Symbionts are custom-grown plant creatures tailored to serve specific purposes, like living tools. There are myriad forms of symbionts on Kir-Sharaat that serve mundane purposes, like mobility enhancing exoskeletons to assist erahthi who possess difficulty walking or lifting heavy objects, communication symbionts that can relay messages, even clothing that sizes itself to fit its wearer and protects against parasites and pests. This section focuses on combat-oriented symbionts designed during the Century War.

Though the erahthi created symbionts first, their widespread use is now found beyond the boundaries of Kir- Sharaat and organizations across the Aethera System traffic in the secrets of their creation. Creatures of all species can create plant symbionts, and some have even begun to experiment with creating symbionts of other creature types, like aberrations and elementals. Symbionts are created in special laboratories and each have a monetary cost associated with them like magic items.

Erahthi have created a wide variety of living plant symbionts to take the place of typical equipment, and these symbionts are often sought after as curiosities or specialized weapons. A plant symbiont can be affected by spells that target plant creatures, though it is mindless, incapable of independent action, and has no ability scores other than Constitution (which is always equal to its item level). It is subject to poisons and diseases, though it does not need to breath and is always protected as well as a creature with active environmental protection from armor. If it is forced to make a saving throw, its save bonus is always equal to its item level. If it suffers a condition that would normally cause it to take a penalty to attacks, damage, save DCs, saving throws, or AC those penalties apply to any attack or effect created with it. Plant symbionts “eat” by absorbing part of the charges or fuel (or energy from some other form of ammunition) when fired. They do not sleep or breathe, cannot communicate in any way, retain all plant immunities (including saving throw bonuses), are immune to pain effects, and are mindless.

If damaged, a plant symbiont can regain Hit Points from effects that restore Hit Points to living creatures, such as a mystic cure spell, and it regains a number of Hit Points equal to its item level each day. You can use the Life Science or Medicine skill instead of Engineering to repair a living weapon.

In addition to the relatively helpless normal plant symbiont, there exist advanced plant symbionts which can transform into an independent form and back as a full-round action. While in independent form, an advanced plant symbiont acts a drone with an effective mechanic level of its item level -3, save that it is considered a plant rather than a construct for the purpose of determining effects and possesses no feats or mods save for initial mods gained from its drone chassis. An advanced plant symbionts’ chassis is determined when it is created and items of lower than 4th level cannot be made into advanced plant symbionts. The owner of the advanced plant symbiont may control the advanced plant symbionts as if they were the drone’s master.

A normal plant symbiont version of an item costs 10% more than normal. An advanced plant symbiont version of an item costs 50% more than normal.

The energy protection symbiont attaches its root system to the host’s chest. From a bulb shaped stem, hundreds of vines wrap around the host’s entire body, including membranous leaves that cover the host’s eyes, mouth, and ears. Depending on the type of energy the symbiont provides protection against, it takes on a certain hue: deep green or black for acid, pale blue or white for cold, orange or red for fire, and yellow or deep blue for electricity.

The energy protection symbiont saw some commercial application prior to the Century War, as the erahthi would use it when working in dangerous environments. During the war, production of the energy protection symbiont increased, particularly fire-resistant symbionts. Only the most crack erahthi soldiers wore the symbionts, often finding themselves in the thick of the fighting. After the war, as the erahthi began exploring the Aethera System in greater numbers, the energy protection symbionts proved valuable in a host of new environments. Additionally, the other races of the Aethera System desired the symbionts as well, driving up demand for their creation in markets across the system.

Detached, the energy resistance symbiont stands as tall as a large dog and moves on four trunk-like roots. Its central body is the bulb-shaped stem, engorged with the energy produced within its root system. Though designed to protect and use one type of energy, the energy protection symbiont shows no aversion when confronted with opposite elements. It does, however, tend to gravitate towards environments hosting the type of energy for which it was designed.
