Mine we're:
*When I was making a mod which I have now abandoned without even posting it, I added in an item, which was a 1/30000 drop from digging stone and I got the item in the first 10 stone nodes I dug.
*Once, I had very low HP left and I fell down from a great height several times in a row, but 3d_armor "heal" saved me during all of those falls.
What about you?
