A Nether Fortress is a naturally-generated structure found in The Nether. Nether fortresses were first introduced in the 1.9 Pre-Release and 0.12.0 for the Pocket Edition. They include bridge structures constructed of Nether Brick, Nether Brick Fences, and Nether Brick Stairs. They are the only place that Nether Wart can be naturally found. They also often contain many Blaze Spawners.

A furuncle, also known as a boil, is a painful infection that forms around a hair follicle and contains pus. A carbuncle is collection of boils that develop under the skin. When bacteria infect hair follicles, the follicles can swell and turn into boils and carbuncles. A furuncle starts as a red lump. It may be tender. The lump rapidly fills with pus, and as it grows it may burst. Furuncles, boils, and carbuncles typically affect the thighs, armpits, buttocks, face, and neck. Individuals with weakened immune systems, adolescents, and young adults are more susceptible to furuncles than younger children or older adults.
