In use by 2505,[1] the ravager is the result of years of twisting and fine-tuning the genome of the roach far beyond its biological limitations.[2] Ravagers stand almost twice as tall as a terran wearing CMC armor, and hardened bone spikes portrude from its back. Its eyes grant it a broad spectrum of vision.[1]
The ravager wields plasma fire both in close-quarters combat and as a wedge to crack open entrenched positions, something the Swarm has struggled with in the past.[2] As an evolution of the roach, the ravager has developed a larger,[3] heavier[2] frame to store quantities of fiery fluid in its back.[3] The ravager can launch a gob of corrosive bile from its back in a parabolic arc. This projectile is slow, best used against stationary targets, but can destroy protossforce fields,[3] and is effective against heavy units and structures. The Dominion has theorized that this ability was developed to boost the ravager's utility in assaulting entrenched positions. This mortar-like ability is slow moving however, and ground forces can move out of the way in time.[1]
Game Unit
"Now they're sending ravagers our way. Watch out for their corrosive bile."
Ravagers are stronger than roaches. However, their effectiveness heavily relies on player micro due to their corrosive bile ability.[7]
