I'm in dire need of a new build. I want an assassin class, but I do not want to use a bow. I want to sneak in, use a dagger or two to instantly kill my target, and get out without amusing any attention.

How do guarantee am instant kill? I don't wanna alert them cause I fail to kill them ASAP, I want to kill'em and get the hell out

Joining the dark brotherhood is a must. Using smithing helps a lot. And naturally, going for the sneak-perks that add damage.

Not sure I understand the question...

Raise 1H
Raise Sneak

Get the assasin perk of the sneak tree (50 sneak needed) and the dark brotherhood armor gloves, one dagger, and profit! instant classic dagger assasin. And the muffle effect on the DB boots helps too.

Never played an assassin, was confused, needed advice, what's best race￥

Race doesn't matter at all.
