About
This build is only here as a place holder for future ideas, the newest season has nerfed the ability for your bird to drop Acid Flasks to 10% - effectively making the build no where near as good as it was at a 100%.
********
This build is the Falconer Poison Bomber in Last Epoch, centered around Acid Flask and Falconer synergies. It’s a high-corruption setup that combines flask-throwing with poison stacking and bird-based bombing. The core idea is to overwhelm enemies with damage-over-time poison procs while sustaining mana and layering defensive passives. This build is capable over clearing 800+ corruption.
The Endgame Loot filter can be found here.
