The Elder Scrolls III: Morrowind; Buckmoth Legion Fort near the beginning has a person in the basement that sells a spell damaging a skill. Buying it and going to a spellmaker, you can craft a spell to drain a skill for 1 second on self 100 to 100. You can make one for every skill and use that spell to reduce your skill to 0 for 1 second. Cast it in front of a trainer, and it will only cost you 1 gold to train and raise your skill level. Then, the spell will wear off restoring previous skill points, so you've raised your skill for one gold. You can raise every skill to 100 pretty easily, and it even works on Xbox so that you can be OP without the use of the command console.
