The Life-cycle of the Gelatinous Cube... Part 4

I've previously described the way in which Gelatinous Cubes are created, but that details the manner in which they reproduce whilst wandering dungeons and other underground places. What follows is a description of the creature from which these cubic seeds are originally sown.

 

MOTHER OF ALL CUBES

FREQUENCY: Very Rare
NO. APPEARING: 1
ARMOR CLASS: 2
MOVE: none
HIT DICE: 450 hit points
% IN LAIR: 100%
TREASURE TYPE:  See below
NO. OF ATTACKS: 1
DAMAGE/ATTACK: 4-40
SPECIAL ATTACKS: Paralyzation
SPECIAL DEFENSES: See below
MAGIC RESISTANCE: See below
INTELLIGENCE: Semi-
ALIGNMENT: Neutral
SIZE: L (120' tall)
PSIONIC ABILITY: Nil
       Attack/Defense Modes: Nil

Somewhere deep in the earth and at the middle of a vast cavern lies an ancient creature known as the Mother Of All Cubes. Although only one such monster is thought to exist, dwarf and gnomish folklore hints at there being more. It is rumoured that Cubes and other gelatinous forms occasionally return to the Mother in order to have their treasure absorbed by it, creating a vast horde at its centre.

The Mother will always be surrounded by at least 100 Cubes, which will protect it from any attacks, and it can also calve 4-40 new Cubes per melee round should the need arise. The creature can be hit by all forms of weapons, and attacks by fire have normal effects. It is unaffected by cold unless it fails its saving throw. Electricity, fear, holds, paralyzation, polymorph and sleep-based attacks have no effect upon it. Any creatures that can get close enough to come into contact with the Mother will receive 4-40 points of damage and require a saving throw versus paralyzation, or will be anaethetized for 1-10 months (during which time they will be at the mercy of its cubic offspring).

Description: this creature resembles a huge, polychromic gelatinous sphere that radiates a slight greenish glow. Although semi-transparent, there is a dark mass at its centre, and light is reflected and refracted though the creature in a very odd manner. Outwardly spherical in shape, it's surface is made up of a multitude of facets.The main part of its body rests on an amorphous mass from which Cubes sprout or are absorbed.

The Life-cycle of the Gelatinous Cube... Part 3

So, after some time away from my blog, here's another gelatinous monster. This one is somewhat odd, insomuch that it has power over the Gelatinous Cube and the various other types I've described previously. It's also accompanied by a somewhat scrappy colour scribble, which will hopefully give some idea of its appearance.

ORANGE OCTAHEDRON

FREQUENCY: Very Rare
NO. APPEARING: 1
ARMOR CLASS: 2
MOVE: 16"
HIT DICE: 12
% IN LAIR: Nil
TREASURE TYPE:  T (75%), Z (75%)
NO. OF ATTACKS: 4
DAMAGE/ATTACK: 3-18
SPECIAL ATTACKS: Paralysation
SPECIAL DEFENSES: See below
MAGIC RESISTANCE: See below
INTELLIGENCE: Exceptional
ALIGNMENT: Lawful Evil
SIZE: L (10' octahedron)
PSIONIC ABILITY: Nil
          Attack/Defense Modes: Nil

The Orange Octahedron is the stuff of legend. It is not known whether there is more than one of these dreadful creatures and it may be some unknown form of demon or the result of some dark, ancient magic. In the folklore of gnomes and dwarves, the Octahedron is the evil sibling of the fabled 'Mother of All Cubes'. It travels throughout the various Material planes, searching for its preferred treasure.

It has power over cubes and their other gelatinous incarnations, and can summon 1-6 (of any form) at will. It exudes Fear in a 5" radius (saving throw vs. wand applies) and can strike out with up to four 20-foot long pseudopods, each causing 3-18 points of damage. Any creatures touched by these requires a saving throw versus paralyzation or will be anaethetized for 5-50 melee rounds.

It usually floats several feet above any surface, although is capable of flying at greater heights. The Octahedron can be hit by all forms of weapons, and attacks by fire have normal effects. It is unaffected by cold unless it fails its saving throw, in which case their movement rate is halved. Electricity, fear, holds, paralyzation, polymorph and sleep-based attacks have no effect upon it.

