Base Game - World Drop

Borderlands 2 World Drops are items that drop from any suitable Loot Source in addition to their dedicated sources.
There are 67 unique items in the World Drop pool, so for farming 1 of the 41 weapons it's best to seek out its dedicated Loot Source.
If you still want to test your luck, you should equip a Vault Hunter's Relic to indirectly increase your chance of a World Drop Legendary.

Suitable Loot Sources:

  • Best Boss Farms: Uranus, Cassius Leclemaine, Haderax
  • Best Chest Farm: Loot-Train after killing Tinder Snowflake
  • All Enemies:
    Bosses, Badass Enemies, Generic Enemies, …
