This is a character build for those with no interest in playing a fair game. You will one shot nearly every enemy in the game. Enemies will also never even attack you, as they won't be aware of your presence.

Again, this is written for those who wish to have an optimized character, one that's as broken as the game allows. To accomplish this my guide is fairly specific as to skill point and perk progression. The build is finished at around 35, and the invisibility assassin's blade core of it is finished much earlier, at around 20. This leaves plenty of room to have an entirely full two-handed or destruction perk tree should you grow tired of one-shotting everything without it even trying to hit you.

The core of this build relies on the illusion spell invisibility and combines it with the assassin's blade perk. These two things are what really break the game and are the first things to obtain. The rest is just gravy, although maxing out enchanting is very important. The build also uses full smithing and heavy armor perks, and enough points in blocking to get elemental damage blocking. These are for the rare times when the invisible back stab combo won't work. These times are extremely rare, really just random dragon encounters and large enemy mobs where the quest forces a companion on you.

A short note on how to use Invisibility and Assassin's blade to kill enemies will be at the end of the guide.

During the opening dragon attack scene choose a high elf race. Any race is fine, really, but the high elf bonuses to illusion and mana allow you to reach optimization about four levels earlier. In the end it matters little. For now save all of your perks and put points in health should you level up. Choose to accompany Hodvar. Play the opening scene as you like. No need to grind yet. Once outside make your way to Riverwood but first stop by the stones along the river to the west of the town. Pick the combat stone. Pay at the inn to sleep for 8 hours and receive a well rested bonus. Before you sleep though, press select and wait until 1 am, then sleep. This gives you a well rested 10 percent skill bonus in addition to the stones 20 percent. Also it is nine in the morning. Go to Sigrid's house and sneak attack Hodvar untill level ten. Using a iron dagger makes this easier. Put all your points into health. Now it is time to assign some perks.
Allusion- novice and apprentice
Sneak- Sneak and muffled movement, light foot, and silent roll
For the rest of the points put them into enchanting, heavy armor, block

Now continue attacking Hodvar but do not level up. If you go into the level up screen you will be forced to take on all levels you've accumulated or reload. The reason you don't want to is because you'll start seeing frost trolls right outside the village and have a very hard time. In a while you'll take all your levels and even frost trolls won't be a problem, but for now they will smash you so hold off. Level sneak up to 50 on Hodvar. More is fine but unnecessary.

Buy or smith a full suit of heavy armor of any type. Speak to the trader in town to get his quest leave through the bridge. Now, at the first wolf you can grind some more though it's not necessary. Sit there and let him hit you to level up heavy armor. Use heal every so often. Alternatively, you can strap down the block button and the wolf will do so little damage that you'll regen faster than he can kill you. You really only need block at 50 for now. Just make sure to back up against something so he doesn't push you around. If you smithed all your armor as steel and improved it, and have a perk in heavy armor, then the wolf might not attack you at all because it wouldn't do any damage. Change your gear if this is happening. Getting heavy armor to 70 is an important break point as it will allow sneaking while wearing it. Very tedious grinding to get to that, however, and not that important yet.

Now do the trader's quest. Do it however you like, just don't level up. Get the dragon word of power and also the dragon plate. Next we head towards Whiterun. Speak to the Jarl and complete the first dragon killing quest. Now head north to Winterhold and the College. Enter the college and start it's quest line. Almost immediately you will be given some crappy mage gear. Equip it and cast some illusion spells on random enemies if you didn't choose High elf for your race. Speak to Drarvis Neloren and buy the apprentice illusion robes and hood as well as a muffle tome. This will cost 2500 to 3500 gold. You might need to go back to Whiterun and quest a little to get the money. Stick Muffle on one hand and continuously cast it as you quest around and do whatever you like as long as you don't go to the level up screen.

An important early quest is Azura's Star quest at the shrine south of Winterhold. Make sure to get the the black star by speaking to the elf at the inn upon completion. This is important for enchanting.

Joining the Companions to get Skyforge steel equipment, especially daggers, at least two, is a very nice early task.

