Ravager

"They fire bile from their backs. I say that counts as poop. Silva says it's puke. The debate rages on."

- A Dominion marine

The ravager is a zerg artillery unit (evolve from roaches) introduced in Legacy of the Void.

Overview
Ravagers stand almost twice as tall as a terran wearing CMC armor, and hardened bone spikes portrude from its back. As an evolution of the roach, the ravager has developed a larger frame to store quantities of fiery fluid in its back. The ravager can rapidly discharge plasma at ground targets, or launch a gob of corrosive bile in a parabolic arc. This projectile is slow, best used against stationary targets, but can destroy protoss force fields. This mortar-like ability is slow moving however, and ground forces can move out of the way in time. The Dominion has theorized that this ability was evolved to aid the ravager in assaulting entrenched positions.

Game Unit
Ravagers are stronger than roaches. However, their effectiveness heavily relies on player micro due to their corrosive bile ability.

Abilities
Corrosive Bile: A mortar-esque ranged attack which strikes a small area after a short delay. Can attack both air and ground units. Mobile units, especially air units, can easily dodge the attacks. Immobile units, such as s in Siege Mode, buildings, or other units ensnared by Fungal Growth, will easily fall prey to this. The ability can also destroy sentry force fields. Does area of effect damage. Area of impact is chosen by player. Has a range of 9.

Development
An upgrade existed that allowed the range of corrosive bile to be increased to 13. Costed 100 minerals and vespene gas. Required a lair.
