TownyWild is a plugin that depends on Towny and that allows you to easily set a specific protection time when players exit a town, it makes both the attacker and the victim unable to attack each other until the countdown is over. I made this plugin to avoid claim campers killing off players going outside of their towns for a small amount of time.
Updates are focused on the latest supported version (1.20.1). Spigot is supported but might not be in the future.
