A brown mold, F, is a type of monster that appears in NetHack. The brown mold is a type of mold that has an affinity to cold, and like all molds it is sessile and lacks limbs, eyes or a head.
A brown mold has a passive attack that can trigger when it is attacked in melee, dealing cold damage against attackers without cold resistance dependent on their level while increasing the mold's HP by half the damage inflicted[1][2][3][4] - if enough HP is gained from this, the mold will undergo division, halving its HP (rounded up) and creating a second mold with almost the same amount of HP.[5][6][7] Brown molds possess poison resistance and cold resistance.
Eating a brown mold corpse or tin has a 3% chance each of granting poison resistance or cold resistance.
Generation
Randomly generated brown molds are always created hostile.
Strategy
Brown molds are not threatening to a hero that has cold resistance, and even heroes without the property can avoid YASD against one by remaining attentive. Any form of ranged attack can dispose of a brown mold easily; while pets are also capable of handling them, some early pets may have trouble dealing enough damage to outpace the mold's HP gain and passive damage.
Brown molds can provide an early source of cold resistance and poison resistance for a hero, in spite of the low odds.
History
The brown mold first appears in NetHack 3.0.0.
Encyclopedia entry
Mold, multicellular organism of the division Fungi, typified
by plant bodies composed of a network of cottony filaments.
The colors of molds are due to spores borne on the filaments.
Most molds are saprophytes. Some species (e.g., penicillium)
are used in making cheese and antibiotics.
