What I want: A plugin that lets you breathe longer under water while wearing the Leather Cap and also configurable in seconds in the config.yml. One example would be if you put the Leather Cap on your head (not in inventory) it activates the Potion of Water Breathing effect for X seconds as soon as you go under water. Going back up to the surface removes the effect. If that is too advanced it could just activate the effect as soon as you put it on your head. I've searched and tried a few similar plugins but they're not updated since 2012 and you can't configure the time limit for the effect. Ideas for commands: /scubahelmet reload - reload the configuration file. Ideas for config.yml: duration: <number in seconds> - the duration in seconds in which the effect is active. Ideas for permissions: None. Should activate for any player who has a Leather Cap on their head while going under water. When I'd like it by: As soon as possible.
