I really appreciate you sentiment. But, in the end it is still only one single perk that you can level up with. Now at a character level of 20 and a sneak skill of 40 I still can't sneak up on someone with a backstab or a cut to the throat. Even if I strip my character naked they still hear me coming. That's not fun. That's depressing. Yes, I'll sneak with my bow and sometimes get a one-shot kill, but that is if the NPC is at the right distance away. I can't even kill Ancano with that --at the current level I am. More often than not I have to open up the console and type a "killall." That idiotic Magnus staff always looses in charge, sometimes before I can even get to Ancano. I just have no interest in learning enchantments, no interest in conjuration, alchemy, or alteration. Just like with Dawnguard I have no interest whatsoever in playing as a Vampire. It just doesn't fit my Dragonborn Amazon-Nord. Still, I really appreciate the time you took to help me out.
You get more than one perk point per level. Let me give you this scenario.
Assuming you start out a
level 1, focusing only on leveling your
stealth skill (without using any cheats or presetting your skill levels) doing it naturally, by the time you hit
level 7, with a
Sneak Skill at about 40, you'll be given
6 perk points, the which could be allocated like http://skyrimcalculator.com/80033.
. So you can understand my confusion when you say "
in the end it is still only one single perk that you can level up with". By character level 20, your skill trees should look something like http://skyrimcalculator.com/80033.
Would you mind clarifying what you meant so that I might better offer you aid?
The Magnus Staff, with use, will deplete. If you gather Soul Gems filled with a soul (and not empty) you will be able to replenish that staff on your own without needing to learn anything related to the Enchant Skill. I'm not sure how it's done on the PC, but you open your weapons inventory and click (i think the shout button), if you have filled Soul Gems in your inventory, a small menu will pop up allowing you to pick which gem to use. Different sized gems (petty, lesser, common, greater, etc) will yield a different amount of replenishment on that item.
