Nether Wart is a key ingredient in potion brewing, found exclusively in the Nether. It grows naturally in Nether Fortresses, typically in soul sand patches near staircases or chests. Nether Wart is essential for crafting Awkward Potions, the base for most beneficial potions in Minecraft. It can be planted on Soul Sand and cultivated in the Overworld or Nether, making it a renewable resource for potion brewing. Due to its importance in brewing, gathering and farming Nether Wart is a priority for players exploring the Nether.
