I just got to the pagoda of harmony and when my team finished, the two exalted wizards I was doing the dungeon with asked me if I got a skeleton key. After researching about them, I found that they open locked doors with loot. Is the loot inside the locked doors in the pagoda and hollow mountain worth it? Is it a good use of time to farm for the keys to get the loot? Is there any other good loot drops dropped by the bosses the the two dungeons? Thanks in advance.
