Full: Rurik's wait to open the exit door.
Concise: Rurik's wait to open the exit door.
- Knock is the Monster skill that Prince Rurik uses to open the gate during the final stage of the Ruins of Surmia (mission).
- With an activation time of 20 minutes, this is probably the skill with the longest activation time in all the campaigns of Guild Wars.
- This skill does not actually open the door. It is a "dummy" spell just to provide a reason for the delay of the opening. The only way for the door to open is for you to kill every Charr.
