A lumpy reddish fungus covered in knobbly rhizome growths, growing well in the dank underground dungeon. When active it will occasionally produce giant spores, which in turn will give rise to more ballistomycetes.

Useful Info

A ballistomycete is a plant-type monster, capable of spawning ballistomycete spores for both reproductive and combat purposes.

While ballistomycetes no longer generate in the dungeon as of 0.17, they can still be found in sprint or spawned by worshipers of Fedhas Madash.

Ballistomycete Life Cycle

  • Ballistomycete spores will wander the dungeon, occasionally leaving grown ballistomycetes in its wake. After wandering for a while, crashing into a creature, or taking damage, a spore will explode, damaging and confusing creatures within 2 tiles. This may also create a random number of new inactive ballistomycetes in the blast radius (2~3 on average)
  • When this explosion occurs, a random ballistomycete on the level is activated. Roughly 500 turns later, it will create a new spore, continuing the cycle.
  • If an active ballistomycete is killed, a random number of other ballistomycetes will activate.
  • There can be up to 25 ballistomycetes on a floor at any given time. Any spore explosions beyond that will cause damage and confusion, but nothing else.
  • Killing the entire colony will remove all moldy floor tiles.

Tips & Tricks

  • Giant spores and spore explosions create mold on the floor. When a new ballistomycete is activated, this mold lights up in a trail leading to it, giving you an idea of where to go next.
  • Killing inactive ballistomycetes does not cause others to immediately become active. Because of this, it's possible to "prune" an out-of-control outbreak without dooming yourself.
  • Magic Dart can reliably one-shot spores. Basic throwing items like stones also work, though a character with no skill in Throwing may not be able to hit the spore before it goes off in their face.
  • If you've killed everything attached to a particular patch of mold and it doesn't disappear, there's probably another patch (or maybe just a single spore) lurking somewhere else on the floor.

Hyperactive Ballistomycete

This ballistomycete is in a state of all-out reproduction. It is constantly ravaged by explosions of spores, damaging everything around.

Hyperactive ballistomycete.png Followers of Fedhas Madash may use its Evolution ability to upgrade a ballistomycete to a hyperactive state. Hyperactive ballistomycetes will repeatedly cause explosions of spores similar to those of giant spores before eventually dying, leaving more ballistomycetes in their wake. They are somewhat more durable than normal ballistomycetes, but this is offset by the damage they constantly do to themselves.


  • Prior to version 0.17, ballistomycete colonies could spawn naturally instead of being exclusive to followers of Fedhas.
  • Prior to version 0.14, destroying a colony of ballistomycetes would give you about 500 experience.
