Forge
In Sands of Aura, the Forge is the primary component for enhancing Weapons and Armor Sets. It is situated in the center of the main plaza on Starspire Refuge.
The Forge itself represents a progression system and can be further enhanced throughout the game. A total of five additional tiers can be unlocked, each tier raising the maximum rank a Weapon or Armor Set piece may be upgraded to:
- +1 to +8 - Regular Forge
- +9 to +12 Weapons - Complete the Side Quest The Smile of Hatred on Radix Stronghold
- +9 to +12 Armor - Progress through the Main Story The Embers of Avarice
- +13 to +20 - may be unlocked in arbitrary order by handing in Anvil of Andalux, Snowcinder Bellows and Korvig's Grindstone
Upon locating the Forge, the Side Quest Tending Flames from Danaya, The Forgestoke can be accepted to gain free materials and currency.
Using the Forge costs Glint and Sacrumite upgrade materials.
Weapon Forge
Weapon Forge allows the construction of an entirely new weapon based on its four passive modifiers Fighting Style, Weapon Head, Pommel and Codex. Besides Character Creation, the Weapon Forge is the only avenue that allows choosing a weapon's Fighting Style.
Forging a new weapon costs 200 glint regardless of modifier combinations, adding or omitting optional modifiers does not affect the costs. Weapon Forge allows the choice of all modifier combinations without limitation as long as they have been learned.
Weapon Upgrade
Weapon Upgrade allows enhancement of owned weapons. Raising a weapon's level to higher tiers necessitates upgrading the Forge itself at specific thresholds. During the process, the attributes of the next upgrade tier are displayed.
Upgrading existing weapons costs glint and Sacrumite upgrade materials.
Armor Upgrade
Armor Upgrade allows enhancement of owned individual pieces of armor. Raising an armor's level to higher tiers necessitates upgrading the Forge itself at specific thresholds. During the process, the attributes of the next upgrade tier are displayed, including additional Rune Slots.
Upgrading existing armor costs glint and Sacrumite upgrade materials.
Weapon Modify
Weapon Modify allows changing and swapping out three of the four passive modifiers of an owned weapon, excluding the Fighting Style. The process allows the weapon to be recrafted with any combination of modifiers without limitations and displays the new nomenclature of the weapon.
Modifying a weapon costs glint. The price is based on the rank of the weapon.
