Theforgecalculator

The Forge Calculator is a free, fan-made toolkit for the Roblox game The Forge that helps players preview and plan crafting outcomes before spending in-game resources. It simulates different ore combinations and calculates probabilities for weapon and armor outcomes, shows composition and trait impacts, and provides estimated damage and survivability ranges for Worlds 1–4. The site also links to a broader Forge Wiki Hub and other companion tools (Inventory Optimizer, Reroll Calculator, Forge Setups) so players can research raw data and finalize builds.

Results are estimates derived from in-game mechanics and are presented to inform player decisions — they are not guaranteed in actual gameplay. The project is community-maintained and includes an update log to track data syncs and changes.
