Build it with the Mecha set mod.
Furthermore, if you lower the armor value with the Seeking Shriken mod, it will be easy to defeat even at high levels.

Throw in Kubrow, which also has the Mecha set mod.

The effect of the Mecha set mod is that it is triggered by attacking enemies with abnormal markers, and when defeated, the markers will go over the wall and cause widespread damage.
[Ash] increases the amount of bleeding damage, so it works well for cutting state abnormalities. Knocking down a marker with a damaging cutting condition attack can kill the surrounding enemies in an instant.

Of course, it is also possible to attack with abnormal conditions other than bleeding damage.
