"What's going on?" Daniel frowned when he saw the notification and tried again to exit the dungeon, but no matter how many times he attempted it the result remained the same.
"You can't get out either?" William seemed to notice his situation and asked.
"Yeah. Doesn't look like you're too surprised." Daniel glanced at him and nodded.
"I expected something like this to happen. To leave this dungeon we'll need four or maybe even five keys."
"Four or five?" Daniel frowned and muttered to himself like he hadn't expected that.
Normally, leaving a dungeon without clearing it requires one key, the same key needed to challenge the tower floors. Almost every dungeon rank only needs one key, but there are exceptions. Some rare dungeons demand more than one key to leave.
