The fastest way to do this is to get someone to make a low level character and help you, or to use two accounts at once.
The level 50 loads Teleport Teammember and a few offensive area hacks. Might get a few heals in there too. Don't bother with getting high level attacks or high level heals, none of that is necessary.
The low level needs to hack the Bathary Node. So do you, but I assume you already have it tagged.
I always make a new character, /suicide to log in as a level 1 and then tag the node and a hardline. I'll be level 3. The lower level your lowbie is, the easier the NPC's are to kill. I'll get to that in a second.
The Corruptor spawns every 45 minutes. To skip this, you have to teleport the lowbie around. With every teleport you have a chance to spawn the Corruptor on the lowbie. Shouldn't take more than 10 teleports, which saves you the time waiting for one to spawn.
After spawning, you and the lowbie have to get at a little distance from the Corruptor. Every minute or two minutes it attacks you and takes away 80% of your health (notice its a percentage, not an amount). Need to find the right distance, but that's not too hard to do.
Because you spawned the Corruptor with the lowbie, the NPC's will be 3 levels higher as the lowbie. Yippy, no level 53's! They're easy to kill =) The Corruptor will stay for 45 minutes.
I load area hacks because they have a longer cast timer than the Ballista hacks. If I kill the low level NPC's too quick, I have to get near the Corruptors attack range to loot them. I rather have a longer cast timer so I don't have to walk so much.
Every now and then a random spawn of level 53's will come. You can hyperjump to get rid of those. Or you can try to find the stairs that connect Bathary with Stamos. There are two of these. If you can get the Corruptor to spawn in Bathary, but stay in Stamos then these random spawn won't be bothering you. Make sure you hack the Stamos node on your account and the lowbie one.
To kill the Corruptor you need 340 frags. These can be traded for insecticide at the Fumigator. The Corruptor has 5100 health and doesn't regenerate the health it loses. Each spray of insecticide does 15 damage, regardless of your characters level.
Remember the Corruptor takes away 80% of your health every minute or so. It's therefore best to attack it with the lowbie, so you can heal it up to its max health quick. The level 50 stays just out of its attack range, attacks the few NPC's that come with the Corruptor. I think it stops spawning those if you don't loot the corpses, but I am not sure. Been too long since I did this. They're easy to kill anyway.
All of this takes a little while to get used to. Once you farmed your first stack of frags you'll get the hang of it. It's all too easy. Just extremely time consuming, especially when you're going for the Headgear. Good luck. :)
