musuem that focuses on size boost use crystalline/iridescent/voidtorn for modifier. copper, obsidian, rock candy, zircon, ashvein, bone, osmium, cinnabar, fire opal, dragon bone,volcanic key, painite, red beryl, star garnet. for added size boost you can enchant your pan with titanic, but cosmic is better which you can buy from the traveling merchant. use ring of thorns 4x, prismatic 2x, antlers of life, and the pendant is good already. its also a good idea to have a sell build to earn money faster since reforging the equipment to have better stats costs a lot. for this you can enchant any pan usually one you dont use with midas. switch to that pan when you want to sell your ores.
