Weeping Vines

Weeping vines are plant blocks found in the Nether in crimson forest.

Natural generation
Weeping vines generate naturally inside crevices within the ceilings, or on huge crimson fungi in the crimson forest biome.

Post-generation
A huge fungus grown by bone meal on a crimson fungus generates weeping vines growing on it.

Each random tick, weeping vines have a 10% chance of growing one block downward. At default random tick speed, each plant grows approximately every 13653 ticks. Weeping vines stop growing once they reach the ground or when the block reaches an block state of 25, whichever is first.

Breaking
Weeping vines are broken instantly using any tool. They have a 33% chance to drop a single weeping vine when broken, increased to 55% with Fortune I, 77% with Fortune II, and 100% with Fortune III. They always drop a single weeping vine when broken with shears or a tool enchanted with Silk Touch.

Usage
Weeping vines can be placed on, and grow from, the bottom of a block. The bottom-most vine block always has a starting age value of 0, which increments every time the block grows. If the bottom-most vine block has an age below 25, it continues to grow given that there is free space below the vine. When the vine does grow, a new vine block with an incremented age value is placed beneath it.

Climbing
Weeping vines can be climbed by standing in them and holding the key. If there is a solid block behind the weeping vines, the key can also be used.

Compost
Weeping vines can also be used on a composter, with a 50% chance to raise the compost level by 1.
