  • Travel to (F-7) or (F-9) of Castle Zvahl Baileys (S).
  • Attack the Zvahl Fortalice located at the top of the stairs in either location. It won't fight back or spawn any monsters.
  • The mission is complete when the Fortalice is defeated. You will receive the EXP reward immediately.
  • Speak with Hieronymus to complete the Ops and receive your Allied Notes.


  • There are a number of truesight mobs on the way to Castle Zvahl Baileys (S), as well as mobs that aggro to both sight and sound.
  • Defeating a Zvahl Fortalice reduces the Fortification by -2
  • Respawn Time about 30 minutes
  • No monsters seemed to get close enough to the Zvahl Fortalice to cause any problems. (Except the Elementals on the first two Zvahl Fortalices, if you use magic)
  • Caution advised as the nearby Demons may occasionally aggro!


Allied scholars have determined that an unseen barrier is preventing direct damage to the walls of Castle Zvahl, greatly impeding our siege effort. Join the mercenaries of the Cobra Unit to seek out and eliminate the source of the obstruction.

Unit Requirement: 1
