Math:

How many nerves needed to make the two items here are 5, so that means you need 250 gold coins. 16 hearts will be lost if you don't use healing potions when you have the Electrocuted Debuff. You need 7 Tissue Samples to make the two items, so you only need to defeat the Brain of Cthulhu once. That's it. I was just saying. It's not really math, it's just some things I figured out.
