Monsters: Modrons

Monsters: Modrons

Now that I'm done revising the old monsters, let's make something new. The modrons have been suggested to me, and let me tell - they aren't going to be easy to stat up. First of all, who are the modrons? In the D&D cosmology, they are the paragons of order, the lawful counterparts to the celestials, fiends, and slaadi. If you're used to D&D 3.5, then you might not even know that they exist in that edition, as they are well hidden. First, they appeared in the web enhancement for the Manual of the Planes, and some of them later got updated in Dragon Magazine #354. There's also a fourth-edition article about modrons in Dragon Magazine #414. The lore has changed a little bit between the different editions, but I will try to combine most of the bits into something more or less coherent.

There are fourteen main types of modrons, or fifteen, if you count Primus, their leader, but a few of the fourteen main types have secondary variants. In terms of body plan, abilities, and mentality, the modrons are different, so let's start with their common qualities.

First of all, the most interesting fact about the modron physiology is that they are the so-called living contructs that combine organic and clockwork parts. There are multiple different ways you can go about it, but I decided to do the following: Doesn't Breathe [20], Doesn't Eat or Drink [10], Doesn't Sleep [20], Immunity to Metabolic Hazards [30], Injury Tolerance (No Blood, Unliving) [25], Slow Healing 2 [-10]; Temperature Tolerance 6 [6]; Unaging [15]; Vacuum Support [5]. Thus, unlike the normal constructs, the modrons do heal naturally, but very slowly, and despite being Unliving creatures, they do possess the vitals hit location. Also, they do possess the FP score, unlike proper machines.

    Even though I gave them Doesn't Eat or Drink, the modrons have to imbibe a special psychomorphic substance that can be found on their native plane of Mechanus. They have to do it once every three months, or else they begin to degrade. This is Dependency (Psychomorphic Substance; Rare; Seasonally) [-10].

    Let's do the senses. I gave the modrons Dark Vision [25], No Sense of Smell/Taste [-5], and High Pain Threshold [10]. Their lore says that all of them lack the sense of taste, and most of them lack the sense of smell too, so that'll be the baseline. They do possess tactile sensors, but they can easily disable the feeling of pain, which effectively is equivalent to High Pain Threshold.

    Modrons are covered in rigid armor, but the coverage depends on the modron type in question. Thus, they will have DR, but I will give this DR a Nuisance Effect to represent the possibility of striking unarmored fleshy parts. This integral armor plating is also magnetic, so I will give them the Affected by Magentism quirk. It seems to me that some modrons also have glass lenses over their eyes, and that'll be Nictitating Membrane. Since the limbs always have at least DR 3, I will also give the modrons the Striking Surface perk to increase their punching and kicking damage, as if they were using brass knuckles.

Modron mentality is more difficult. First, they are beings of order and logic - I went with Indomitable [15]; Immunity to Mind Control [30], Unfazeable [15], Clueless [-10], Low Empathy [-20], and No Sense of Humor [-10].

    The main feature of the modron psyche is that they are completely subservient to modrons of the immediate superior rank. At first, I wanted to go with a limited version of Slave Mentality, but that wouldn't work, as they'd have no initiative at all without an order from their superiors. Instead, I went with Extreme Fanaticism (Modron Hierarchy) [-15].

    There's another gimmick. Modrons are completely unable to comprehend the existence of modrons that do not belong to the adjacent ranks. Modrons of other ranks are just incomprehensible beings of order to them. I went with Delusions (No modrons outside the adjacent ranks exist) [-5], because it makes communication and chain of command difficult.

    The modrons do have a sense of self and their own personalities, but they find the modronkind in general more important. Thus, I went with Selfless (6).

    Other modrons, depending on their rank, might have other disadvantages, such as Workaholic [-5], Incurious (6) [-10], etc.

Finally, we should not forget that the modrons are an embodiment of order. I will give them the Axiomatic Touch perk and Vulnerability (Anarchic Weapons, x2) [-10]. The perk is based on the Holy Touch perk from GURPS Dungeon Fantasy 20: Slayers and makes all natural weapons count as axiomatic weapons for the purpose of vulnerabilities.

So, let's get to the modrons themselves, starting from the bottom of the rank table. First, we have the monodrone and its messenger monodrone variant. They are small, roughly spherical, have one eye, and are barely intelligent. To represent their utter focus on the task at hand, I gave them Single-Minded [5], Incurious (6) [-10], and Workaholic [-5]. Their armor plating seems to only have a gap in front that can be targeted at -6. Since they have their faces on their torsos, I gave them Injury Tolerance (No Head and No Neck). Messenger monodrones have no arms, but have wings instead.

Duodrones are next. While it seems that they have heads, I believe that this is closer to a segmented torso, as the arms are coming out of the top part, and both parts are of the same size, so I will keep Injury Tolerance (No Head and No Neck). Duodrones are stonger, slightly smarter, but less agile. Since their attention is not as focused, I increased the self-control number for Incurious from 6 to 9.

