Pointed Dripstone

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

Obtaining
Pointed dripstone can be found in dripstone caves, which can generate using only the buffet or custom world type.

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.

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.

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

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.

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 dripstone at the tip of a stalactite does not produce drip particles or fill a cauldron. 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.

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 gamerule  is set to.
