Support for the mod has been officially discontinued. Try Keepers of the Stones II.
Keepers of the Stones is a magic mod that will add magic stones to the game with which you can become a master of one of the elements.
How to use it?
In order to activate the stone, it is enough to right-click the stone through the air. To deactivate the stone, press the "U" key. You will not be able to activate the stone if you are wearing armor.
How can I get stones?
You can get magic stones in survival mode by turning on the game rule - "Giving out stones when entering the world". After switching to using the command re-enter the world. When the world loads and the window appears, select the element that you like) When playing on a server with a mod, each incoming player will have a choice of non-selected elements (you can only choose one!). However, if the permission to re-select a stone is enabled, you can change the stone to any of the free ones using the /pw command.