The tridrones finally graduate to being SM+0 creatures and having human-tier intelligence. They look like a d4 upside down with six legs and three arms. I gave them Extra Arm 1, Extra Legs (Six Legs), and Extra Attack 1.  Since the arms are all primary, I also gave the tridrone Ambidexterity. They have one eye and one mouth on each side. This means Extra Mouth 2 and 360° Vision, but with No Depth Perception, as they cannot perceive something with two eyes at the same time. They seem to be less fully covered in armor, so I decreased the penalty to target the fleshy parts from -6 to -4, and removed the frontal attack requirement. In terms of mentality, I increased the self-control number for Incurious from 9 to 12.

Quadrones are cube-shaped, but they have sensory organs on all sides, so they retain 360° Vision. They are as armored as duodrones and have armored lenses. They are as intelligent as humans, and not as focused as tridrones, so I removed Single-Minded and Hidebound. Some quadrones have vestigial wings, but some of them have fully functional wings.

Now, let me digress a bit. A modron of any rank can go rogue for one reason or another. Such modrons are hated by the normal modrons and are exterminated on sight. However, some modrons realize that they have gone rogue and petition to be exiled instead. Such modrons are transformed into a creature that resembles a quadrone and are set free. They are cut off from their psychomorphic energy source and are removed from the modron hierarchy. As such, they lose some advantages, but they also lose many disadvantages. For some reason, they only have two eyes, unlike the normal quadrones, and they also get the Combat Paralysis disadvantage. In D&D, they were supposed to be a playable character race, but in GURPS, they end up being way too expensive.

Pentadrones are the highest-ranked modrons of the base caste. They look like clockwork starfish on five legs. Each arms of the starfish has an eye and a mouth. For the purpose of mechanics, I will treat each arm as an actual arm with Extra-Flexible and No Fine Manipulators. The number of mouths is increased to four. I decided to give them thicker armor in addition to large size and ST bonus. Pentadrones also possess an ability exude a cloud of paralysis gas or use the gas as a reactive thruster.

    Arm Slam (14): thrust 2d-1 crushing (KYOS: 3d-1 crushing), Reach C-1.

    Armor Plating: The pentadrone is covered in metal plate armor that provides DR 5. However, when attacking the torso or arms, a character can strike the unarmored fleshy parts at -6.

    Gas Thrust: The pentadrone can emit gas downwards to propel itself in the air. It can fly with Air Move 6 with a flight ceiling of 10 yards, and each second of flight costs 1 FP.

    Paralysis Gas (12): The pentadrone may emit a stream of paralyzing gas. This is a cone attack that uses rules from Area and Spreading Attacks (pp. B413-414). The cone is 1-yard wide and has a length of 10 yards. Each use costs 2 FP. It is possible to make the cone wider by using the rules from Cones of Power (GURPS Dungeon Fantasy Monsters 4: Dragons, p. 10). Creatures who breathe the gas must roll against HT or be paralyzed for 2 seconds times margin of failure. After that, the subject is stunned (p. B420) and may roll vs. HT once per second to recover.

Now we're done with the base modrons. The high caste of the modron society is the hierarch modrons. The higher the rank, the more humanoid they are, and they possess many different abilities. The lowest hierarch modron is the decaton that looks like a sphere on two legs with ten eyes and ten tentacles, and one mouth on the top. For hierarch modrons, I decided to remove Incurious and decrease Slow Healing 2 to Slow Healing 1. Finally, they can communicate telepathically via the Telesend advantage and have some spell-like abilities - Command, Minor Healing, Repair, and Teleport.

Nonatons are next on the rank ladder. They have cylindrical bodies with two eyes and two mouths. Yet again, I have to return No Depth Perception. They have three legs and nine tentacles. Unlike the decatons, they cannot fly, and their set of spell-like abilities is aimed at detecting alignment auras and planeshifting instead of mending wounds.

Octons are very similar. In terms of the body plan, they have a ring that houses eight tentacles instead of nine, and they have two legs. Their spell-like abilities are fewer in number, and for some reason they get Static (Psi). I don't mind that.

Septons is where hierarch modrons become more or less humanoid. They have a proper head and face now, but still no neck. We abolish the all-around vision, lose the ability to fly, but retain psionics immunity. Finally, septons get a nose! So, while they still have no sense of taste, now at least they can smell. In addition, septons get a constantly active ability to see magic auras.

Quartons lose their prehensile tail, become faster fliers, lose their aura sight ability, and gain an ability to project force walls. Technically speaking, all the hierarch modrons were supposed to have this ability, but I decided to reserve it for the high rank ones.

Tertians have only two arms and a tail that ends in a mace-like growth. They are more intelligent than the quartons, but have lost their ability to fly.

The secundi lose the tail, regain the ability to fly, but without wings this time, and expand their array of spell-like abilities with something you've already seen before. They are at the top of the ladder, second only to Primus, the quasi-divine entity that rules the modrons.
