Hello there

Here you go, my favourite model of  bow - Karliah bow - is now obtainable. Fully enchantable and added to tempering list also ( needs 1 ebony ingot). Actually bow uses full perk benefits. Thats mean, if you have ebony smithing perk that you will be tempering this bow 2 times better than normal.

How to get it?
Check tribute chest in Thieves Guild. 

If you are not a master of Thieves Guild yet, do not worry. Just  use console to obtain this : player.additem 000deed8 1

Installation:
Unpack Karliahbow plugin to data folder. 

Skyrim SE fully working !

Have a nice game:)
