Day / Night Factor
Just like the series, waterbenders are stronger when the moon is out. In this case, every night. How much stronger can be changed in the config, default is 50% stronger. (1.5 Multiplier) If you wanted to make waterbenders stronger / weaker, you can tweak that number to your liking.
You can also choose whether or not the message shows with the following permission node (Shows to everyone by default)
If a waterbender holds in the sneak button (Default:Shift) if there is no ability using shift bound to the slot selected, he/ she will swim.
