Following the Complex Modification formula on page 114 of the Ultimate Magic does not equal the listed amount for the mods. Example Construct Armor listed as x but follow the formula given and the price is 11k cheaper when done as a bard or 18500 cheaper when done as Cleric than the listed price.
I understand that its like wondrous item crafting and is more art then science but the difference of cost is fairly huge. I mainly wish to know if its allowed to use the formula given vs the listed price since different casters can cast the requirments at different levels.
I would give more specifics but I do not want to let out anything thats not under the OGL etc.
Thank you,
