ELDER SCROLLS IV: OBLIVION TIPS & TRICKS
Easy Alchemy level
Steal a mortar and pestle. Steal a lot of food items and turn them into potions. It should not take too long before you reach the Master Of Alchemy level.
Jail Sneak increase
Whenever you get in jail, go into sneak mode. Move around for awhile and your Sneak level will rise.
Easy money
A quick way to make money without going to the trouble of stealing or fighting for it is to join a guild. When you join a guild you will have access to a number of guild halls all over Tamriel. It seems that the guild has no problem sharing their wealth.

Cure for vampiricy
This is why you need to be allowed in the University. Go in and talk to the mage. He will tell you to talk to a man in Skingrad. Do as he says and run errands for whoever you need to talk to. Eventually you will be allowed to get rid of your vampiricy.
Good armor
At the beginning of the game after the King's convoy is attacked, quickly take the dead guard's katana and armor. This will make slaughtering rats and defeating trolls a lot easier.
