Nice to see that people find this kill interesting. Jayden, as it has been already explained, this is a regeneration fit. It doesn’t actually have 1 million effective hit points. It wouldn’t be effective for running through Uedama, it would probably die to 5 or 10 catalysts. Given that Uedama it often camped by 15 to 40 Catalysts, I would say that the Nereus wouldn’t stand a chance.
You would be better off with a Blockade Runner, as other already suggested.
1x T2 Hobgoblin drones do 20.00 HP Thermal.
5 T2 Hobgoblins do 100 damage every 4 seconds. If he had no defenses, 1500 HP damage per minute per orca with full drones out. And that’s without the % of shield. He just needs to tank that.
You could also just fit a ship like that, and assume no boosters/implants/skills/…
Try it out, let us know how those two orcas do a million damage in less than 22,32 minutes. Or instantly like you said but that’s a bit of a stretch.
