Native C# Grim Dawn Save & Stash Editor with Fangs of Asterkarn (FoA) Support
GrimEdit is a high-performance, native C# save and stash editor for Grim Dawn. Designed from the ground up to support the latest Fangs of Asterkarn (FoA) expansion, Forgotten Gods (FG), Ashes of Malmouth (AoM), and the Base Game.
Unlike older editors, GrimEdit handles modern save block format changes (such as Block 8 Version 8 extra skill bytes, Block 16 Version 12 expansion data, the 10th mastery/Berserker class combos, and new expansion factions) with 100% byte-accurate fidelity and checksum validation.
- Bio & Identity: Rename characters, toggle Hardcore/Softcore mode, change gender.
- Level & Progression: Edit level (1–100) with automatic exact EXP curve calculation.
- Points & Currencies: Adjust Iron Bits, Crucible Tributes, Attribute Points, Skill Points, and Devotion Points.
- Base Attributes: Modify base Physique, Cunning, and Spirit points.
- Class Combo Resolution: Automatically resolves internal game class tags (e.g. Warlord, Spellbinder, Blademaster, Berserker, etc.).
- Skills & Devotions: View and tweak skill levels, devotion levels, and devotion experience.
- Gear Inspection: View equipped items across all slots with base record names, prefixes, suffixes, and components.
- Inventory Sacks: Inspect items stored in bags and character inventory.
- Personal & Shared Stashes: Read and edit personal stash tabs and shared stash files (
transfer.gst/transfer.gsh). - 1-Click Formula Unlocker: Unlock all crafting blueprints in
formulas.gst/formulas.cstwith a single click. - 1-Click Reagents Maxer: Set all rare crafting components (Aether Crystals, Ugdenbloom, Blood of Ch'thon, Ancient Hearts, Tainted Brains, etc.) to 5,000x in
reagents.gst.
- 100% In-Game Accuracy: Mapped against all 24 active factions in the Grim Dawn engine (including FoA factions: Kurn, Noktukari, and Asterkarn Hostiles).
- Batch Modifiers: Quick-action buttons to Max All Friendly Factions (Revered 25,000) or Max All Hostile Factions (Nemesis -20,000).
- Difficulty Unlocks: Instantly unlock Normal, Elite, and Ultimate difficulties, plus Crucible tiers.
- Waypoints & Portals: View and unlock world waypoints.
- Zero Data Loss: Creates timestamped, rolling
.bakbackups in a dedicatedGrimEdit_Backupsdirectory before every write operation. - 1-Click Rollback: Restore any previous backup directly from the UI or CLI.
