create a minecraft item that has the following description: Create a Minecraft mod that adds a new item called “Amulet of the Depths”. The item should be obtainable in a simple recipe or creative mode. When the player is holding this amulet in either their main hand or off-hand, the game should treat the player exactly as if they were underwater. This means: the player receives full underwater breathing mechanics (including air bubbles on screen), their environment and physics should behave as if they were submerged in water, and any checks that determine whether the player is “in water” should return true while the amulet is held. When the player stops holding the amulet, all these effects stop instantly and the player returns to normal behavior.
Edit v2: Add the following mechanic to the amulet: when the player wears it, they become irreversibly pulled toward the ground. Their weight increases significantly, preventing them from jumping higher than one block. Any attempt to jump higher should automatically fail, and the effect must be clearly noticeable both visually and in gameplay
