Nylocas Ischyros are part of the wave prior to the Nylocas Vasilias encounter in the Theatre of Blood. They spawn alongside Nylocas Toxobolos and Nylocas Hagios as they attempt to destroy the pillars.
- The word "Nylocas" is very similar to the hungarian word "Nyolcas", which translates to the number "eight" relating to the eight legs of this arachnid-like creature.
- The latter part of the name of the Nylocas Ischyros likely derives from the Greek term "ἰσχυρός"(transliterated, "ischyrós"), meaning "strong" or "mighty". Thus, the Nylocas Ischyros may also be understood to be a Stong Nylocas - a name likely intended to lend credence to its lore and the source of its fortitude with melee.
