Last Epoch Building is a free build planner and DPS calculator for Last Epoch. Its Windows desktop application works offline, and a separate Weaver Tree planner runs in a browser. Players can plan passive trees for every class and mastery, and skill trees for every skill with full node support. The calculator models damage for hits, triggered skills, minions, conversion, and ailments, as well as defenses including armor, dodge, block, ward, resistances, and endurance. Equipment planning covers crafting, uniques, legendaries, set items, idols, and blessings. Characters can be imported from save files, Maxroll, or Last Epoch Tools planner links. Builds can be shared using short links or offline codes, and Markdown notes include a live preview. The maker says the project has no accounts, advertising, or analytics. It is verified compatible with Last Epoch 1.4.7, with limited support for 1.2 and 1.3 builds. The maker cautions that the planner is a model and the game takes precedence if results differ. The Windows app can run on Linux through Wine, but that option is community-tested and not officially supported.
