Important notes: [ul][li]All drop rates listed here are for Grim Dawn without the expansion. I haven’t parsed the expansion data yet but I know the drop rates will be lower because more items were added to each list.[/li]
[li] All items listed here are blueprints. I removed the "Blueprint: " and "Recipe: " text from every item to save space.[/li]
[li] Blueprints are grouped by drop rate from highest to lowest drop chance and listed in alphabetical order. It’s best to use Ctrl + F to find something specific.[/li]
[li] In my opinion, these drop rates are horrible and these blueprints are so common that almost all of them should be found through normal gameplay (or Treasure Trove farming). Farming these bosses is a waste of time.[/li]
