Sessativa does not need to use a spell to tell these items are magical. She can feel the magic in them. She will have to use a identify spell per item to tell what it is exactly. You can always use the items or put the items on. That would be your choice.
"Yes, best to keep them off since we're already dealing with one curse," Sessativa says shakily, unsure of Drugan's condition.
She grabs Durgan's hand and waits for Zork to pass by, before following up the stairs.
You get to the top of the stairs and see a door that is shut. It has no lock that you can see. When you open the door you see a very rich appointed sitting room. There are shelves that may have one time held books along with a desk to one side with a nice padded chair in front of it. There are also two other chairs in the room facing the desk. The room is spotless and there is nothing you can see in the room besides the above items. It is like someone cleaned out the room except the shelves chair and desk. There is another door behind the desk.
Zork sends his dog to check around first and then he will do the same ending up at the door to open it if nothing else is found.
Zork comments, "Its as though part of this tower is the opposite of the other."
"I hadn't noticed," Sessativa says.
"Me neither," Durgan quips and chuckles.
She briskly walks around the room, wand checking for any residual magic, before continuing through the door after Zork.
"Nice find" says Zork as he awaits her next move. "We need to move on if we are to catch whomever you think we are following."
