The majority of the materials can be found on missions

Partner Machine Feeding Basics: For this partner machinery to evolve properly you will need to buy martial empires gold purchase, or farm (collect), the correct materials. The majority of the materials can be found on missions, while others (such as technique disks) can be bought.

Here is one of the simplest lists explaing what each type of material will raise or lower. This is not an all inclusive list, as it would take too much space, and need to be changed as new items are added. The star value of an item effects how much it will increase or decrease an area by.

Mates - Raise Stike (allot) and Raise Technic (a little)

Items like monomates, dimates, trimates, moon atomizers, etc. will all raise strike allot and raise tech a little. The ratio isn't a science, but the key thing to keep in mind is that you can increase strike allot with the right type of mates.

Technique Disks - Raise Technic: Purchasing tech discs (such as reverser and resta) will raise the tech stat without altering any other stat, very useful for getting the technic level to the right spot before evolving.

Rods, Wands, Staffs - Raise Technic (allot) and Lower Strike (a little)
