I have enough in stealth to get the bonus for backstab and the silent forward roll, which allows me to sneak by just about anything, even if I do pop into the light from time to time. But if I just stand there hiding in plain sight I’ll still be detected. Seems perfect.
Archery I feel is definitely the way to go for stealth. I use dual-enchants to beef up my gear mostly with sneak and illusion related skills, maybe a boost to archery damage (though so far no.) I use Bound Bow exclusively so I don’t have to carry armor, and it takes three or four hits to kill most things. Giants and powerful undead can take ten or more, unless I use the beefy Alchemy to power that down (you CAN poison bound bow!)
I’ve spec’d into dual atronachs in Conjuration also, which serves as a great distraction. I usually only need to throw one Ice Atronach down from the shadows to get everything distracted and pick them off one by one. This lets me run around and reposition myself which keeps things interesting. Lets me pause and take in the scenery more! Sometimes I try and sneak in for a backstab if I think the atronachs will live long enough. They’re also great absorbing magic (they light up like a kaleidoscope when hit with lightning attacks!)
Illusion I use mostly when I feel like showing mercy. If I am attacked by a random polar bear or white saber cat for example, I just Pacify and poof, harmless teddy bear and cute kitty kitty! Plus it is always fun to Frenzy, and have a bandit camp all kill each other. I don’t use fear as much, unless I am trying to isolate one specific guy, in which case you frenzy, then fear just the one, and go handle him yourself!
This style gives me much more control over the outcome of fights, as well as who lives and who dies. I just feel more powerful this way, and more magical even than when I went full destruction.
