I have a level 17 Psion Shaper, who has a suit of armor that is, I believe overpowered. I have followed all of the rules, the armor has not gone over +10 on the pricing table and the rest of it is gold piece enchantments. Is there a limit to how many enchantments you can place on a piece of armor; if they are simple gold piece cost enchantments? When the total pricing goes over 200,000 gold pieces, should I begin to multiply the cost by 10? I am having trouble finding out what to do, this is the complete list of my characters armor.
