Felt like armor just isn't doing the job for you? Tried disabling your health regen, but just found it too unforgiving? Well, Natural Absorption will solve your everyday needs and even do your laundry for you! (Warning: does not do your laundry.)
This small mod gives you permanent absorption health that regenerates over time. The shield is not a potion effect, and will therefore stack with the absorption potion effect! In addition, it adds a new enchantment you can get on your armor to increase your max absorption health! You even replace armor's reduction entirely with absorption (disabled by default).
There's a properties file that allows you to change just about everything relating to natural absorption, from how much you start with and the max you can earn to how quickly it regenerates and how much you lose on death! If you want to disable the enchantment or even restrict it to only the enchant, you have that option as well! The properties file is generated in the 'config' folder in your .minecraft directory.
