Summary

GrimTools is a free website for creating and sharing character builds for Grim Dawn. Its build calculator covers attributes, combat statistics, and resistances, and lets users import and share builds. A completed build can be uploaded to produce a shareable link, while a character save file can be loaded for further editing. Equipment selection includes items, prefixes, suffixes, components, and augments, with combined item statistics displayed. The calculator offers Base Game and mod options, including Diablo 3 Classes and Reign Of Terror. GrimTools also provides an item database for searching game items and affixes, plus a skill tree planner. Its offline desktop version includes the online functionality as well as build-list management. The calculator works in modern browsers, but the save-upload feature does not support character saves from mods. GrimTools notes that its dual-wield ranged attacks-per-second values are higher than in-game values because it uses a different formula. An option to remove ads is shown on the calculator page.
