You should know that in Fire Emblem Heroes, the "Refinery" is a weapon enhancement feature that maximizes a weapon's stats and infuses it with new effects to deal increased damage.

The Weapon Refinery can be unlocked after reaching a specific point in the story and is found in the Ally Growth menu. Here's a guide to help you through this process:

How to Upgrade Weapons in Fire Emblem Heroes

Accessing the Weapon Refinery

To access the Weapon Refinery feature in Fire Emblem Heroes, players must complete Book 1’s The Rite of Blades Intermission. This becomes available after clearing Chapter 13 and its subsequent Intermission, A Power Awakens. The Weapon Refinery can be found within the Ally Growth menu under the Merge Allies tab.   

Upgrading Weapons

To refine a weapon, it must be eligible for enhancement. Upgrading a weapon requires a specific amount of Skill Points (SP), Refining Stones, and Arena Medals. For Unique Weapons, Divine Dew is also necessary. Enhancing a weapon can either increase its base stats or grant it a special effect. Upgraded weapons are visually indicated by a unique aura.

Important Considerations

Weapon Types: Different weapon types may benefit more from specific stat boosts.

Resource Management: Refining weapons consumes significant resources, so prioritize carefully.

Event Utilization: Take advantage of events offering increased rewards for refinement materials.

Strategy: Consider the overall impact of weapon refinements on team composition.

By strategically upgrading weapons, players can significantly improve their units' combat capabilities and overall in-game performance.
