Build Notes and Guide Generator

Formula Used

Base hit: flat damage × (1 + percentage damage ÷ 100) × weapon damage percentage.

Estimated hit chance: 85 + (Offensive Ability − enemy Defensive Ability) ÷ 40, limited between 60% and 100%.

Estimated DPS: base hit × attacks per second × hit chance × average critical factor × enemy resistance multiplier.

Enemy resistance sequence: subtract flat reduction, apply reduced-target percentage, then subtract stackable percentage reduction.

Physical test damage: incoming hit after physical resistance minus absorbed armor. This is a planning estimate, not an exact game simulation.

Overall score: 42% damage, 40% defense, and 18% sustain. Every component remains visible in the result.

Frequently Asked Questions

Does this include every Grim Dawn item?

No. This standalone file provides complete planning fields without bundling a copyrighted full item database. You can enter any item manually.

Are the DPS results exact?

No. Grim Dawn combat includes skill formulas, animation timings, armor interactions, proc uptime, and enemy-specific mechanics. The calculator provides transparent estimates.

Can I plan dual-masteries?

Yes. Select both masteries, record mastery-bar investment, and add all active, passive, toggle, modifier, and transmuter skills.

How are resistance penalties handled?

The selected difficulty applies a configurable planning penalty. Effective values, overcaps, and deficits appear in the result table.

Can I plan Devotions?

Yes. Add constellations, costs, affinities, Celestial Powers, bindings, and acquisition order. Point totals are checked automatically.

Does it support pet builds?

Yes. Add permanent, temporary, or player-scaled pets with damage, speed, OA, DA, resistances, and uptime.

Can I compare two builds?

Yes. Save snapshots as Build A and Build B. The comparison tool reports differences in health, OA, DA, armor, DPS, and resistance values.

How are builds saved?

The browser-storage option saves form data locally. JSON export creates a portable backup that can be imported later.

Can I create a PDF?

Use PDF / Print. Your browser can save the printable results and build summary as a PDF file.
