I got into the new Tower of Izyel today (the new instance dungeon)
Basically here is how it works.
You get a party (get a good one) and head into the tower at the Forest of Mist.
Basiclly u go from mob to mob fighting mobs in rooms. Each time u kill a mob u walk to the next room and kill a stronger mob. Bosses will pop up at different parts of the dungeon
Screenies
leesa, its not very awesome exp, except the quest, they'll lvl u form 40 to 45 in like one dungeon run. Most people just go because of the drops (blues drop all the goddam time). Its good money, you could make around 10g or 20g if you stayed there for like 3 days.
