It is a shame Bethesda didnt add Bound Dagger to Skyrim, very useful for assassins and it is just a novice spell but you need to travel to Solstheim to get it which can be a bit difficult if you are low level. Now you can buy it from Phinis Gestor in Mage's College.

Note-20.000 gold seen on screenshot is not included in this mod, I use another mod to increase gold for vendors.

Requirements:

Skyrim 1.9
Dragonborn

Installation:

Copy ConvenientBoundDagger.esp to your Skyrim/Data directory.

Uninstallation:

Delete ConvenientBoundDagger.esp
