The Forge Calculator is a lightweight but highly accurate calculator designed specifically for The Forge Roblox game.
Forging in The Forge involves multiple hidden probability rules, ore thresholds, and trait activation mechanics. Without clear numbers, players often rely on guesswork — wasting rare ores and missing desired weapon or armor types.
This tool solves that problem by showing you exact probabilities and outcomes before you forge.
You simply select forging mode (weapon or armor), add your ore combination, and instantly see:

• Which equipment types are possible
• Their probability distribution
• Estimated stats and trait activation
  No login, no setup, no distractions — just clear, accurate results.
