Tips
Development materials feed multiple systems (module EXP, cartridge EXP, Arc EXP, dye applications). Check which system is your current bottleneck before converting one bucket into another.
Expansion Core is stocked on the Hunter Exchange, so an extra copy is always a Fons purchase away when you fall short.
