User blog comment:Scout608/Which mechanical boss is easiest?/@comment-24410557-20140119181700

Destoryer, it's easy if you make one of those boss arenas using platforms. It's easy without it too, but it helps alot.

Also, when hes health is low, try to finish him off while hes head is above the ground, otherwise it's drops will be burried in blocks underground and it's difficult to find them.
