After kissing a lovely certain Daedric artifact goodbye and saving Erandur's hide, I discovered that he was utterly useless to me as a follower -- low-capped combat skills and no magicka with which to actually use any of his own vanilla spells (can forget about giving him new ones via UFO).

So, I tried to fix him.

I duplicated his vanilla class ("Priest") in the Creation Kit and tweaked it, so these changes should not affect any other NPC Priest in the game.

- He will now level with magicka as his primary stat.
- He will still gain health, but it may not be as much.
- He will now how have stunted but reasonable stamina.

His still weights were also tweaked, but more for roleplaying flavor in order to match his back-story:

- Completely removed smithing.
- Lowered speech
- Increase to alchemy
- Conjuration now on par with restoration


Please report any problems you find - this is not fully battle-tested, but I'm using it on my own game and have not found any problems with it.
