What to know

  • The Legendary Vending Machine is unlocked through the "Vend of the Line" side quest involving multiple vending machines.
  • It exclusively sells legendary firearms and equipment, making it a valuable resource.
  • The quest requires inputting codes from five different vending machines by buying and selling items in specific sequences.
  • Some of the best legendary weapons in Borderlands 4 include the Hot Slugger, Complex Root, Kickballer, and Onslaught, often obtained from bosses or vending machines.

In Borderlands 4, legendary weapons are highly sought due to their unique effects and powerful capabilities. The Legendary Vending Machine is a rare in-game feature that sells these top-tier weapons, but to access it, you have to progress through the "Vend of the Line" quest.

The "Vend of the Line" quest begins by interacting with Penelope Streams' drone near a vending machine in Carcadia. As you complete this quest by visiting five vending machines around the map and inputting their codes using item transactions, you will eventually unlock the Legendary Vending Machine located in the northeast side of the Dusty Dangler area.

This vending machine exclusively offers legendary guns and equipment daily, providing a renewable way to acquire top weapons.

What “best” depends on

Which weapon is best for you depends on:

  • Your Vault Hunter’s build (crit/elemental/close-range/mid-range/crowd control)
  • Whether you have gear or skills that amplify certain perks (e.g. ammo regen, kill-based effects, elemental synergies)
  • The enemies you face: if many resistances, having elemental flexibility is helpful; if bosses, burst damage matters; if crowds, splash and on-kill effects are more valuable.

Legendary vending machine wrap up

The Legendary Vending Machine via Vend of the Line is a great chance to secure a top-tier weapon for almost no cost. Among the offerings, Rainbow Vomit and Hellwalker are standout picks for most players. But if your build favours long fights, crits, or a specific style, Lucian’s Flank or Hot Slugger may serve better.
