The devourer's attack has the additional effect of attaching "acid spores" to anything it hits. A unit affected by spores will be revealed (if cloaked), have its attack speed slowed by 1/8 per spore, and take 1 point of additional damage from every attack for every spore attached. A maximum of 9 spores may affect a target at any one time. Spores will disappear after a period of time.
