Open **Events → Crystal Mine**. Crystal Mine Level 1 and Level 2 have different targets and reward tables.

### 🎁 Fragment farming: 2025 Boss

***

Open Events → Crystal Mine and look for the 2025 Boss.

Its reward table includes a box containing 1,200 \[2025] Fragment Boxes, plus 2025 Boss Essence. Open the reward box first, then open the Fragment Boxes to receive usable fragments.

These materials support equipment progression and various crafting recipes.

Other bosses in Crystal Mine have different reward tables. Pick your target according to what you need: fragments, a particular fashion box, or another material.

{% hint style="info" %}
**💡 Tip:** Keep three things separate when planning your farming: the boss reward box, the materials inside it, and the final item you intend to upgrade or craft.
