Silver armored spider F.O.Es found in the eighth and ninth floors of Clock Tower. They jump towards prey caught in the webs, but can only jump three times towards them, and can only move to another web each time it jumps. They will not jump to webs if their path to that web has been blocked. Otherwise they will stand guard where they are unless their prey walks into another web. The Tangled Thread it drops is one of the materials required to create everyone's ultimate weapons.
The Capturer is incredibly similar to the previous F.O.E encountered within the dungeon, The Watcher. The Capturer's magical prowess exceed those of The Watcher, but the real primary difference between the two spider F.O.Es is its access to Mahamaon and Stone Mist. Attempting to stave off these techniques, as well as Mamudoon, is simply needlessly demanding. Instead, potential challengers should come prepared with Homonculi and Ma Patra gems.
