Free Archery Skill
Visit Faendal at riverwood (he's a wood elf that usually stands by the mill) and ask him to follow you. Then ask him to train your archery. (Have some gold around at least to make your first purchase of training). Ask to borrow something and take his gold. It's not considered stealing. Repeat the last two procedures as many times as you like.
NOTE: You can only level archery 5 times per level, but you level up slightly every time your archery skill goes up. This will work with any trainer who can also be a follower.
Dragon Tomb Location
Use a shout in front of a guard (not a dangerous one). A courier will deliver a letter from a "friend", giving you the location of another dragon tomb.
Easy Armor, Spells, and General Leveling
Set the difficulty to "Novice" and have a weak one-handed attack enemy hit you while healing. This will level the armor you are wearing, restoration, also may level up illusion.
The Elder Scrolls 4: Oblivion Reference
Search inside the museum of Dawnstar to find a display case containing a yellowing piece of paper with the symbol for Oblivion. Pick the lock and use a spell for a few seconds on the paper to turn it into a bucket.
Glitch: Easy Experience
Go to the village named "Riverwood" and find a house called "Alvor & Sigrid's House". Inside is a man named Hadvar. Rest until it is after 8 a.m. so that Alvor leaves the house. Sigrid and the young girl should remain downstairs and Hadvar will be upstairs. If he is not, just wait and he will come upstairs. Save the game before the next part in case something goes wrong. Equip your strongest sword or weapon that you want improved skill for, and sneak behind him until he cannot see you. Do a heavy strike and he will stumble to the floor. When he gets up will have no knowledge that you hit him. He also never dies, so it can be done indefinitely. Repeat the process to level up as much as desired. This will also maximize your Sneak skill, and whatever weapon type you are using.
Become a Werewolf
Go to the city of Whiterun. Move through the town until you reach Dragonsreach, which is the castle. While standing on the steps looking at the doors to Dragonsreach, look to your right. There should be a building that resembles a ship's hull. This is where the Companions are located. Go and join them. After a few quests you are given the chance to become a werewolf. To use your new ability, go to "Magic", then "Powers", then "Beast Form". Beast Form can be used once a day. You will turn into a werewolf and friendly humans will attack you. You will have increased speed, health, damage, and stamina. You cannot pick up objects. If you kill a human you can "Feed" on the corpse to regain some health and extend the duration of Beast Form. This is also useful for traveling great distances on foot. When the werewolf sprints, it runs on all fours, and moves much faster than a horse. The werewolf's stamina also regenerates very quickly.
At the beginning of the game, when you reach to the first town of Riverwood start chopping wood and find the man named Hod. He usually stands at the top of the sawmill during the day. He will pay you for "all the wood you can carry" as he puts it. However, there is no limit to how much you can make buy chopping wood and selling it to him. He never runs out of gold like the merchants. Chop and sell wood to him until you have as much gold as desired.
Easy Conjuration Experience
To do this, it is best to have the Bound Sword spell, because you are able to conjure two of these at the same time to gain experience faster. This works best when there is an enemy that is trying to fight you, but you are at an area that they cannot reach you (for example, fighting a troll or bear while you are too high for them to actually hit you). Use the Bound Sword spell, put the sword(s) away, then repeat the process. Doing this will increase your conjuration levels very quickly.
This trick requires dragons roaming around and being far enough in the Dark Brotherhood to have Shadowmere. When you find where a dragon is located, Fast Travel there so Shadowmere can be with you. Start the battle with the dragon. Do not worry when the dragon goes after Shadowmere, as Shadowmere is invincible and will fight and eventually will kill the dragon for you. Use the Bound Swords spell as described above and it will have the same outcome.
Easy Restoration Experience
Go to High Hrothgar. Go out the door to the area where you are taught the Whirlwind Sprint. Once you get outside, go to the right. You will soon find a small staircase that goes up to show that looks like a blizzard of some kind. Go forward just enough to start getting hurt by it and begin using the Healing spell. Your health will go down slowly because you are using the healing spell, but you will also gain experience. This is better than fighting an enemy and leveling up your experience because you can control how much danger you are taking by simply walking backwards.
Easy Smithing Experience
This process will require a bit of coinage, and the more money you have the better. Once you have a vast fortune, go to every town and visit each blacksmith. Buy all their Iron Ignots and Leather. Once you visit the last blacksmith, turn your leather into Leather Strips and make Iron Daggers at the forge. Continuously make Iron Daggers and your Blacksmithing will eventually reach 100. You can also try the dagger process with steel, but iron is cheaper. If you do not want to waste more money on iron, just make Leather Bracers. It is a slower process, but is still effective.
With about 5,000 gold, start in Whiterun and buy all of the Leather Strips and Iron Ingots from both blacksmiths (the one at the entrance and one at Skyforge if joined the companions). Forge Iron Daggers until you run out of materials. Fast Travel to Solitude (or Carriage Ride if not discovered) and do the same thing there with the Solitude blacksmith. Fast Travel back to Whiterun and both blacksmiths will have replenished their supplies of Iron Ingots and Leather Strips. With about 5,000 gold and selling the daggers, you can upgrade Smithing from level 26 to level 100 in about one or two hours and have full dragon gear. You do not have to worry about not increasing your other stats, as you can just save perks and use them whenever.
Easy Sneak Experience
At the beginning in Helgen's Keep, you will encounter a sleeping bear. Your guide states that you can either sneak past it or kill it. Just off to the left of where your guide stops is a small rock pile. Go to the back side of it, and you can sneak in the crevice there and remain hidden from the bear. Keep sneaking at the rock and your skill will increase. You can do this for as desired, because the bear only moves if it detects you. To make sure you are in a good location, sneak for a short time, then check your Sneak skill to see if it is rising. If not, move slightly closer to the bear and keep trying.
Note: This trick will also help you gain weapon experience. While doing the Molag Bal quest, and after you save the priest, go to the shrine. When he gets trapped in the cage, crouch behind him and hit him with the weapon of your choice. Note: Spells may also work too. He will heal quite fast, and he is invincible until he submits and you are forced to kill him for the Daedric lord. Note: Using spells will turn it into a real fight and your follower may become aggressive. However, it can still raise your Destruction level.
Moving When Over Encumbered
If you are over encumbered and are far away from a city, the fastest way to move is through the Whirlwind Sprint Shout. It can be used continuously and will get you to the nearest city quickly so you can sell. This also works when exiting caves and dungeons.
Get the Elder Scroll, then go to Paarthurnax and use the "Throw Voice" shout at him. A new voice will shout insults such as "Hey, ugly!", "Hey, skeever butt!", "Hey, melon head!", "Hey, melon nose!", "Hey, troll bait!", "Hey, slug-breath!", and "Hey, cheese brain!"
King Arthur References
Between Sundered Towers and Blackwind Bluff, you will find a cave called "Rebels Cairn" Inside this cave you must put a magic sword in a stone to open a door outside the cave to the left. You will find another sword in a stone.
Find someone that is shooting at a target for practice. Stand near the target and collect all the arrows. This becomes very useful if you are an archer.
