Game developers stated that the long-rumored "Legacy System", which would allow for additional improvements of Level 50 characters, had evolved into the Invention System.
- Main Article: University
Heroes and villains use Invention Salvage and Recipes to create items at Invention Worktables that are located in the newly opened Universities. Supergroups may also install an Invention Worktable in their bases.
Heroes can find campuses in Steel Canyon, Croatoa, and Founders' Falls. Villains can find a campus in Cap au Diable. Both heroes and villains can find a campus in Kallisti Wharf. The Praetorian equivalent, which heroes and villains can also use, is the Cultural Direction and Education Center, in Imperial City. All campuses have many Invention Worktables at which inventions may be created.
A series of tutorial missions for the Invention system can be completed through Admissions Officer Lenk in Steel Canyon's University for Heroes, through Dean John Yu in Cap au Diable's University for villains, or through Relations Expert Verna Arcola in the CDEC for Praetorians. Completing the tutorial awards the Inventor Badge. The character will also receive Salvage and a Recipe to create a Common Invention Enhancement.

- Main Article: Invention Made Costumes
A number of animated costume pieces can be created with the system, including various kinds of wings and special boots.
- Main Article: Invention Temporary Powers
There are a number of temporary powers craftable with the inventions system from recipes. Temporary powers may also be crafted from Empowerment Stations in bases.
There are currently no Inspirations that can be crafted.
- Main Article: Crafted Base Items
As of Issue 13, crafted base items require Invention Salvage to create, rather than components made from base salvage. Base salvage no longer drops, but can be converted into invention salvage via brain storms.
Invention System Badges
Many badges can be earned by crafting.
- Main Article: Memorization Badges
The recipes for crafting common IOs can be memorized. Memorization allows the crafting of enhancements at half the cost and without the need for a recipe. A total of 45 badges are available for memorization, 36 of which are needed for the Field Crafter Accolade and its Portal Workbench accolade power.