Description: this creature resembles a large floating octahedron that radiates a slight orange glow. It is gelatinous, semi-transparent and covered by numerous scratches, gouges and pock marks. There is a dark mass at its centre which is made up of the magical books and scrolls it has collected over many years. It can speak the language of any intelligent creatures and will use trickery if it thinks that it may be able to add more treasure to its collection - although it is also very willing to take such items by force.

The Life-cycle of the Gelatinous Cube... Part 2

Carrying on from my initial post about the cube, here are a few later stages in its life-cycle: the gelatinous dodecahedron and icosahedron...

GELATINOUS DODECAHEDRON

FREQUENCY: Rare
NO. APPEARING: 1
ARMOR CLASS: 6
MOVE: 6" (9" if rolling)
HIT DICE: 5
% IN LAIR: Nil
TREASURE TYPE:  See below
NO. OF ATTACKS: 2
DAMAGE/ATTACK: 1-10, 1-3 (see below)
SPECIAL ATTACKS: Paralysation, crushing, surprise on 1-3
SPECIAL DEFENSES: See below
MAGIC RESISTANCE: See below
INTELLIGENCE: Semi-
ALIGNMENT: Neutral
SIZE: L (10' dodecahedron)
PSIONIC ABILITY: Nil
     Attack/Defense Modes: Nil

Should a gelatinous cube survive into its thirtieth year, it will seek some dark and remote place in order to tranform into a 12-sided dodecahedron. As part of this transformation it will gain some form of very basic sentience, which in turn will make it into a somewhat active hunter. Although it usually moves from place to place on one of it's twelve flat faces, if the circumstances allow (i.e. if it is at the top of a slope or flight of stairs) it can roll and gain some speed when making an attack. The dodecahedron can inflict 1-3 points of crushing damage for every 5 hit points it possesses when attacking in this way. Normal or rolling attacks will also require a saving throw versus paralyzation or the creature touched is anaethetized for 3-30 melee rounds. It will also inflict 1-10 points of damage per melee round when surrounding and digesting its victim.

As is the case with their cubic incarnation, dodecahdrons sweep up metallic and other items as they move around and so can contain treasure types J, K, L, M, Q, as well as potions, daggers and similar items.

Dodecahedrons can be hit by all forms of weapons, and attacks by fire have normal effects. They are unaffected by cold unless they fail their saving throw, in which case their movement rate is halved. Electricity, fear, holds, paralyzation, polymorph and sleep-based attacks have no effect upon them.

Description: these creatures are large 12-sided masses with somewhat rounded edges. Although usually hard to see, their movement may be discerned when the creature is rolling as light is reflected by one or more faces.

GELATINOUS ICOSAHEDRON

FREQUENCY: Very Rare
NO. APPEARING: 1
ARMOR CLASS: 4
MOVE: 8" (12" if rolling)
HIT DICE: 7
% IN LAIR: Nil
TREASURE TYPE:  See below
NO. OF ATTACKS: 2
DAMAGE/ATTACK: 2-12, 1-6 (see below)
SPECIAL ATTACKS: Paralysation, crushing, surprise on 1-2
SPECIAL DEFENSES: See below
MAGIC RESISTANCE: See below
INTELLIGENCE: Low
ALIGNMENT: Neutral
SIZE: L (12' icosahedron)
PSIONIC ABILITY: Nil
Attack/Defense Modes: Nil
 

Once the gelatinous dodecahedron survives into its tenth year, its shape will transform into an 20-sided icosahedron. This process will also bestow some modicum of intelligence upon the creature, and it will now actively seek out victims - particularly if they posesses treasure. Although it usually moves from place to place on one of its score of flat faces, it can chose to roll when making attacks or other movements and does not require a slope, etc for such purposes. The icosahedron can inflict 1-6 points of crushing damage for every 8 hit points it possesses when attacking in this way. Normal or rolling attacks will also require a saving throw versus paralyzation or the creature touched is anaethetized for 4-40 melee rounds. It will also inflict 2-12 points of damage per melee round when surrounding and digesting its victim.

As is the case with their other gelatinous forms, icosahedrons sweep up metallic and other items as they move around and so can contain treasure types J, K, L, M, Q, as well as potions, daggers and similar items. As they are wont to retain certain forms of treasure, there is a 40% chance that an individual will contain types R and U. This makes them somewhat more visible, although the treasure tends to pool towards the lower half of their bodies.

