Forging / Elements
This feature allows equipment forging, awakening, unlocking, repairing, dismantling, and evolution.

【Forging】
By constructing the Forge, you will be able to perform forging.
Leveling up increases the number of forging slots and reduces the number of Fuel Crystals required for actions such as equipment awakening.
【Refinement】
By inserting Elements, you can refine equipment.
The equipment produced and the success rate of refinement will vary depending on the rarity and quantity of Elements used.

By selecting an empty item slot, you can choose the rarity of the Elements.

You can shorten the refinement time by using Fuel Crystals.
Using 10 Elements guarantees equipment of the same rarity as the Elements used.
Using 20 Elements may result in a Great Success.
In case of a Great Success, equipment of one rarity higher than the Elements used will be produced (there is no rarity higher than Legend).
If refinement fails, no equipment is obtained, and you will receive Element Fragments.
Regardless of the number of Elements used, one Element Fragment is obtained per failed attempt.
The attribute does not matter; you will receive fragments of the same rarity as the Elements used.

【Fragment Refinement】
Fragment refinement uses the same forging slots as Element refinement.
By using 10 Element Fragments, you can refine Weapon Crystals, which are used for equipment limit breaks and evolution.
【Equipment Evolution】
If you possess equipment that can be evolved, the blacksmith will notify you via a speech bubble in the forging screen.
Evolution requires Weapon Crystals and items that become available from Wave 3 onward.
【Equipment List】
You can check equipment parameters and perform awakening, unlocking, repairing, and dismantling.
If a hero equipped with the item is currently marching, awakening, unlocking, repairing, and dismantling cannot be performed.

〈Awaken〉 You can awaken equipment by selecting the same equipment with the same awakening rate. Awakening increases equipment parameters. Awakening requires Elements of the corresponding rarity and Fuel Crystals.
〈Unlock〉 You can unlock equipment using Fuel Crystals. Unlocking enables the equipment’s skill. To activate the skill, the hero must equip a full set of equipment of the same rank or attribute.
〈Repair〉 You can restore the durability of owned equipment. Repair requires Elements of the corresponding rarity and Fuel Crystals.
〈Dismantle〉 You can dismantle owned equipment. Dismantling grants Elements.
【Charcoal / Fuel Crystals】

Charcoal can be obtained through Treasure Hunt, and refining it will produce Fuel Crystals.
Fuel Crystals are required for equipment awakening, unlocking, and repair.
They can also be used to shorten refinement time when refining equipment.
Fuel Crystals can be created from the "+" button in the top right. Creating them uses one forging slot.
【Elements】

There are four types of Elements: "Fire," "Wind," "Earth," and "Water," as well as "Iron Ore," each with five rarity levels from Normal to Legend.
They can be obtained through Treasure Hunt or by dismantling equipment,
and are used for equipment refinement, awakening, and repair.
They can also be used to increase Guild levels.
