No matter which one I enter, I invariably get stopped cold after
being made well aware that there is more to see.
The conjurors' dressing room, the watch tower, the tower of ordeal,
Hell, even the newbie training rooms. It is painfully obvious that
there is something hidden, but whether a password needs to be
spoken, or a spell to be cast is unclear.
For example, in the tower of ordeal there is sign which says
'show invisible!'. Well, I cast show invisible, and nothing happens.
Am I using the spell wrong? How is it supposed to work?
And why the Hell does a dungeon populated with kobolds and orcs
require a fairly specialized prayer to enter?
So I am asking for spoilers - how does one advance in the four
dungeons listed above? I want to see what the solution is, before
I decide to put more effort in solving these maps, or conversely
decide that they are not worth bothering.