Icosahedrons can be hit by all forms of weapons, and attacks by fire have normal effects. They are unaffected by cold unless they fail their saving throw, in which case their movement rate is halved. Electricity, fear, holds, paralyzation, polymorph and sleep-based attacks have no effect upon them.

Description: these creatures are large 20-sided masses with rounded edges. Although somewhat hard to see, their movement may be discerned when the creature is rolling as light is reflected by one or more faces. Icosahedrons are attracted to gold, jewels and other precious items and will seek to attack any creatures which possess them.

The Life-cycle of the Gelatinous Cube

Some creatures from the Monster Manual interest me more than others, and sometimes it's fun to wonder if they have some other form either earlier or later in their life-cycle. This got me thinking about whether this gelatinous monster only has a cube form for part of its life and, if so, would it perhaps have other shapes at some other points in time. As the cube is the same shape as a d6, I thought it'd be interesting to add other dice shapes to the mix and use them as the basis for these other forms.

This life-cycle is divided up into distinct phases: hatchling, cube, dodecahedron and icosahedron. Cubes are the most common type found in dungeons and other underground places and the creature spends most of its life in that form (I won't, of course, provide a description and stats for the cube). I'll also add in two extra creatures related to these gelatinous forms, perhaps to add a little more colour: a mysterious and very rare 'Orange Octahedron', and massive creatures called 'The Mother of All Cubes' - although they may be the stuff of legend...

The cube gains more sides as it goes through its life, and of some stages last longer than others. So:

- if a cube survives 30 years, it becomes a 12-sided dodecahedron. 

- if it subsequently survives 10 years in dodecahedron form, it transforms into a 20-sided icosahedron. 

As it gets older, the life-cycles get shorter – the trade-off being that it also gets more intelligent and becomes a more active predator. Stats and descriptions for the 12- and 20-sided versions will feature in an upcoming post.*

What I've written below could be seen as slightly tongue-in-cheek, or could be played completely straight. Either way, hopefully it might give your players something to figure out and/or fight against. As with my other creature designs, the stats and descriptions are written up in 1E AD&D format, but should be easy to convert to your preferred system. I'll add to this series in further blog posts.

GELATINOUS HATCHLING

  

FREQUENCY: Uncommon
NO. APPEARING: 3-18
ARMOR CLASS: 6
MOVE: 8"
HIT DICE: 2 hit points
% IN LAIR: Nil
TREASURE TYPE:  See below
NO. OF ATTACKS: 1
DAMAGE/ATTACK: 1-3
SPECIAL ATTACKS: Paralysation, surprise on 1-2 (if encountered outside of hatchling cocoon)
SPECIAL DEFENSES: See below
MAGIC RESISTANCE: See below
INTELLIGENCE: Non-
ALIGNMENT: Neutral
SIZE: S (1-2' tetrahedron)
PSIONIC ABILITY: Nil
         Attack/Defense Modes: Nil

Once every other year, a gelatinous cube will produce young in the form of hatchlings. A small blister will appear on the exterior of the cube and this will become detached as the creature moves from place to place. The resulting coccon will appear to be a large semi-transparent mass attached to a wall or other surface by various stringy tendrils. Closer study of this mass will show the hatchlings moving around inside, and anyone striking or puncturing its somewhat fragile shell will suffer 1-3 points of damage as it bursts and showers them with the liquid it contains. If undisturbed, the blister will rupture naturally after 3 days, and 3-18 fully-fledged hatchlings will break out and begin scouring for food. They remain in this form for 3 months, after which they hide in some dark, out of the way place and transform into their larger cubic form.

Hatchlings are only particularly dangerous if encountered in large groups, or if a number of them encounter sleeping adventurers. Coming into contact with a hatchling will require a saving throw versus paralyzation or the creature touched is anaethetized for 1-8 melee rounds. The hatchling will then attempt to digest some part of their victim, inflicting damage as it does so. Their bodies are not particularly adept at picking up solid objects, so their treasure will usually consist of nothing heavier than a few copper pieces.

Hatchlings can be hit by all forms of weapons, and attacks by fire have normal effects. They are unaffected by cold unless they fail their saving throw, in which case their movement rate is halved. Electricity, fear, holds, paralyzation, polymorph and sleep-based attacks have no effect upon them.

Description: hatchlings resemble transparent tetrahedrons, altough with somewhat rounded edges. After leaving the cocoon they are semi-transparent for several hours, and after that time their apparent opacity is patchy and noticable in certain lighting conditions.
