This would be a skill tree system that uses the points value that you see when you die. When you die any skills you buy will stay but you will lose all the points you saved up, but you can refund any skill to get some points back if you changed your mind on what skill you want, or you can just save up your points and get all of them. The skills wouldn’t be anything that actually makes your character stronger it would be for things you would find in the f3 screen on Java. Things like biomes, cords, and chunk info for finding slime chunks or other info. There can be a book in your inventory next to the crafting recipe book that you click to see the skill tree and your point value each skill can cost 100 points or so and some skills can be biome recognition making it so that when you go into a new biome it will show up on the top left or right of the screen what biome you are in then it will fade away until you go to a new biome another can be the coordinates so that they can be earned instead of turned on. The point of a system like this is so that people who are new to minecraft or don’t have access to the f3 screen or who want to stay immersed into the game without using f3 can use the skill tree to know how to find new biomes and information about there world.
