Bell

Bells are transparent animated block entities that produce a bell sound when.

Obtaining
A bell does not have a crafting recipe and requires a pickaxe to be mined or will drop nothing.

Natural generation
Bells can generate naturally in all village variants, usually near the center of the village in the meeting point.

Trading
Apprentice-level Armorer villagers have $1/3$ chance to sell a bell for 36 emerald. Apprentice-level Toolsmith villagers sell a bell for 36 emerald. Journeyman-level Weaponsmith villagers sell a bell for 36 emerald.

Usage
When the side of a bell is, it will produce a sound as well as a "swaying" animation. Bells can be anchored to the side of blocks, ceilings, and floors.

When rung, villagers will run into their houses immediately as they do at sunset. Additionally, the bell will also apply the Glowing effect to any raid mobs within 32 blocks, and produce a resonating sound if any such mobs are within range.

Block entity
A bell has a block entity associated with it that holds additional data about the block.
