I've been looking either for a mod that already exists or for someone to make a mod for a good assassin bow that doesn't look out of place, nor is overpowered. I was thinking something similar to Shadowhunt from Oblivion and can be obtained through the Dark Brotherhood questline.
Any help would be much appreciated!

Thanks!

I wish some one would make the http://www.uesp.net/wiki/Morrowind:Bow_of_Shadows. Not only is it lore friendly but it's the perfect assassins bow. Makes you faster and gives you invisibility.

Perferably i would like it to make you invisible only when your bow is drawn and your sneaking / and increase your sprinting speed by 15% - 25%, maybe also increase your weapon speed, but sprint speed would be good enough for me.
