Monster Monday: Arachnocalliope - Musical Doom Construct

Today's Monster Monday is the arachnocalliope, a mad construct that is like a magical cross between a spider and a pipe organ. Piping atonal, demoralizing notes with every movement of its many brass legs and every contraction of its armored bellows-abdomen, the arachnocalliope is a true visual and aural horror.

This eccentric contraption functions as a sort of anti-bard in combat, laying down de-buffs on its enemies with sonic effects. Not that it is helpless on its own, with two sword-like forelegs and a sonic breath weapon (no one is resistant to sonic damage!).

The genesis of this creature lies in my Graverobbers campaign (which I have not posted an update on in about 3 years, but it's still going). In one session, the players were fighting some constructs made by a creative witch whose chosen artistic medium was bone sculpture. Among the odd bone creations they fought was this arachnocalliope. I decided it worked pretty well as its own stand-alone monster, so I re-worked it a bit to be made out of normal materials and here we are. Some of those other bone creations, like the ballistocentaur and the triskeliettin may make an appearance here in the future, but for now you'll just have to use your imagination to wonder what those polysyllabic monstrosities might be.

This construct looks like a cross between a spider and an organ. Dozens of pipes protrude upward from its thorax, unleashing a barrage of eerie music with every movement of its legs.

Taking the form of a giant spider made of wood, steel, and brass, this unusual pipe-organ is powered by the mechanical action of the spider’s eight legs and a throbbing billows-sac contained within the abdomen. The eerie, atonal piping that they produce throws the minds of those who hear it into a disrupted state. Lore-keepers trace the history of this musical construct back to an eccentric travelling circus. When the arachnocalliope made its debut, its disturbing music caused a series of deadly accidents and audience riots. While its appeal as a musical attraction was short-lived, its potential as a weapon was realized by more sinister minds.

Construction
An arachnocalliope is made with 500 pounds of wood and brass, including dozens of meticulously tuned and magically treated pipes.

Plot Hooks and Encounter Ideas

  • The adventurers brought a mysterious cursed stone to the temple to have it studied by the priests there, but overnight it worked its corruptive magic. Now the cathedral is a twisted terror full of living gargoyles, demonic priests, and even a pipe organ with a mind of its own. Can the adventurers quell the evil, destroy the stone, and return the temple to normal before something even worse is summoned into this world?
  • The lair of the evil bard is guarded by his musical minions, accompanied by a wicked arachnocalliope.
  • All an eccentric noblewoman needs to complete her collection of rare musical instruments is a working arachnocalliope. She is willing to pay a grand sum of gold to any who can track down, secure, and return to her this rare and deadly musical 'instrument'.
