The grading system is the latest method to further strengthen your gears. When an equipment is graded, it will have distinctive features for the level of grade.

Grade D
Grade C
Grade B
Grade A

Grading serves 4 main purposes:

1. Acquire grade-specific bonuses from an equipment. These bonuses are cumulative.
   • Example: Grade B Thanatos Bow-AD will provide all bonuses described under [Bonus by Grade] for Grades D, C, and B.
2. Acquire grade-specific bonuses from a card. (Future Implementation)
3. Alters enchant tables of Enchantment System. (Future Implementation)
4. Increase stats gained from refine.

Each grade has a certain percentage bonus compared to an ungraded item. Refer to the Refine page for exact values.

Example: Grade B weapon will provide 12 ATK & MATK per refine (8 * 1.50 = 12).
