Deep Sentinel (Etrian Odyssey III) Edit
|Skills||Leaping Slash, Counter, Sea Guillotine|
|Resistance||Bash, Slash, Pierce|
Deep Sentinels are only encountered past the locked door on B16F, accessed during the Eldest Path ending route.
They share many of the Coistrels abilities, such as taking a counterstance, and if together with a Deep Believer, can perform a deadly attack called Sea Guillotine, which damages and may cause instant death to all party members
