Just Another Lifesteal is a hardcore lifesteal server built around a simple idea: players decide who lives, who dies, and who gets stronger. Kill someone and their head drops, eat it to gain soul power, and once you build up enough you earn an extra heart. Soul power is tied to your playtime and achievements too, so the more you play, the more dangerous you can become.
The economy is fully player-driven, so there is no buying or selling straight to the server. You earn money by completing achievements, plus small amounts while you are online or even when you have been away. That money is then used for trading with other players and for reviving friends, including through a Herobrine shrine, some cash, and a head to bring the fallen back.
It is semi-anarchy, so you are free to do what you want in the world, as long as you are not cheating or hacking. If you like lifesteal with a harsh survival edge, player-made politics, and a world where fights actually matter, this is the kind of server for you.
