So you kill the specter and the regular skeletons after you pick up the note. The exit is still barred by a gate, and you are automaticaly assaulted by over a dozen ghostly skeletons? Ghost Touch doesn't hit them, conventional weapons will not hit them, and you start to run for the entrance because you cannot finish out without getting interrupted. What happens now? Well I am sure when the game came first came out the party would survive and exit. Now however, the party gets harried with a red dungeon alert and gets wiped.
Come on Turbine, if you finish a quest, the end (while it may have *OPTIONALS* left) should not mean a party wipe because the level 5's that went into it don't have special weapons to fight an optional MOB.
Fix it.
