Arcscoon's silk is legendary for its strength and resilience, creating a nearly unbreakable cocoon around it. The thorns on its body cause those pricked to hallucinate visions of strange glowing symbols all around them.
Arcscoon move by loosing sticky threads from their golden spikes, which they are remarkably skilled at doing. Though they can swing themselves into threats, most would prefer to suspend themselves high off the ground within a web of their threads.
To avoid detection by its enemies, it hides motionlessly beneath large leaves and in the gaps of branches. It is described in mythology as the Pokémon that shaped the universe with its 1,000 arms.
