Be The Hero is a health donation system which allows players to donate their health to others in times of need!
For example: You and a friend are mining and your friend has found diamonds, on the way back put of the mine you get attacked by a creeper leaving your friend with only 1 heart of health and you with 7. You could then donate some of your health to ensure your friend who is carrying precious valuables doesn't die.
Simply place the BTH.jar file in your plugins folder before starting the server, once everything has started up use the "/bth" command in game followed by a target player.
If the target player has 8 or less hearts of health, one of your hearts will be given to him/her.
