The Bottled Wind item, when used, snaps on to the nearest structure within a cone of your view direction, indicating what type of structure it is and how far away it is.
You can then put an ender pearl in your off hand and use it to shatter the bottle, letting the winds carry you to the surface where the structure is. It may or may not be entirely accurate, but is always relatively close.
You can simply use it as a compass, letting it navigate you to nearby structures.
This mod features a sophisticated scanning algorithm that is very performant on servers, allowing many people to use the item simultaneously to scan for structures while running smoothly with no problem.
The item is consumed when teleporting, and loses durability while being used to navigate. It has 64 durability by default.
