1. There are very few dark gold items with lucky bonuses. I have only seen two items with high luck bonuses so far (picture below)
2. Synthesize the purple one (blue is also acceptable), specify the part, specify the lucky attribute, select the embryo with two lucky entries, and refine the third one (picture below)
3. If you have time, you can inlay lucky charms
4. Bring a powerful weapon. It’s easy to brush through this map. The original poster’s weapon is as shown below. It’s an ice type. Basically, you can attack a wave of monsters with one basic attack.
