Special Abilities

Cling (Ex)

If a creature leaves an army ant swarm's square, the swarm suffers 1d6 points of damage to reflect the loss of its numbers as several of the crawling pests continue to cling tenaciously to the victim. A creature with army ants clinging to him takes 3d6 points of damage at the end of his turn each round. As a full-round action, he can remove the ants with a DC 17 Reflex save. High wind or any amount of damage from an area effect destroys all clinging ants. The save DC is Dexterity-based.

Consume (Ex)

An army ant swarm can rapidly consume any creature it swarms over. Against helpless or nauseated targets, an army ant swarm attack deals 6d6 points of damage.

  The notoriety of the army ant swarm is well earned. Constantly on the march, a hive of army ants is capable of eating anything that gets in the way of its unabating swath of destruction and ruin. These ants are known for their relentless and organized attacks, leaving behind a trail of devastation in their wake. They are also notorious for their ability to strip an area of all its resources, leaving nothing but barren land behind.
  The army ant swarm is a force to be reckoned with, as they can easily overpower and consume much larger animals. Their sheer numbers and ferocity make them a formidable opponent, and their coordinated movements make it nearly impossible to escape their grasp. They are also known for their nomadic lifestyle, constantly on the move in search of new sources of food.
  Despite their destructive nature, army ants play an important role in their ecosystem. They help to control the population of other insects and serve as a food source for many animals. However, their aggressive behavior and tendency to invade human settlements have made them a nuisance and a threat to agriculture.
  The army ant swarm is a fascinating and fearsome creature, with a reputation that precedes them. Their relentless march and insatiable appetite make them a force to be reckoned with, and their impact on their environment cannot be ignored. Whether admired or feared, the army ant swarm will continue to roam the forests and plains, leaving behind a trail of destruction in their wake.
