Minecraft too easy for you? After playing the game for years, I can't help but feel it is. Or perhaps it's too hard with all the crazy mods you've added? Scaling Health aims to balance out modpacks, by allowing players, mobs, or both to gain extra health! Or players can start with less health, if that's what you want. The mod is highly configurable.
This mod started as an unofficial port of Difficult Life, a mod I personally loved playing with. Eventually, I decided to rebuild the mod from the ground up, fixing bugs, adding more config options and widening the scope of the mod to include players who need an easier experience, not just a harder one. The difficulty system is very server-friendly, unlike the system used in Difficult Life.
