So, like it says in the title, this makes normally unusable spells, abilities and effects usable!

In this list, which you CAN chose to download if you prefer, I will show all of the different things and give a brief description. This took me a long time to put together so any feedback would be nice.

To add a spell open up the console " ` " or " ~ " and type the chosen command.

The text file can be dropped into the Skyrim DATA folder and used as " bat UnplayableSpellsAdd " but this will add ALL of the spells, powers and effects, so be careful (which is why I also made a remove file to be used in the same way " bat UnplayableSpellsRemove ").

UPDATE: Added a few new spells and separated the downloads.
