If any of you played the Thief games and also used the Oblivion mod "Thieves Arsenal", you're probably thinking "When will someone make this for Skyrim?". Well, I have decided to. It's not going to be directly ripped from the Thief series though, some recognizable weapons such as the blackjack will be in it. I'm not sure how long this will take, since I'm fairly new to the Creation Kit it could very well take a year. But by the end of that time, it will be a glorious mod.

Now, the thing I need is the script used in Thieves Arsenal. Thieves Arsenal had a blackjack weapon that essentially killed an enemy when you hit them from behind will unseen, and "resurrected" them a short while later, to simulate a "knocked unconcious" effect. I'm going to need a similar script, that will cause a weapon to kill the target as long as you are not detected by them and hit them from behind, and then resurrect them after a short while. It shouldn't be that hard, but I need someone to give me specific scripts that I should apply to the weapon. Of course, if I'm going to make this mod, I need to learn these things myself, but this one script is crucial to the mod and it would go along so much faster if someone could help me make such a weapon.

I believe a mod like the one you are talking about already exists: http://www.skyrim.nexusmods.com/mods/19447
And welcome to modding, I hope you find other ideas to turn into mods for thieves.

Not quite what I was thinking about. This would be more inspired by the Thief series, that mod only adds some weapons and gameplay features. This would be more like the Thieves Arsenal mod, which would add a trader who buys stolen items from you, gives jobs, and sells blackjacks, water arrows, etcetera. All I need right now is a script for the blackjack.
