I think we also need to look at the difficulty for adding the 2nd, 3rd, 4th and 5th materia.

What do you guys think would be fair?

- 1st is 100% success, we know this
- 2nd, 80% success?
- 3rd, 60% success?
- 4th, 40% success?
- 5th, 20% success?

Does this sound reasonable? With these odds you have something like a... 4% chance of getting an item from basic to fully decked out, without it breaking.
