Liquids are minecrafts "liquid blocks" which are being used to supply farm plots with water, create mob farms and mob traps, travel over by boat and can even be used to hide your secret base. But not all of minecraft liquids are like that, as lava will burn you quite fast and cannot be travelled over by boat. The Soul Forest Mod adds 1 type of liquid, Soul Water.
Soul Water is the main water-source of the Soul Forest Dimension and will be seen quite a lot. It will not hurt the player, but when Soul Water and Water touch each other something will happen.
In order to pick up Soul Water you will need a Soul Bucket which you can craft the same as a normal bucket except you have to use Titanium Gems instead of Iron Ingots.
