This modpack was built with hardcore in mind, while adding more to the vanilla experience. This pack is meant to be played without natural health regen. I did my best to help performance, so this modpack should run on lower end systems.
Some key things to mention: Campfires give the regen effect, Hitting mobs a little after being hurt allows you to heal back some of the damage, other players can pick you up for a configurable amount of time if you get downed, dying destroys your inventory and you will resurrect after a certain amount of time. You can change any of this in the configs.
