I know, that Crustacea Gigantica has quite a lot of spawn places among Tibia, like Treasure Island or Seacrest Grounds west from Rathleton.
How about Calassa?

After what time Crustacea Gigantica appears on Calassa counting from the last kill?
What is more, please tell me how much time after the 1st spawn on the south spot I can check her on the northern spot?
