Call of Lightning build helped me out a lot when I was starting out.
You need a Deep Drain and a Call of Lightning (CoL) equipped for it to be effective. CoL for close range, and Deep Drain when they are out of range of your sword.
Plus, equip the most powerful teleporter you got and the most powerful electric hook you got, as well. If you got mythical teleporter and hook, that would be great for you can use them twice.
For drone, high energy draining drone is the key. (Triple electric or blue angel)
As for Modules, health, then energy then cooling is your priority order.
I remember watching a CoL build on the Supermechs Youtube Channel but I can’t seem to find it anymore.
