The basic nature of a non-cyriss cerebral matrix is perfectly understandable given that cortex’s have to be so large to achieve any great deal of sentience. But considering the increase in intelligence displayed by servitor swarms in the Liber Mechanika, there should be some way of enhancing how smart you can make a servitor or matrix run device.
The first idea for a ruling was that you could conduit together up to four cerebral matrices in series, each having an int of 2 combining to a max int of 8. Which is an improvement, but still puts it below the power of a cyriss swarm or the most powerful cortex’s. Balancing this with the advance in cortex technology is that the ‘thinking’ of such a device is effectively by committee. So its reactions are far slower than a steamjack of similar intelligence, making it more ponderous and robotic overall. (minus to initiative & reflex saves equal to number of matrices conduited, cannot perform swift or immediate actions.)
Conduiting two Cerebral Matrices: 2000gp
Conduiting three Cerebral Matrices: 3000gp
Conduiting four Cerebral Matrices: 4000gp
The second plan was to expand on the Task Plate idea that privateer press sort of left hanging, aka introducing devices you added on to a cerebral matrix to give it additional capabilities at additional weight and cost. The Dragonmech books provided a large resource of ideas for these sorts of devices, (as well as some interesting ones for mechanika, but that’s another story). So these act as small additional mechanika that you can conduit onto a matrix, the actual info for each can be found in the Dragonmech book ‘Steam Warriors‘. Cyriss Tech additions require the Feat to make and install into a matrix. Voltaic Tech items require an electrical power source, most likely from a stormchamber. All additions require the ‘Craft: Cerebral Matrix’ feat to create and install.
Bloodhound: 350gp | 4 lb. [A bloodhound allows the device to detect scents. Range of detection is 30ft, double if the scent's source is upwind or half if it is downwind. Strong scents can be detected at twice the normal range, and overwhelming scents at triple range. A bloodhound can only sense the general direction of a source except when within 5ft, at which point it can be more specific.] <cyriss tech>
Discriminator: 350gp | 4 lb. [A discriminator is a heavy metal orb containing a tightly packed series of adjustable fluid-logic valves that can hold information about people and creatures. The most common model will use this information to discriminate friend from foe and react accordingly. Each additional person above the creator to be designated a friend must be taught with a jack handling check and cannot exceed the devices intelligence.]
Identifier: 500gp+ | 10 lb. [An identifier can ID almost any natural, nonmagical substance placed within its analyser tray. It can break down foods and poisons to their component ingredients and point out the source of a particular flavor or toxin. It acts as if it has 20 ranks in the relevant Knowledge skill to identify the substance, the sample is destroyed during identification. Building an identifier requires a full six months of work, and an endless variety of natural samples, as each new sample requires a jack handling check. An identifier can only ID a material it has processed this way.] <cyriss tech>
Metal Ear: 35gp | 4 lb. [The metal ear is an artificial listening device that can hear about as well as a normal human ear, and transmit those vibrations to a connected device.]
Navigator: 50gp | 2 lb. [The navigator is a small box of clockwork drums that can detect and keep track of distances moved and turns taken. It will 'remeber' any path it travels up to two miles. A single navigator can store any number of paths at a time, provided to total distance is not more than two miles. Navigators can be stacked to increase this distance. A navigator combined with an automated quill could produce maps on paper for example.] <cyriss tech>
Noisemaker: 300gp | 3lb. [A noisemaker is a wax cylinder conduited to a small ionic coil and paper cone arrangement. It can be used to record and replay noises it receives from a connected device.] <voltaic tech>
Optical Orb: 275gp | 2 lb. [A small glass eyeball or optical tube which can perceive the world around it and revolve to follow moving objects. The images are transmitted to a connected device. While it can see in colour like the human eye, it only has hardness 3 and 3 hit points, and can be easily shattered.]
Randomizer: 50gp | 1 lb. [The randomizer is a small attachment that causes one aspect of the device to be completely randomized. Elements of a device that can be randomized include but are not limited to: damage, range, direction, attack type and target. Once installed the function that is randomized cannot be changed without adding a new randomizer, however a successful Craft: Mechanika check (DC 15) can reprogram the drums to a different form of random decision.] <cyriss tech>
Ranger: 240gp [A collection of incremetal measuring slides fitted on bearings within a short barrel, the ranger acts like a small adjustable sight. Devices fitted with a ranger gain a +1 bonus to ranged attacks beyond 30ft. Multipal rangers do not stack.]
Scanner: 800gp | 20 lb. [A flat boxlike device, the scanner can detect a specific material within 100ft that has been used it its creation (minimum of 100 samples). The scanner translates the location and distance to the material to a connected device and can make a rough estimate of the quantity present. Scanners designated material cannot be changed once it is constructed. Scanners cannot be set to detect non-physical properties.] <cyriss tech>
Skill Box: 200gp+ | 1 lb. [A complex device the skill box contains multiple drums and valve arrangements that allows a specific set of coordinated movements to be recorded and stored, allowing the connected device to use a physical skill. The builder of the skill box must have at least 8 ranks in the skill to be put into the skill box. The device with a skillbox installed is considered to have 4 ranks in the skill. Multiple skill boxes of the same skill cannot be installed to provide a greater bonus. ] <cyriss tech>
Skill Recorder: 500gp | 2 lb. [This steel drum contains a tightly wrapped spool of metal sheeting that contains information punched into its surface. As a standard action, the device can provide a +5 circumstance bonus to a skill check. Each recorder is good for one skill only, only physical skills can be recorded in this manner and a device incapable of putting the skill into practice gains no benefit from this bonus.] <cyriss tech>
Targeter: 320gp | 1 lb. [A targeter is a complex arrangement of crystal tubes and processing drums which automatically acquires a target for a ranged weapon connected to the device. By itself a targeter always aims for the nearest living creature, whether friend of foe. Combined with a discriminator it will aim at the nearest hostile instead. Combined further with a scanner it can automatically pick out certain types of target. This device removes the penalties to attacks for using an unfamiliar or non-proficient weapon. The targeter cannot target anything the attached device cannot perceive.] <cyriss tech>
Timer: 30gp | 1 lb. [allows it to function at specific times or intervals.]
Trembler: 500gp | 1 lb. [A trembler allows a device to act as if it had tremorsense as long as it is in contact with the ground, or underwater.]
Trigger: 50gp | 1 lb. [A trigger allows the device to activate another device or a power when a specific set of conditions is arrived at, each trigger can only react to a single even. For example the device could be set to activate when there is motion within 10ft, if the temperature reaches a certain level, or when a door is opened.]
Vocalizer: 200gp | 10 lb. [Allows the device it is attached to to give primitive vocal feedback, its buzzing mechanical voice can only produce words, not inflections or emotions and must be taught its vocabulary with a jack handling check.] <voltaic tech>
