Fishing rod function, levitation potion and a new profession for a villager

Adding the ability for players to catch items from mobs with a fishing rod without killing them is a good addition to the fishing rod; most pros don’t even use the fishing rod for its intended purpose, well, except for most beginners, and this is generally a minor addition that may have some significance at the beginning of survival. Adding a Potion of Levitation I understand that most players will use the Potion of Levitation for fun, but it can make some things easier, such as completing the "impossible is possible" achievement. The method for obtaining a levitation potion will be similar to the Dragon's Breath potion, the potion can be obtained by pressing an empty bottle on a magic projectile (thus allegedly collecting a magic projectile inside the bottle) and then in the potion maker you can make it explosive and throw it at other mobs so that they can also apply this effect .New profession for the villager: geologist, essentially geologists in reality study the properties and structure of various types of rocks and mark mineral deposits. I would like the villager geologist at the initial levels to sell not the most valuable minerals in the game such as copper or coal , and at the maximum level he sold a “special compass” that would indicate deposits of all types of fossil ores, from coal to diamonds, and the workplace for it would be, for example, a car assembler, which they seem to be planning to add in 1.21. However, you can change it and make it more balanced, thanks
