Nether Wart

Nether wart is a plant grown in the Nether.

Obtaining
Nether wart can be mined with or without any tool.

Natural generation
Nether wart sometimes generates naturally in nether fortresses as a plant, in patches near stairwells.

Farming
When planted on soul sand, nether wart grows through four stages, though the middle two stages have almost the same appearance (the difference is that the hitbox of stage 3 is one pixel taller). $$, the exact age can be seen using the debug screen, and the ages range from 0–3. Each random tick, nether wart have a 10% chance of growing one stage. At default random tick speed, each nether wart grows approximately every 13653 ticks on average. The growth rate is not affected by light or any other environmental factors. Bone meal cannot be used on the nether wart.

Nether wart can be planted only on soul sand. It grows in any dimension.

Nether wart is ready to harvest when it reaches its fourth stage (age:3). Breaking a fully grown nether wart yields 2 to 4 nether wart, while an immature one yields only a single nether wart. Using a tool enchanted with fortune increases the maximum number of nether wart dropped by 1 per level.

Brewing ingredient
Nether wart’s primary purpose is to brew the awkward potion, the base for all potions, but optional for Weakness.

Trading
Master-level cleric villagers buy 22 nether wart for an emerald as part of their trades.
