Several things here:

• Synthesis configurations should all remain together. This should go bellow the existing ones.
• They should all follow the same naming convention. This should all start with CRAFT_
• I think this is absolutely overkill. Current configurations are there because once upon a time, the system worked with different caps and different rates (era vs modern). HQ rates have never changed, I dont think EVERY single number needs a configuration.

I would limit it to a single HQ chance multiplier. That would seem more reasonable.

Refactored into a single setting that is an additional multiplier applied to chanceHQ.
