Where can you find chopper bug i need it for mehcadino help anyone

Start at Handal at the beginning of the desert, and go 6 steps to the right, and then go 1 step up. You’ll be at a grassy spot right by 2 mountains and right at the edge of the wasteland. That’s where you can find it. 

Thank you so much for telling me where to find chopper bug

Talanca you find it west of the Cave of Ages. The Cave of Ages is located southwest of Camp Ergan
