The Zerg

A collection of Monsters for D&D 5E based on and adapted from the Starcraft Zerg

Zerg Larva

The creatures most similar to the original Zerg insectoids are the Zerg Larvae. Each Larva contains within it the genetic makeup of every other Zerg strain available to the Hive. A young Hive will have only the genetic codes for the most basic of Zerg strains, such as the Drone, but as the Hive grows and develops new structures, the Larvae can expand its library of genetic strains. With a command from the Overlords, Larvae will enter a pupal state and begin the metamorphosis into whichever strains the Hive requires

The Drone

The original Drone organisms were initially inducted into the Swarm to serve as resource gatherers. Engineered with the Larvae’s ability to break down their own genetic code, drones can transform themselves into rudimentary Zerg structures. These structures house and nourish larva awaiting their metamorphosis, hold and sequence collected genetic samples, facilitate restructuring of strains and guiding the evolution of the swarm, and serve as mobile defensive structures for a hive or other important locations. A mutating Drone needs creep to provide nourishment and biomass to support its new form. Like Larvae, Drones are controlled by the Overlords, who monitor their progress through a type of instinctive telepathy. Drones are single-minded about their tasks, diligently working even in the face of raging combat and the possible destruction of the Hive

Stomp. Each creature adjacent to the Ultralisk must succeed on a DC 18 Dexterity saving throw or be knocked prone.

Tissue Assimilation. The Ultralisk makes an attack with its Kaiser Blades, regaining hit points equal to the amount of damage dealt.

Noxious Strain (Costs 2 Actions). The Ultralisk emits a noxious cloud of poisonous gas in the area directly around itself. Each creature adjacent to the Ultralisk must make a DC 18 constitution saving throw, taking 14 (4d6) poison damage on a failed save, or half as much damage on a successful one.
