Modules
From PSP2i Wiki
Modules are items that can be equipped onto the player's shield-weave to provide the player with benefits such as stats, resistance to specific aliments, or access to their Blast Types. Shield-weaves can have from 2 to 4 slots for modules, dependent on its rank. Modules can only be equipped to Shield-weaves that has a rank higher or equal to the rank of the module. A module can be equipped to multiple shield-weaves at once, and each shield-weave can equip multiple modules of the same name. Each shield-weave also has its own module configurations, which allows a player to swap between different sets of abilities by equipping each shield-weave with different modules.
