This is a Replacement for the Ebony Mail from the quest Boethiah's Calling.

Does not have sense, Boethiah tells you to kill everybody on Knifepoint Ridge as an Assasin, and the Ebony Mail is a Heavy Armor, and the Boethiah's Enchantment is for an Assasin, so my mod aims to resolve this problem by Replacing by a Ring of Shadows, it does the same thing as the Ebony Mail and you can use with any kind of armor you want to.

Poison damage doubled now is 10.

If you didn't do the Quest then is just, well do the Quest.

If you doing the quest you need restart from the point that you kill all Boethiah's Cultists (STAGE 15), just load a old save from that point.

If you already did the quest, you can get the Ring Of Shadows by typing in the console: 

help "Ring of Shadows" 

then

player.additem XX000D63

All the texts referent to the Ebony Mail was Replaced by Ring of Shadows.

The Boethiah's Champion Outfit was changed to Glass Armor and added the Ring of Shadows.

Also Available at Bethesda.net for PC and XBOX ONE.

Thanks to Sundance at Bethesda Forums for help me fix some issues.
