Creeping Cone Swarm

Caustic fluid seeps out from the scales of these sluglike cones, which spawn in unsuspecting hosts until they're mature enough to seek a place to root. Moving in writhing swarms that seek a habitat flush with prey, creeping cones spread Ayrzul's Blight when destroyed, but leaving them to grow unchecked poses a great risk to other creatures.

The Plane of Wood contains many unique ecosystems formed around species of wondrous trees; when Ayrzul's Blight mutates one of these trees rather than killing it, it can have a cascading effect on the tree's biome. Multiple species often mutate in tandem, becoming warped mockeries and a vector for Ayrzul's Blight. These "blight bonded" creature families are parasites and predators and typically form twisted symbiotic relationships.
