I finally made it to level 70 and am trying to do the 3rd level advancement from Cleric to Priest. I talked to Roberia in El Nath and then Grendel the Really Old who told me to go to the door place to fight him. I went to the Door of Dimension at the Forest of Evil II with all the Maladies, but it just keeps giving me the message "You see no reason to approach the Door of Dimension" when i double click on it! Am I doing something wrong? Thank you!
There are 5 different Doors of Dimensions. Read Grendel the Really Old's text again and you'll find that it's not the one at the Forest of Evil II.
