Forge Master Strategy Optimizer

A browser-only helper for Forge Master players who want to decide whether a newly rolled item, mount, or pet is worth keeping.

Instead of guessing from raw percentages, enter your current build and the app shows how each roll affects the things you care about most:

calculated DPS
single-hit and crit-hit damage
estimated Regen from health regen and lifesteal
marginal value of max-roll effects at your current stat totals
weakest current sacrifice candidates
DPS/Regen change if a new roll replaces an existing piece

For the game rules, stat caps, formulas, assumptions, and known limitations used by this app, see GAME.md.

How to use it

Open the page.
Enter your current item, mount, pet, and skill base stats/effects.
Choose your combat style: Melee, Ranged, or Skill.
Choose a strategy profile:
- Lifesteal: DPS plus lifesteal-oriented comparisons.
- Regen: health plus health-regen-oriented comparisons.
Check the summary cards for DPS, hit damage, crit damage, and Regen.
Use New item comparison when you roll a new piece:
- choose what it would replace,
- enter the new roll's value and effects,
- compare DPS and Regen changes before swapping.
- press Swap to exchange the new roll with the current target; pressing Swap again exchanges them back.
Use Best sacrifice candidates as a quick shortlist of low-value pieces.

When comparing a new pet, choose Pet; the app automatically compares against your currently weakest pet.

Save slots

All data stays in your browser through localStorage. Nothing is uploaded.

You can:

keep multiple named save slots,
save the current build,
load an existing slot,
delete a slot,
rely on automatic draft saving while editing.

Import and export

The Import / Export panel is collapsed by default. Expand it when you want to back up or share a build.

Supported actions:

Generate JSON in the text box and copy it.
Download the current build as a .json file.
Import by pasting JSON into the text box.
Import by uploading a .json file.

Imports accept both the app's wrapped export format and the raw build object. Imported builds are normalized, rendered immediately, and autosaved as the current draft.

Running locally

Open index.html in a browser.

No build step is required.
