Been said before, but... luck vs misfortune

[Zurai]

If I ever got any gems from the witch events, it was a very small amount of either Nature or Air gems which Avalon gave me a supply of anyway (which would make it hard to track). I'm 100% certain that I didn't get any other types of gems from the witch, and I'm fairly sure that I didn't get more than 3-4 Air or Nature gems either.

Still, you're right that if you do get gems, that would force it to be classified as a neutral event, which would bring the split of good/bad to 15:13 or 53%:47%. It also further dilutes the ratio of "major" bad events to "minor" bad events, from 9:4 to 9:2.
