Mob Lifesteal

In this mod, mobs don't just hurt you, they remove a heart from your maximum permanent HP and take it themselves! Essentially, every hit you take makes you weaker while making your enemies stronger.

Your only hope? Every mob you kill regains you one heart.

And no, you can't go above 10 hearts sorry ;)
