Fourth + A Few Tips N Tricks:
On the map above take note of the red lines across paths, those are doors. Those door's ask you simple multiple choice security question's when you cannot be attacked. (Only in between them). That's why its call Stronghold of Security
Stronghold of Security is a great training area. Before training you should train your levels up slightly first. Pure account's often train on Minotaur's because they are great for the strength and good experience and due to there convenience. Then go the the 3rd level of the stronghold of security. The monster's that you want to train on are Giant Spiders. They will give you great statistics, they are level 50 and aggressive. Level 44 Zombies in the Pestilence Level are far better for experience and loot drops.
