2. Check whether the target is inside the enemy's attack range.
3. If the enemy can counter, attack from a safer position when possible.
4. Use a unit with strong defence or evasion when a counterattack is unavoidable.
5. Recheck the map objective after the attack instead of chasing a weakness at any cost.

Use the combat basics guide for positioning and the weapon types guide for the wider evidence boundary.

Build a mixed party

Nintendo recommends bringing a varied group of units rather than relying on one damage type. A practical party check is:

• at least one option for armoured targets;
• an answer to flying enemies when the map includes them;
• a spear user or equivalent answer when mounted units appear;
• a durable or evasive unit for counterattack exposure;
• a route-appropriate support plan from classes, Combat Arts, or Hero-specific abilities.

The exact class and weapon roster is still being documented, so this checklist describes battle roles rather than assigning a permanent best class.
