Video game development system

I am involved in developing a 2d sprite game. We are looking to implement a system where items dropped can have a chance to have a title(previous to item name) and surname(after the item name). Each title and surname has a chance to happen on items. For example the title "Powerful" has a 2% chance to happen. Each title and surname alters the stats of the item in some way. Server is C#, client is Javascript(With phaser)