Another early thing to accomplish is finding a soul trap weapon of any kind and disenchanting it. You need 1500 hundred gold. Go to a weapon vendor and spam waiting for 48 hours to refresh his inventory until they have one for sale. Then enchant one of your best daggers with soul trap.

Once you have illusion to 75 by casting Muffle all the time, it's time to let loose the floodgates on your levels. Spend perks as follows:
Illusion-adept illusion, silent casting, nothing else.
Sneak, max out, though only put one point in it's first perk. Don't put any more in that first one.
One Handed-invest in the first perk 5 points, and two into Dual flurry. NO other points yet. Can put more once optimized.
heavy armor- Conditioning if level 70
Block-elemental blocking. No power bash. Invest more points into the first perk as you like.
Enchanting-all you can
Smithing- all you can

Spend your stat points mostly on health. Give several to magicka though, especially if you didn't choose High Elf.

Depending on how much you've ground skills so far, you might not have all the perk points necessary to get all of these. If so, they are listed in priority order. Adept illusion and assassin's blade are the most important.

Now there's two large tasks left to do to finish up optimization. As preparation, aquire wealth via pickpocket or questing. Buy Naloren's Invisibilty tome and the best Illusion robes you can afford. Go to any vendor-mage and buy all his empty crappy soul gems and grand soul gems. Spam 48 hour wait if necessary. There are a lot of crap soul gems to steal around the college too. Grands are expensive, though,so if you have ground levels a lot you can spend some extra perks on the speech tree. It really does make things go faster.

Now, Go to Riften and complete the Dark Brotherhood Quests and equip the bracers that boost your damage ridiculously. It's an extensive quest line.

If you intend to use any magic besides invisibility, Complete the Mage College questline to get the archmage robes and daedric mask. They are enough to allow ample invisibility casting and allow the flexibility to use other magic trees without equipment exchange, provided you're wearing some decent enchanted jewelry.

There, you're done. Along the way you'll be using that soul trap skyforge steel dagger, filling up soul gems so use them to enchant things (use crappy gems for leveling the skill, and grands for enchants you want to keep like pickpocket, lockpick, and magic tree mana reduction sets) and buy new empty ones often.

Once you have Enchanting at level 100, you can dual enchant magic tree mana reduction mods on four different pieces of equipment, wear them all at the same time, and have infinite mana for that specific tree. Restoration, Destruction, and alteration then become incredibly easy to level to 100 without perk investment. Pickpocket and lockpick also become very easy to augment with enchanting even at low levels.

Level Pickpocket in Riften because you can pay off the guards so easily.
For Alteration, use Detect life in Riften while holding a random potion with Telekinesis to level it very quickly.
For Restoration, spend a few perks and get a decent tome and let something hit you while you wear heavy armor to get both to 100 while strapping down a button.
Level Smithing by buying/hunting leather and hides and make leather bracers ad nauseam.
For Destruction, cast flames on Shardowmare, obtained from the Dark Brotherhood questline

Full perks in Restoration with magic-friendly dual-enchanted heavy dragon-armor? yes please. Not that you need it really. In fact you won't need it at all. But we're going for God-like power level here, and the more unnecessary the better. This is just something to do at level 55-ish. Some of the harder dragons will actually make good use of this sort of thing.

Lastly, a note on how Invisibility Sneak Killing works. Keep invisibility up at all times. Stay crouched when approaching an enemy and hit them with a good dagger. the Assassin's blade perk grants a 15X multiplier to damage, which is very overpowered. The Dark Brotherhood Bracers and one-handed perk bonuses further improve this. As if that weren't enough, you can easily keep a second dagger on the switch for bosses to easily one shot them even without a power strike. Normally Sneak dagger attacks are difficult to consistently pull off even with full sneak perks because multiple enemies will turn it into a tediously long game of hide and seek. However, recasting Invisibility when discovered by enemies throws you right back to hidden status nearly every time. You'll sneak attack critical enemies constantly even if they just found you. You don't need to hide and wait for them to forget about you, you can just keep whacking away like a spastic Tonberry.

Now please, enjoy, and thanks for reading.
