Crafting in Phantasy Star Online 2 allows a character to modify equipment and techniques.

Equipment extensionEdit

Main article: Equipment extension

Equipment extension permanently modifies weapons and units. Equipment extension replaces certain attributes, such as ATK/DEF values and stat requirements, without changing other attributes, such as latent abilities and set bonuses.

Technique customizationEdit

Technique customization creates custom discs. When used, the custom disc will improve one attribute and degrade a different attribute of a technique when used by that character. These modifications remain until another custom disc is used on the same technique.
