Vend of the Line is a scavenger-hunt side mission in Carcadia (Ruined Sumplands, Carcadia Burn) that culminates in a one-shot legendary vending machine. The mission is not replayable on the same character, and the All Things Vend trophy/achievement is missable if you buy too early at the end. Below is a concise path through every puzzle and the precise sequence that makes the trophy pop.

Prerequisites, missables, and co‑op caveats

  • Availability: Vend of the Line appears after progressing Carcadia; players report it after Siege and Destroy.
  • Missable: The mission cannot be replayed on that character. If you miss the trophy, you must do it on a new playthrough/character or join someone who hasn’t finished it.
  • Co‑op: Only one player can purchase a legendary from the final machine. To avoid bugs, have teammates avoid interacting with the machine during the final steps.

How to start

In Carcadia City, talk to Penelope Streams by the lone vending machine on the south side of the main street. Examine the back of the machine to reveal the first code, then interact with the machine to perform the sequence. When you complete each machine, the next location becomes available.

All puzzle solutions (locations, codes, and actions)

# Location Code shown Do this Notes
1 Carcadia (street machine) Green, Green, Blue, Blue (crossed out) Sell in this exact order Use the Sell tab and do it manually; Buy Back is available after.
2 South of Carcadia (rooftop machine) Green, Purple, Blue, Green (not crossed) Sell any items, then Buy Back in the shown order Restore power nearby if the machine is offline. This step requires Buy Back in the exact order.
3 Crumblehall (Grindstone of the Worthy) Purple, Purple, Orange, Orange Tell the trapped Vault Gatherer the sequence The machine is toppled; arrows point “up” to a vantage where you read the code. You don’t need to provide items here.
4 Embracer’s Bluff (Lopside) Green, Purple, Blue, Purple (crossed out) Sell in this exact order Break the wooden plank to crawl behind and read the code. Any choice (melee the customer or trigger defenses) still progresses the mission.
5 The Dusty Dangler (east of Carcadia) Green, Blue, Purple, Orange (crossed out) Sell in this exact order Clear Rippers. If you lack a Legendary (Orange), come back later; you can Buy Back afterward. A powered cable leads to a hidden cave.

Unlock the Legendary Vending Machine (and beat Vend Zane)

Follow the powered cable from The Dusty Dangler down the cliff to a cave. Inside, the Legendary Vending Machine animates as a mini‑boss (Vend Zane). Defeat it to revert it into a vendor with special rules.

  • Damage types: Corrosive or Cryo work well against its armor.
  • Stock and pricing: It only stocks Legendary weapons for $1 each. It cycles inventory on a timer like normal vending machines; if you don’t like the current items, wait without buying or reload before purchasing. Once you buy a single item, it shuts down permanently.

All Things Vend trophy/achievement — do this exact sequence

This is the missable part. After defeating Vend Zane, do not buy a legendary yet.

  • Find the wooden board where the machine originally sat. It shows “Green, Green, Green, Orange.”
  • Interact with the vendor and sell three Green items (one at a time), then purchase one Orange (Legendary) item for $1.
  • When done correctly, the machine “dies” and drops an item called Picture of Zane and Levaine.
  • Pick up the picture and deliver it to Zane at Moxxi’s Bottoms Up in Carcadia to complete the objective and pop the trophy/achievement.

Tips to avoid failures and bugs:

  • Look at the wooden board before selling. Skipping this can prevent the picture from spawning.
  • Don’t back out of the vending UI mid‑sequence. If the picture fails to appear, save to main menu and reload before leaving the area.
  • Bring at least three spare Greens to the cave so you don’t have to strip equipped gear.
  • In co‑op, have only the player going for the achievement interact with the machine. Teammates browsing at the same time has caused failures for some players.

If you missed it or the area locked after buying

  • New character/new playthrough: After finishing the story, you can start a new character at a higher baseline level and rush Vend of the Line again.
  • Shared bank: The bank is account‑wide, so you can transfer a Legendary and spare Greens to your new character ahead of the final step.
  • Join a friend: If a friend hasn’t completed the quest, join their session and perform the final steps there.

Quick reference — what to bring and when

Step Items to have on you Action
Puzzle 1 2× Green, 2× Blue Sell G → G → B → B
Puzzle 2 1× Green, 1× Purple, 1× Blue, 1× Green Sell anything, then Buy Back G → P → B → G
Puzzle 3 None Read code; NPC enters it
Puzzle 4 1× Green, 1× Purple, 1× Blue, 1× Purple Sell G → P → B → P
Puzzle 5 1× Green, 1× Blue, 1× Purple, 1× Orange Sell G → B → P → O (opens the cave)
Trophy step 3× Green; 1× Orange available in vendor stock Sell G → G → G, then buy 1× Orange; pick up the photo; deliver to Zane

That’s the full run. The mission’s charm is in the vending‑machine riddles, but the trophy hinges on that final sequence. Take your time at the legendary machine, follow the three‑greens‑then‑buy rule, and hand the photo to Zane before leaving.
