Generally all maps between Black Mountain Entrance and Goblin House have good exp, (with the exception of blins, they have two bodies which is awkward to train on), though the two listed above are the most popular and their fair share of bots and players, with Black Mountain Entrance having more bots and Goblin House having more players, making both a rather common ground for elite bossing. This map is GREAT for wind archers with chilling fusillade (3rd job skill) as you can literally just stand in the middle platform and hold down the skill to kill all the monsters (no need to move it around!). There's a small platform on the upper right, perfect for afk mules and a place to spawn mystic door. It has multiple platforms, 3 layers with the lower two connected and the top layer with a split in the centre, which is pretty annoying for most classes. Goblin House is another popular map, being the last map in the area with the highest levelled monsters. This is a great map for classes whose mobbing skills have a large nearby hit box as they don't need to move around often, such as bishops with big bang and xenons with fuzzy rob masquerade and blade dance. It's a small map with a flat platform and a hill in the centre, with many more platforms on the left for afk mules. The first map to the left, Black Mountain Entrance, is perhaps the most popular, with some people going there solely to train on the abundant moon bunny spawn.
