What Last Epoch Planner is

Last Epoch Planner is a free, open-source planner for creating and reviewing builds for Last Epoch. It lets players map the passive tree, choose up to five skills, and allocate points in each skill’s tree. Items can be imported, crafted, and adjusted across Rare, Exalted, Unique, Legendary, Set, and Idol types. The planner also tracks stats and calculates values such as DPS for several skills, chances to inflict ailments, and debuff effects. Players can share builds through planner URLs, and the changelog documents online importing through the Last Epoch Tools API. The desktop application can import offline characters and builds from the Last Epoch Tools planner; the browser version cannot import offline characters. The web planner runs without installing the desktop application, and the site says it works in current Chrome, Firefox, and Safari browsers on multiple platforms. Desktop availability includes Windows, while Linux use is through Wine. The project is MIT-licensed and offers its Discord server for support and discussion. Its calculations have important caveats: the README says many stats and affixes may not work correctly, and a recognized modifier is not necessarily calculated as expected. It is a third-party program, and Eleventh Hour Games disclaims responsibility for problems it causes in-game.

Who it suits

It suits Last Epoch players who want to plan passive and skill trees, work with item builds, or share a planner URL. Desktop users who need offline character importing should use the desktop planner; the browser version does not provide that import option.

What to know first

Limits
