Autobow

Automatic crossbows, commonly known as autobows, are Elethian-powered machines similar to crossbows, but with an automatic cocking mechanism that allows multiple shots without recocking. Autobows comprise two main constructions: the crossbow assembly that guides and fires the bolt, and the automatic mechanism consisting of the loader, trigger assembly, and force injector. Most also comprise a grip or stock, though this is not part of the core assembly, and is often modified or adjusted after creation.

Mechanics & Inner Workings

Most autobows are based off two limb crossbow designs, with a pair of horizontal limbs near the front of the assembly that bend backwards to provide tension. Unlike standard crossbows, the limbs, flight groove, and barrel are all made of metal, to ensure consistent accuracy and reduce weight. The string is typically made of high-quality sinew attached to a metal serving slider that locks into the back of the assembly frame until the trigger is depressed. The bolt is loaded and held in a closed chamber to ensure both consistent accuracy and to avoid potential damage while being nocked for long periods of time.   The mechanism comprises a number of metal clockwork pieces that load the bolt, a large metal receiver that holds the Eleth canister, the force injector, and the trigger assembly that fires the crossbow. When the trigger is depressed, the serving slider moves forward to push the bolt. As the slider moves through the bolt, it depresses a lever that allows Eleth to enter into the injector. The slider itself is attached to a block that moves against the force injector. Once the force injector reaches sufficient levels of Eleth, it releases a burst of kinetic energy that pushes the block backwards, which also moves the slider and string backwards, resetting the firing position.   Non-repeating autobows do not have a mechanism to load the bolt; rather, the operator must operate a lever after firing to grab a bolt, and push it into place. In a repeating autobow, the slider contains a notch that grips a bolt and draws it back alongside the string. However, this mechanism requires far more precise engineering, as a malfunction can rip the bolt to shreds and severely damage the action. Most single-fire autobows hold the bolts in a spring-loaded tubular integral magazine that runs the length of the action, and must be individually reloaded. Repeating autobows typically use a more advanced system with an integral box magazine fed by a stripper clip near the front of the action that can reloaded much quicker.

All autobows can be fired manually by engaging the safety on the Eleth canister to prevent Eleth entering the force injector, and using either an integral cranequin or attaching an external tool to the top of the slider. When used in this way, an autobow acts exactly as a crossbow of similar draw weight, requiring a manual draw depending on the tool used. Autobows will not fire if drawn back without a bolt in the chamber for safety reasons, as dry firing an autobow can lead to malfunctioning actions and catastrophic disassembly, and most have a manual trigger block safety that stop the trigger from being pulled back. Additionally, if an autobow has an integral cranequin, it can also be used to decock the crossbow once it is drawn back, though manual removal of the bolt is typically suggested beforehand for safety reasons.

Notes
[1] Autobows use a canister of Eleth to power their automatic capabilities. Every 20 x Shots times the autobow is fired, the canister must be replaced, which takes three seconds. The ammunition cost listed is the cost of the canister; the bolts are bought normally. Canisters are standardized in 2.5lb, 3.5lb, and 6lb variants which cannot be interchanged.
[2] Contains an integral cranequin.

Autopistols

Automatic pistol crossbows, commonly called autopistols or pistol autobows, are designed similarly to full-sized autobows, but with a few key differences due to their size. Unlike autobows, autopistols are typically built with four limbs, though six-limbed variants exist, due to the significantly shorter draw distance requiring far stronger limbs. It is fairly typical for the entire construction to be made of metal, and for the crossbow to double as a improvised club once the last bolt has been shot. Some higher quality variants can have collapsible limbs, but this is rare due to the precise construction required to ensure the limbs can lock properly.   While autobows typically use a closed chamber with a bolt that is directly struck by the string, autopistols usually use an indirect system where the string pulls a metal plate forward, which impacts the bolt and carries it forward. The bolt is still loaded into a closed chamber, but all autopistols will automatically chamber a new bolt after being fired. The most common loading system is an integral magazine set above the chamber that drops a new bolt into the chamber using gravity, but this mechanism requires thin, uniform bolts, severely affecting the accuracy and range of the autopistol, and is prone to malfunctioning. These designs tend to have a small button or lever that is hit to force the bolt into the chamber if a malfunction occurs. When the magazine is emptied, the user can individually reload each bolt from the top of the autopistol.   Repeating autopistols and high quality autopistols use a different system that loads a magazine or stripper clip at the front of the action, and uses the bottom of the strike plate to drag a bolt into the chamber. These designs typically use a sliding mechanism that extrudes from the front of the autopistol when fired to provide enough space for the bolt to be retrieved and chambered. However, this requires precise machining, and can catastrophically malfunction if the slide catches the bolt.   While most autobows have a manual cocking system, due to the high draw weight, short draw distance, and weight considerations, autopistols typically require an external cocking mechanism to prime the first round. This makes expeditious reloading of an autopistol in the field difficult if the Eleth canister is fully exhausted. Experienced users will typically count their shots, and it is common for custom-made variants to not allow firing if the Eleth canister has been exhausted.

Ammunition

Autobows and autopistols use smaller, specialized bolts compared to a standard crossbow, due to their higher velocity and requirement to fit into a magazine. Furthermore, specialized armor-piercing and expanding projectiles can be used, alongside more esoteric warhead bolts. Wooden bolts are the standard bolts assumed for any non-repeating autobow as listed in Basic Set; each bolt costs $2, weights 0.1lbs, and deals impaling damage. The action of repeating crossbows require the ruggedness of metal bolts, typically constructed as a singular piece of molded steel; each bolt costs $5, weights 0.1lbs, and deals pi damage. All the bolts listed below use metal bolts as their base; specialty wooden bolts are typically not used.  

Crossbow Bolts

Non-repeating wooden crossbow bolts cost 2$; repeating, metal crossbow bolts cost 5$.
