Grape Juice Voucher/Voucher Redemption NPC

[Marihna]

Hello All! I looked through a lot of the forums and couldn't quite find what I was looking for in a script.

Would I be able to get help with:

-Making a script that will allow all mobs to drop an item at a low rate titled "Grape Juice Voucher". (I understand this would need to go into my itemdatabase -?-) 

-An NPC that will redeem 1 voucher for 1 Grape Juice.

 

This is something that I used to see on a very old server that I played on and really enjoyed the concept. I'm just at a complete loss of how to make it happen, as I am relatively new to scripting. Any help would be greatly appreciated. Please let me know if you have any questions. Thank you!

This request is very simple on the scripting side of it as all a script will do is take/give the appropriate items.

The majority of the work will come from you adding your custom item (voucher) and adding the item to the mob's drop table (mob_db). Once you do this, let us know what your voucher item ID is and we can script the exchange NPC.
