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	Item Icon	Item Background
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. Provide additional enchant options and increase in probability for 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).
