the Jester
Legend
What's your source? Or did you come up with the probabilities yourself?
The latter. I typed the numbers out, then looked at the list and started by asking, "What are the most and least common weapons to be enchanted in my game?"
I did bear in mind the 1e random magic sword types a little bit, but only a little. In 1e, you were exceedingly unlikely to find a magical two-handed sword.
