1. The point of this plugin is to reliable simulate the avatar world, yes? Then why wouldn't there be spirit water?
2. Yeah, because the equivalent of magic water with properties to heal you wouldn't be magic water with properties to heal you. Not everything in the plugin is the exact same as it is in the show, that is because this is a plugin, not a mod, and you wouldn't be able to easily add spirits or spirit water.
3. The Main point of this thread, is to, believe it or not, improve healingwaters, which seems to be quite different in the plugin then it is in the show, and can be easily changed to look a lot better.
