GrimTools
What it is
GrimTools is a free website for creating and sharing builds for Grim Dawn. Its calculator displays attributes, combat statistics, resistances, and equipment details, then lets users import, edit, upload, and share builds through links. Character save files can be loaded for further editing. Equipment slots support items, prefixes, suffixes, components, and augments, with combined item statistics shown. The calculator offers Base Game and mod options, including Diablo 3 Classes and Reign Of Terror. GrimTools also includes a fan-created item database for searching game items and affixes, plus a skill tree planner. An offline desktop version provides the online functionality and adds build-list management. The site works in modern browsers, while Internet Explorer versions below 11 are unsupported. Save uploads do not support character saves from mods. GrimTools notes that dual-wield ranged attacks-per-second values are higher than in game because the calculator uses a different formula. Users can discuss questions, suggestions, and bug reports through the forum or Discord.
