Bell

"Ding dong, who's there? A RAID? GET INSIDE!!!"

- Adrian Östergård

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

Obtaining
A bell requires a pickaxe to be mined or it will drop nothing.

Bells cannot be crafted, only found or traded.

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 emeralds. Apprentice-level toolsmith villagers sell bells for 36 emeralds. Journeyman-level weaponsmith villagers sell bells for 36 emeralds.

$$, apprentice-level armorer villagers have a 50% chance to sell a bell for 36 emeralds. Apprentice-level toolsmith and weaponsmith villagers will always sell a bell for 36 emeralds.

Usage
When the side of a bell is, it will produce a sound as well as a "swaying" animation. $$, bells can also be rung by any damage-dealing projectile. $$, they can be rung using redstone or any projectile by right clicking. Bells can be anchored to the side of blocks, ceilings, and floors. Also, if the player the bell while villagers are sleeping, all of the villagers will wake up.

When rung, villagers will run into their houses immediately as they do at sunset. The bell's functional range for sending villagers to their home is 31x31 squared, with the bell counting as 1. This gives the bell an effective area of 961 blocks per plane and totals the bells effective area to 29792 blocks affected in the whole square.

Additionally $$, if a bell is rung and there is a raid mob within 32 blocks, the Glowing effect will be applied to all raid mobs within 48 blocks. It will produce a resonating sound once this process is complete.

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

Trivia

 * $$, bells used to have unused data values with only side texture without bell which cannot be rung.
 * $$, bells will deflect any projectile that does not disappear when hitting a surface (arrows or tridents).
 * Despite some villages generating with more than one bell, villagers only need one of them to meet and spawn iron golems.
