Devourer

The devourer was the anti-air aspect of the zerg mutalisk, a heavier flying strain that the Swarm deployed to dominate the skies against enemy aircraft. It was slower than the mutalisk from which it descended, but faster and more resilient than the guardian, the mutalisk's anti-ground counterpart. Its defining weapon was a corrosive payload of acid spores.

Origin and role#

Like the guardian, the devourer was a specialized morph of the mutalisk. Where the guardian gave up its air defenses to bombard the ground, the devourer turned fully toward the sky, becoming a dedicated hunter of enemy aircraft. It was slower than a standard mutalisk but considerably tougher, and tougher and faster than the guardian, which made it the durable anchor of a zerg air formation.

Acid spores#

The devourer's attack carried an additional effect beyond its direct impact: it flung globs of acid that attached corrosive spores to anything they hit. A target afflicted with spores had its rate of fire slowed and took additional damage from every attack that followed, with the effect compounding as more spores accumulated. As many as nine spores could cling to a single target at once before they eventually dissipated.

This made the devourer far more valuable as a support strain than as a lone attacker. The fast, bouncing strikes of accompanying mutalisks benefited enormously from a target coated in spores, letting a flight tear through heavily armored aircraft far faster than it otherwise could. The devourer's own attack, by contrast, fired slowly and traveled slowly through the air, and if it moved before its glob of acid struck, the shot was wasted. That sluggishness left the devourer exposed to fast hit-and-run attackers, so it fought best as the resilient core of a mixed air swarm rather than on its own.
