Farming red orbs on Lucia's disk

[Coq_Pwner]

I know about Dante, got 700k red orbs on my first try, but I just can't do it on Lucia's disk with Trish. The bats keep spawning in weird places and I either get hit or the combo dies because I was firing at a wall for 5 seconds.

Is there a trick to do this with her? Everyone online seems to still recommend doing this with Trish on Lucia's disk, but it just doesn't seem to work for me, any alternatives? I just need enough orbs to get the Max arsenals achievement, so prolly around 100k. I'm considering just farming the last boss, he's piss easy and the boss bonus should net me the 100k in about half an hour I'd say.

Just as you say, there's no reliable way to farm red orbs wth Lucia like Dante. The best way to get orbs with Lucia is farming either her last or first mission. Lucia's last mission gives you around 1k more orbs than the first one (if you at least get a B), but considering all the cinematics you need to skip and that both bosses are just horrible, I focused on getting an S on her first mission (which is really easy) and gives you around 6-7k every time. Keep in mind that you only need to upgrade one of her swords and that the only arsenal worth upgrading with Lucia are her Daggers (not even the grenades) so just farm enough orbs to purchase everything at once to unlock the achievement and then purchase her Health and DT upgrades, you're gonna need them.

Yeah, I just need the achievement really, played through her hard disk with Trish and it was a cakewalk, not really planning to do DMD, but if I do, I'd use Trish for everything but the stupid fish boss anyway.

Well, thanks for the input!

mission 9, kill the boss regardless of rank, 5k in a few minutes
ain't the most profitable, but the fastest

If you're going to farm the last mission, the first thing you want to do is pickup the Green Orbs around the arena at full health, as Green Orbs are worth 500 Red Orbs.
Still I wouldn't dare using this mission to farm as it has two lengthy boss battles. Unless you're using infinite DT with Trish and spamming Air Raid, do literally anything else.
