★ Personal Healer is a Skript I've created with some help to make it into a great donor perk. When you give the permission to one of your players it will spawn a priest villager on that player for and if he has the correct permission than he can right click the villager to heal him for 5 hearts. This is a lightweight plugin that doesn't take up much space since we use Skript to run it.
