An effortlessly nasty build, using Oakensould Ring to ease up on the process of just getting on with totally legal things.

The build is really for overworld stealth, pvp and brotherhood/thieves guild trickery. Can be totally fine for dungeons, but the goal isn't the meta, it's just to have fun. If you are planning on doing group content though, sub in merciless resolve for piercing mark. Don't forget to actually use concealed weapon if your sustain struggles and you need an off-balance HA pick-me-up.

I also know that the invisibility skill for Nightblade is really strong, but dashing through the shadows with Elusive Mist is just more fun to try and master. Your call though!

Lastly, tri potions are lovely, but if you want to be a slippery monster, try these immovability potions.
