Physical Traits: Oozekin exhibit a diverse range of sizes, generally falling into the categories of Small or Medium. Their gelatinous bodies allow them to flow and mold through spaces as narrow as one inch, giving them unparalleled maneuverability in the labyrinthine tunnels of the Underdark. While their forms lack a rigid structure, their innate connection to the elemental essence of ooze grants them unique advantages.   Adaptability of Form: Oozekin possess an amorphous form that grants them a heightened ability to evade restraint. They can slip through tight spaces effortlessly and enjoy advantage on saving throws against being grappled or restrained. This adaptability also extends to their immunity to the effects of being restrained, reflecting their inherent resilience against physical constraints.   Tremorsense and Ooze Nature: Accustomed to the perpetual darkness of their subterranean home, Oozekin navigate the world through tremorsense, allowing them to detect vibrations in the earth. This sensory ability provides them with a precise awareness of their surroundings, making them adept at sensing movement and activities in their proximity. Their ooze nature renders them immune to the grappled and restrained conditions, and intriguingly, they do not require conventional sustenance. Instead, they absorb moisture to survive, making them well-suited to the subterranean environment.   Society and Activities: Oozekin communities are often found in the recesses of the Underdark, engaging in activities such as mining precious gems and metals. However, their mischievous nature may lead them to cause havoc for neighboring races, either as a form of entertainment or to assert dominance. Their adaptability and unique abilities make them valuable allies or formidable foes in the subterranean landscapes they call home.   In the depths of darkness, the Oozekin carve out their existence, a testament to the resilience and diversity that thrive in the mysterious and perilous depths of the Underdark.  

Subraces:

The Oozekin society is further diversified by two distinct subraces: the Gelatinous Kin and the Shadow Slime.   Gelatinous Kin: Agile and corrosive, the Gelatinous Kin showcase enhanced dexterity, allowing them to slip away unscathed from damaging effects. They also possess the ability to secrete a corrosive substance, making them formidable in both exploration and combat.   Shadow Slime: Endowed with charisma, the Shadow Slime can effortlessly blend into shadows, becoming invisible at will. Their umbral affinity grants them resilience against fear, making them adept at navigating the darker corners of the Underdark.
