3. New Forge <Primal Force> System

1) Primal Force is a system that allows you to grant additional stats to equipment with Resonance by consuming Magic Stones.

- Primal Force unlocks when your character reaches Level 120.

- When acquiring Rare-grade or higher equipment through various content such as drops, Treasure Chests, and Awakening, there is a certain chance to obtain equipment with Resonance.

- Each equipment can have up to 4 Void Resonance Slots, and equipment with more slots can receive more powerful enhancements through Primal Force.

- Resonance appears across 10 different equipment types: Weapon / Top / Bottom / Gloves / Boots / Necklace / Bracelet / Ring / Earrings / Secondary Weapon.


2) Equipment of Epic grade or higher with Resonance can obtain additional stats through Primal Force.

- Primal Force uses Epic-grade or higher Magic Stones, Dragon Steel, and Darksteel.

- Different types of Magic Stones are required depending on the equipment slot, and the values of the stats obtained vary depending on the grade and tier of the Magic Stones used.

- The stats obtainable through Primal Force consist of Main Stats and Sub Stats. Unlike Main Stats, Sub Stats have a certain chance to appear when performing Primal Force.


3) Equipment with Resonance can use “Infuse” to transfer its Resonance to equipment of one grade higher.

- Infuse uses the equipment to be infused, the material equipment, Divine Anvil, and Copper.

- The success rate of Infuse varies depending on the tier of the equipment providing the Resonance.

- When performing Infuse, all materials except for the equipment that was intended to receive the Resonance will disappear.
