IndustrialCraft More Qualities: Legacy Chance

Requires Factorio 2.1.24 or later.

Keeps the quality upgrade chance curve used by IndustrialCraft More Qualities through version 1.0.5 while using its maintained Factorio 2.1 release.

The original Dynamic chance bonus startup setting and original defaults (20% base chance, в€’0.4 percentage points per tier) are restored. Saved/custom values remain unchanged. The saved base chance and bonus are applied in the original tier order, with the original upper limit of 100%. Normal quality keeps the chance present before IndustrialCraft updates it, including changes made by other mods. Vanilla quality defaults follow the installed Factorio version. Quality names, links and levels remain owned by the maintained mod.

Use this companion when upgrading a factory from version 1.0.5 or earlier. It intentionally changes the maintained mod's constant-chance behavior to the older configured curve. Other factories should use IndustrialCraft More Qualities alone. Version 1.0.6 changed how normal quality participates in the curve; this companion targets the earlier behavior. The setting was removed in version 1.0.8.

The chance curve is applied after the maintained mod generates qualities, before later final-fixes modifiers such as No More Gambling's curve settings. It adds no runtime script.

Original chance behavior by mimic, distributed under the MIT license on the Factorio Mod Portal. This companion independently implements the original arithmetic and tier order; it includes no artwork or runtime code from the original mod.

Bounds extreme configured multipliers and health scaling at the game’s supported limits. Valid bonuses keep their scaling; quality levels, names and progression stay unchanged.
