# Item Grade System

{% columns %}
{% column %}

The Grade System upgrades your normal item from Grade D to Grade A. Not all items can be upgraded, only those with a grade effect on description can be upgraded.

Each item grade provides a special effect when player equipped. The chance rate of your upgrade succeeding depends on the refinement level of your item.\
  \
Rest assured that failure during the upgrade process will not result in the destruction of your item, only the materials consumed.

   

**Bonus Probability:** Adding Blessed Etel Dust improves the upgrade success rate by 5% per unit consumed.

### How Item Grading Works

* **Eligible Equipment:** Only specific high-tier items, such as **Level 4 Weapons** and **Level 2 Armors**, can be graded.
* **Progression Tiers:** Grades progress sequentially through **No Grade → D → C → B → A** (with A being the highest).
* **Refinement Reset:** A successful grade-up attempt completely **resets the item's refinement level back to +0**.
* **Preserved Stats:** All existing cards, enchants, and random options remain safely intact during a successful or failed grading process.
* **Requirements & Costs:** Grading requires specific rare materials and Zeny. You can use catalysts like **Blessed Etel Dust** to increase success rates.
