About this Mod

You just fell of a cliff and lost 6 hearts, but what happened to your legs? Don't you feel a little nauseous from the fall?

Realistic Health adds new mechanics to Minecraft that relate to the health system, such as negative effects from fall damage, regenerative sleep, and more.

It's current features include:

  • All entities taking damage from blocks such as Stonecutters, Amethyst, Coral, and Rose Bushes. (Along with custom death messages for each if you use the ResourcePack)
  • Gaining Regeneration while you sleep.
  • Different negative effects for falling from different heights. (Nausea, Slowness, Blindness, etc.)
  • Heartbeat sound and negative effects while on low health. (Slowness, Nausea, Darkness)

Negative fall damage effects can be reduced or negated based on the level of Feather Falling that your boots have. Feather Falling I reduces effect duration by 1 second, II by two seconds, and III by 3 seconds. Feather Falling IV negates the effects completely!
