Buy or steal a horse. You can get one in Whiterun. Learn the Soul Trap spell. Then,
use the Soul Trap spell on your horse. It will not harm your horse, but it will keep
leveling up the Conjuration skill. Repeat this as much as desired.
This trick works best with the Bound Sword spell, as 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
to level up your Conjuration skill 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, but do not
worry when the dragon goes after Shadowmere, as Shadowmere is invincible and will
fight and eventually kill the dragon for you. While he is fighting the dragon, use
the Bound Sword spell, put the sword(s) away, then repeat the process to level up
your Conjuration skill quickly.
Easy Destruction skill
When you join the Fighter’s Guild, you will be prompted to go outside and duel with
one of the members. When you are outside, switch to destruction magic, and use it
against the opponent repeatedly. He will keep telling you to use a sword, but you
will gain experience, and he will not die. Repeat this as much as desired to get easy
XP for magic.
Easy Pickpocket skill
Go to jail in Riften, then unlock your cell door. Directly across from your cell is a
guy named Black-Briar. You can pickpocket him even after he catches you. Pickpocket
all of his stuff, then place it back into his inventory. Repeat this as many times as
desired to easily increase your Pickpocket skill level.
Easy Restoration skill
Go to High Hrothgar. Go out the door to the area where you are taught the Whirlwind
Sprint, then go to the right. Look for a small staircase that goes up to a blizzard
of some kind. Go forward just enough to start getting hurt by it, then start using
the Healing spell. Your health will go down slowly because you are using the healing
spell, but you will also gain experience. This method is better than fighting an
enemy and leveling up your experience since you can control how much damage you are
taking by simply walking backwards.
Easy Smithing and Speech skill
Every time you go to a forge, make sure to talk to the person in charge of it, and
buy all the iron ingot and leather or leather strips they are selling. Then, make as
many leather strips as it takes for each iron ingot. Take it to the forge, and make
an iron dagger that only takes one of each ingredient to create. If you sell it back
to the merchant, sell it one at a time so you create more transactions to level up
the Speech skill.
