Getting the parts you need in Borderlands 4 should be quick and not a chore. If you want to craft a great weapon or upgrade your kit, you need a plan that cuts the grind. Focus on actions that give both materials and money so you can keep buying what you need. Keep an eye on ways to grow your Borderlands 4 Cash while you farm, because smart spending early makes every run more worth your time.

Boss farming is the fastest way to stack common crafting parts. Pick a few early bosses that drop the items you need, like Splash Zone or the enemies around The Pitted Stain drill site. Use Moxxi’s Big Encore to respawn those bosses fast so you can run tight loops. Defeat the boss, grab the loot, use the machine, and run back. That loop turns slow scavenging into a short, repeatable run that you can time and improve.

Rifts and event spawns give a different kind of payoff. Rifts often have tougher mobs and better loot tables, so they can drop rarer materials you do not see in regular zones. When a Rift opens, prioritize it if you need high-tier parts. Treat Rifts as a high-reward option you add to your farming rotation. They are less predictable than boss loops, so do a few runs and then return to your steady boss route.

Side missions are a steady way to refill supplies and cash. Complete the side quests that give good rewards and currency before you head back into farming. The money you earn from quests can buy consumables, pay for Encore respawns, or let you buy materials from vendors. Side missions also let you explore more of the map without wasting time on weak fights. Use them between boss loops to keep your inventory full and your runs efficient.

Optimize your routes and your gear so each run wastes as little time as possible. Choose weapons that clear your chosen boss area fast and bring movement skills to skip long walks. Set a short path: hit the respawn machine, sprint to the arena, clear the boss, then sell or stash loot quickly. Do not stop for low-return fights during a farming run. Use quick-sell or stash methods so you do not break your rhythm with long inventory screens.

Spend your money with a plan so each run becomes more profitable. Buy items that let you run more loops or make each loop faster. Spend buy Borderlands 4 Cash on ammo, fast travel, or Encore respawns when those costs are low compared to the loot you expect. Save for upgrades that boost clear speed or damage, because those upgrades shorten every future run. Keep a small reserve to buy rare materials from vendors when they appear so you do not miss a chance to finish a craft.

Change your route when it stops paying off. Some bosses get farmed by everyone, or the market for a part gets flooded. Mix boss loops with Rifts and side missions to avoid burnout and to keep profits steady.
