|Rainbow Zone (Dungeon Crude)|
Study is an NPC.
Study is in the warp at the South of Travia Mountain. The game tells you that you are in Crude Dungeon 1F but actually you are inside the Rainbow Zone (Crude Dungeon). This is because Rainbow Zone is one map with Crude Dungeon. If you are level 90 or above you may access any of the portals by talking to Study.
