The following video demonstrates this plugin, with dirt at 100% slipperyness, enderdragon damage turned awesome, and at the end we also turned stone to 100% slipperyness with less interesting results than dirt.
Anyway, for the members of Nova Mundi, I encourage you to get on over to the forum so you can vote on this plugin. So far the only people who have votes are the staff, and I may say I'm a bit dissappointed.
Because of this you can click here to see an ugly video about what to click on to vote. I hope I made it blatantly obvious.
