To be installed on the server. Installation on clients not necessary unless they are hosting their own LAN servers.
This mod limits you to a set number of lives per world. By default, when you die, you will lose a ratio of your permanent health, leaving you less and less hearts/HP after every respawn.
When you finally run out of lives, depending on the config, you will be forced into Spectator mode (not available for MC 1.7.10) or banned from the server for a set amount of time.
!limitedlives in chat to find out how many lives you have left or how long you have left to respawn.
