How to use this generator

Build weighted loot entries and export normalized drop chances.

How generation works

Enter the design assumptions for the system you are balancing.
Tool2Do calculates a deterministic table or result from the displayed method.
Use export options only where the output is reusable game data.

Formula

Drop chance = item weight / total weight x 100.

Example

Weights 70, 25, and 5 produce 70%, 25%, and 5% drop chances.

Using the generated output

Use the output as a practical starting point, then review it before using it in an important workflow.

Game engine export

This gaming tool can export the visible result as structured JSON or CSV, plus text-based Unity, Unreal, and Godot snippets. The export is generated in your browser from the current result and is meant as a clean starting point for prototypes, balancing sheets, and engine-side data tables.

Assumptions and limitations

Calculations run locally in your browser.
These are balancing helpers, not universal game design rules.
Do not paste private production telemetry or player data.
