A quick word about intelligence and wisdom. The higher your intelligence is, the faster you will raise your skill. I've heard it recommended that you shouldn't try to train in a skill without a minimum of 100 Int. For us Shamen, that's not always easy to acquire. So, an investment in int raising items will pay off in the long run.
Wisdom controls the success in making an item.
When you are trying to make potions to sell and you want the most bang for your plat, get your wisdom as high as possible first. That way, hopefully, you will fail less. Int for skill raising, Wisdom for success. Most of the lower level potions aren't worth much and you will end up either wasting them or selling them to a vendor at a fraction of what it cost you to make. So, int can't be stressed enough at the lower levels.
