This modpack allows you to have 3-5 lives. You spawn in with 3, and if you lose all 3 you are set into spectator, similar to hardcore mode. There are more mobs, better biomes, the AI is improved; and more. Animations were changed to be better as well as the ability to throw items. That's just a sample of all that you can do.
