I am trying to finish out the heads and skins i am interested in but haven't had luck farming.
I am looking for the following (I assume Special Edition heads are still dupable?)
Siren: Heads- Cold Steel, Kawaii Killer, Shrapnel Slayer, Till Death Do us Part, Special Edition: Clean Shave Skins- All Black
Assassin: Heads- C0al Train, G4I4h4d, Alienation, Unreality, Special Edition: F0rg0tten
Mechromancer: Heads- XXX, Lovely Corpse, Digitized Death, Keeping It real, Metal Blood Skins: All White
Gunzerker Heads- Boatmurderer, Superduperfly, The Baron, Rastfarion, Special Edition: Private Eyes Skins- All white, All Black
Commando: Heads- Shadaloo Stylish, Bone Blinder, Space Knight, Dapper Gent Skins- All white
In return, I can dupe almost any legendary pre-dlc (i maybe missing a few but all 5 of my characters are almost maxed with weapons in backpack and bank), a lot of commonly asked for purples (like allegiance relic, yellow jacket), a lot of seraphs (all the hammerlock DLC plus more), and a lot of common, flavor text, blues (trespasser, evil smasher, etc).
I also have some heads/skins that i duped before using that i can dupe:
Medic Mantis (commando) All white (siren) All Black (Commando, Mechro, Assassin)
I have a couple of those items you are looking for, do you have any other skins for siren to spare?
Unfortunately not. A majority of stuff i have found i get so excited i use before i think to dupe them. The few i listed are the only ones i have farmed and remembered to dupe are the ones listed. Sorry.
