make sure the first tick of lightning emission does 70 -90% damage to the weakest mob so you can get the electrocution, then the second tick will give you the kill.
When you activate the site make sure to let the melees run to you and die so you can let the ranged mobs take over the point, you want to keep the ranged mobs alive, also the spawns can be slow so run around on the spawn before moving to the next, you can also check the radar but the tanky mobs can confuse you.
For mods you want MP collector for zooming, CDR, skill cost and range, but don't get too much range around 15-17m is the sweet spot or you will be killing those ranged mobs holding the point trying to pick up mana cubes.
put on some weapons you want to level since you will be getting a good amount of exp.
I averaged between 300 - 450 electrocutions and 300 - 350 kills per run/5mins.
The plan is to get the kills from this spot then move to Fortress outskirts for the rest of the Electrocutions shown in this video: th-cam.com/video/MHW7LZTx7gU/w-d-xo.html&ab_channel=manneyd
