Architeus is an exceptionally large Sepiid. Architeus has extra tentacles and arms. The tentacles have very sharp spikes on them, which can be detached
Architeus' tentacle spikes, when detached, begin to spread long, thin, tentacle-like strands. If one of the spikes in inserted inside a living being, it will begin to slowly clog their veins and freeze their muscles until the subject becomes fully paralyzed and eventually dies.
