thats a good point.

Thanks. I have decided on using Alchemy now.

I'm not sure which of my build ideas I should do next. Which of these sounds the most like a build you'd want to check out?

The Imperial Raven(the Legion's deadly secret weapon)(mod-based)

The Masked Crusader(a Robin Hood-esque masked figure)

The Ebonheart Assassin(a powerful Dumner assassin)

or, either of these as the first in a Travelers of Skyrim build series:

The Wandering Scholar(a mage travelling across Skyrim to unlock hidden knowledge) 

The Predator(the best hunter of all of Syrim's large beasts)

Masked crusader I think. That sounds cool

Alright, thanks :)

ur welcome

Honestly, I'm not sure how viable it would be to have one skill. If the skill was Restoration, you'd basically be capped at level 17 - with Alteration, at least you could use the Telekinesis/Fast Travel trick to level as much as you wanted.

The Aetherial Crown/Tower Stone could replace lockpicking, and bartering would be unnecessary. Are there any points that one would have to use another skill?

I believe PCOutcast created a build that only used Destruction, can't remember the name.

Aetherial Crown/Tower Stone still only works once a day, it is different than the Shadow/Ritual/Serpent Stone which can be used multiple times with the crown.

I actually think you could get a lot of mileage out of restoration, expecially with the sun spells added by Dawnguard and the Poison Rune added by Dragonborn  both giving you forms of offense while healing spells and wards could form your defense.
