Influence

Overview

Influence is the currency of City of Heroes, and is given to a character for completing missions, defeating villains, selling Enhancements, etc. It's name comes from the fact that your influence on the citizens of Paragon City makes you more popular, earning you Influence points.
Influence can be used to buy Inspirations, Enhancements, change costumes, and can be traded to other heroes. Influence, however, does not equal Infamy (villain currency), which is in fact the oppisite, and therefor cannot be traded between heroes and villains, even in Pocket D.
