[Help]Item used for drop calculation

[Access]

Im hoping someone here can help me out..

I recently checked out a private server in which, when you started a new character you had this item called "Deck"

 

Well, to use this item, you simply had a mob targeted and right clicked on the deck, and an html window opened up telling you everything that mob dropped.. the percent it dropped, and the same for spoiling.

 

Iv searched the forums for help on obtaining what I need to make this apart of my server. It was very helpful in playing... Does anyone know where I could get something like this? Its not like the AIO item.. with the global gk, gm shop ect ect.. it was just the drop/spoil.

 

Any help would be great.

 

**Edit**

This would be for an Epilogue server
