How to understand armor value

[Cezar]

Thought could be a good idea to standard the equip but you gave me some great advices.
Well if I could afford a fungi I probably whould’nt bother configuring the excel.
I just want a little planning on equip to optimize my low money.
Last advice I ask at this point is: I’m in full crafted atm, could have any sense move to crustacean losing some AC for some str and sta? Thanks everyone
