SEE WHAT A WEIGHT ACTUALLY DROPS

Load a LootWhisperer config and pick a container. Edit drop weights and watch the real drop share move as you type. Pin the items whose rarity matters and the rest rescale around them. Roll the container open as many times as you like without launching the game.

    Pinning: click a row's pin to lock its drop share to a target %. Pinned rows hold their value; unpinned rows rescale proportionally to fill the remainder. If pinned targets exceed 100%, the overflow is flagged and unpinned items go to zero.

    Load a config above, then select a container to begin.

    Weights become drop percentages you can actually reason about.
  


  
  

    

      FRESH CONFIG DETECTED
      
    

    

      

        Your config is nearly empty — which means every container is already running vanilla loot.
        Nothing is broken. You only need to add a container here when you want to customize it.
      

      

        ⚠ Adding a container replaces its entire vanilla table with yours. Seeding from vanilla
        gives you the full table to tune, so you don't silently delete the ~100+ items that used to drop there.
