Dire Ant

Dire Ants are the hulking footsoldiers of their insectoid hivemind. Ranging in size from wolf to siege engine, the creatures are driven by scent and instinct, and they communicate through the emission of complex chemical signals, as their low-resolution vision is limited to a melee space. Dire Ants have lightweight exoskeletons with a large cross-section of muscle mass that allows them to carry up to fifty times their own body weight. When threatened, the Ants emit a scentless pheromone spray—a barely perceptible mist that expels from gland-like vents on their sides—that marks targets as enemies to alert the hive. The creatures do not have individual identity; they think and fight as one, and an encounter with a sole Ant likely means more are coming.

Dire Ants are formidable on their own, but through the coordination of the hive they have the potential to overwhelm parties with sheer numbers. Accordingly, lone ant discovered by the PCs might flee after spraying them with its pheromones so that the hive can later mob them in calculated waves. GMs can push tactical thinking by introducing environmental obstacles alongside the Ants such as collapsing tunnels or hive terrain that’s full of natural traps. Smart PCs may realize that steering clear of the Dire Ant’s pheromone spray and covering themselves with the body parts of fallen drones may prevent detection by the hive. Surprise players with colossal, psychic, undead, or antimagic variants; their diversity in form is always a consequence of the nature of the hive’s habitat.
