Pretty lightweight pack that makes Minecraft Harder (while trying to keep it fair).

You only have 3 lives, you can gain more by completing some Advancements, like entering the Nether or playing baseball with a Ghast.

You can still play in Hardcore with 1 life only, good luck.

Mobs chase you from farther away and have a few more tricks up their sleeve, like Creepers breaching or Zombies mining below sea level.

Vanilla tools and armor are disabled, you must use Tinkers ones.

To start check advancements that will help you get ... started.
