Pointed Dripstone

Pointed dripstone is a block that makes up stalactites and stalagmites.

Natural generation
Pointed dripstone can be found in dripstone caves. They are also found in small groups inside ordinary caves.

Trading
Wandering traders may offer two pointed dripstone for one emerald.

Breaking
Pointed dripstone can be mined with any tool, but pickaxes are the quickest. Pointed dripstone breaks instantly when a trident is thrown at it.

Trading
Wandering traders can sell 2 pointed dripstones for 1 emerald.

Usage
Pointed dripstone comes in two different forms, stalactites and stalagmites. Placing a pointed dripstone between a stalagmite and stalactite without sneaking connects them. It can be waterlogged. Dripstone may be used for mob farms due to the fact that they deal damage but do not destroy items

Stalactites
Stalactites are created when pointed dripstone is placed on the bottom of a block.

Stalactites less than 11 blocks tall passively drip water particles (or lava particles in the Nether) in the absence of a liquid source, but these particles do not fill cauldrons. A waterlogged pointed dripstone at the tip of a stalactite does not produce drip particles. Waterlogging other parts of the stalactite doesn't affect the dripping.

If the block supporting a stalactite or any block of the stalactite is broken, all of the unsupported pointed dripstone below the broken block drops, causing damage to any player and mobs standing beneath it, similar to a falling anvil. The amount of damage is for each block of  falling distance after 2 blocks. Stalactites with multiple pointed dripstone cause multiple damage, however, damage immunity prevents most of the additional blocks to cause damage.

Cauldrons
When the uppermost block of a stalactite less than 11 blocks tall gets randomly ticked, it checks for a water source or waterlogged block two blocks above it and a cauldron within 10 blocks under the tip with no non-air blocks in between. If both conditions are satisfied, there is a $45/256$ (~17.6%) chance for it to drip water and fill the cauldron by one level. If there is a lava source above the stalactite, there is a $15/256$ (~5.9%) chance for it to completely fill an empty cauldron with lava instead, making lava a renewable resource.

Stalagmites
Stalagmites are created when pointed dripstone is placed on the ground.

Falling onto stalagmites multiplies the fall distance by four to calculate the total amount of fall damage, using the formula. Note that the distance travelled during last game tick of falling time is not included in this calculation, making it slightly off at higher distances; see for more information.

All mobs that are immune to fall damage do not take damage from falling into stalagmites, the same applies to the player if the game rule  is set to.
