Symbiont, Living Armor

A humanoid mass of leaves, vines, and roots stands with a hunched posture. Its hands end in wicked claws and its head is little more than an oversized thorny maw.

A living armor symbiont appears as a mass of writhing, leafy vines. When it bonds with a host, via the roots embedding themselves into the host’s chest, the vines wrap around the host, extending to the upper arms and legs. The vines are bred to be extra strong, increasing the host’s natural strength as well as providing protection from damage.

Detached, a living armor symbiont takes on a disturbingly humanoid form, its vines entwined around its roots to form legs, two arms formed from dozens of vines, and a pair of giant leaves forming a snapping maw for the head. It lurches forward with a shambling gait, dozens of vines and roots working together. In combat, the armor symbiont closes in to melee to make use of its liquefy ability.

The cost of a living armor symbiont made it too impractical for common soldiers during the Century War, so it was often used by elite soldiers and high-ranking military officers who were worth the costly investment. This symbiont’s effectiveness makes it a popular item not only with the erahthi military but also by private security forces and militaries on other planets.
