Death check with weapon script

Introduction

I am currently working on a project that requires the Player to kill an NPC, and than adds an item upon the death of the NPC. Through much trial and error, I finally ran down how to achieve this. I intend to lay it out here, for those who might want to do something similar.

So, in this tutorial, I will be guiding you in how to do several things:
1. Create a Magic Effect Script that will check for the death of an NPC at the Player's hand, than add an Item to the inventory with a nice little message.
2. Create the item to be added, in this case, the soul of the NPC in the form of a bottled potion.
3. Create a scripted enchantment that runs our script. (Because there is no way to activate a script when the Player hits an NPC).
4. Finally create, and place into Tamriel, the weapon that will execute the script.

There is a rather good Tutorial on the Wiki that got me started on my path in this project, thought I should give it a nod, Deadcount on a weapon.
