Ok, I always play a Stealthy Assassin based character, I have used Illusion & Conjuration as an Assassin and I've also made Assassins using a bow and other kinds of stuff etc. I'm not sure what I could make next although I do love stealthy kind of characters.. I am a Nord right now level 1. Any suggestions?

An Acrobat - "Acrobat is a polite euphemism for agile burglars and second-story men. These thieves avoid detection by stealth, and rely on mobility and cunning to avoid capture."

An Agent - "Agents are operatives skilled in deception and avoidance, but trained in self-defense and the use of deadly force. Self-reliant and independent, agents devote themselves to personal goals, or to various patrons or causes."

A Nightblade - "Nightblades are spellcasters who use their magics to enhance mobility, concealment, and stealthy close combat. They have a sinister reputation, since many nightblades are thieves, enforcers, assassins, or covert agents."

A Witchhunter - "Witchhunters are dedicated to rooting out and destroying the perverted practices of dark cults and profane sorcery. They train for martial, magical, and stealthy war against vampires, witches, warlocks, and necromancers."

Or try what I am trying to do now - a Khajiit Monk! Fists of fury, and sneak uppercuts

Depends. Do you want more of the same, or do you want to try a very different play style?

The opposite of sneaky archers would be a two handed, heavy armed brute. That might seem dull to you. But with smithing, Blocking and a bit of enchanting thrown in you can create a monster.

Well I do love sneaking and the whole play style, but I do really want to stick at this Sneak play style, but what could give it a tweak?... Is it possible to wear heady armor and do so? Or is there anything new I could try like a Battle Axe or anything?...
