making an item give a title

[Jorin]

Ok so I had an idea where a player would consume a item that grants a title. Problem is I am having zero luck figuring this out. I know i need to create the item to consume and a spell for the click. From there I am lost lol. What needs a scripy, the spell or the item? And would the spell data need to match the script file? And lastly, where would I save said script, global load? Any direction here would be awesome even a basic script i can read over and modify.
