GrimTools is a free website for creating and sharing character builds for Grim Dawn. Its calculator covers attributes, combat stats, and resistances, with options to import and share builds. Users can upload a completed build to get a shareable link, or load a character save for further editing. Equipment slots allow selection of items, prefixes, suffixes, components, and augments, with combined item stats 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, along with a skill tree planner. An offline desktop version includes the online version’s functionality plus build-list management. The save-upload feature does not support character saves from mods. GrimTools also notes that its dual-wield ranged attacks-per-second values are higher than in-game values because it uses a different formula. The site works in modern browsers and does not support Internet Explorer versions below 11. It is created by Dammitt and is not affiliated with Crate Entertainment.
