Dripstone [[Minecraft:feature]]s can be found commonly in [[Minecraft:dripstone caves]] biomes. There are three types of dripstone feature: '''large dripstone''', '''dripstone cluster''' and '''pointed dripstone''' (also known as '''small dripstone''').

== Description ==
Dripstone features generate inside large hollows in the [[Minecraft:dripstone caves]] biome. They can generate in water.

There are three types of dripstone feature:

*The first type is the "large dripstone", which takes the form of either a separated stalagmite and stalactite, or a stalagnate, and is composed of [[Minecraft:dripstone block]]s. Stalagnates generate around two positions selected on the floor and ceiling of a cave, which may potentially be separated by several blocks horizontally. The maximum possible size of a large dripstone varies depending on the available space.

*The second type is the "dripstone cluster"{{until|JE 26.2}} ("speleothem cluster"{{upcoming|JE 26.2}}), a patch of dripstone blocks replacing a section of a cave’s walls, floor and ceiling. Some [[Minecraft:pointed dripstone]] blocks will generate hanging from the ceiling and growing on the floor in these patches, attached to the dripstone blocks, forming detailed speleothem growths. [[Minecraft:Water]] puddles can also occasionally be found on the floor patches.

*The third type is the "pointed dripstone"{{until|JE 26.2}} ("speleothem"{{upcoming|JE 26.2}}), which is similar to the dripstone cluster, but only has a single stalagmite or stalactite.

When these types overlap, it results in pointed dripstone generating on the large columns of dripstone blocks.

== Trivia ==
*For a brief time in snapshot [[Minecraft:21w06a]], dripstone clusters were one of the only underground structures that did not generate correctly in negative y levels. This was because the developers initially hardcoded the minimum y level to be 0, intending to change it when changing the world height, then forgot to.<ref>{{tweet|henrikkniberg|1360164611622924288|(paus for meetings... back again, poking around in the code). Hmmm. Wait. What? Oh LOL! Yeah you'd be surprised how many bugs are caused by dumb things like this :)|February 12, 2021|archive=no|archiveid=20210212095140}}</ref>
