The original post [GUIDE] Temple of Ochao
This guide will contain the description of the run, the strategy to be used in this run, my personal considerations (which you can skip) and the maps required.
This run is different from other runs because it can be accessed by two separated groups which will be adversaries for all the time they are inside the dungeon. The min lv required to enter is 100 and only groups can join, not solo players. Monsters are aggressive, they look like lemures but they have very good damage. There are close combat monsters and long range monsters. I did not notice any way to block the damage from long range monsters but the rest of them are easy. Players can choose to farm the monsters or complete the run; or maybe both.
Ochao run can be accessed once players who are on the marked spot in the Enchanted Forest kill the En-Tai Guardian. Once it is killed a NPC called Blue Portal appears which will teleport the group inside the run. Please note that players can get inside the dungeon in a time frame of 10 mins, after which the NPC will disappear. Reconnection is possible from the Chief of the Forest NPC located at the top of the map Enchanted Forest. Players can only die once, if they get killed twice they are kicked from the run.
In order to complete the run players must first kill 4 Ochao Prince marked in the run map with X. Once they all are killed they will be replaced by 4 Strong Ochao Prince which have to be killed as well. They spawn in the same spots as Ochao Prince do. After all 4 Strong Ochao Prince are killed the main boss will be spawned in one of places marked on the map. The run ends after its death and everybody is teleported back in the Enchanted Forest.
Monsters in the run are Devil but the main boss, Jotun Thrym, it is not.
The available time for the run is 30 minutes.
The cooldown between runs is one hour and 30 minutes.
The En-Tai Guardian spawns every two hours in the spot marked on the Forest map.
The group(s) must first kill the Ochao Princes. I marked on the map the locations and the path to follow, with different colors. We split the group in two and one goes middle while the other follows the blue path. With purple i marked the junction path to be followed in case the main boss is in the other team's area. In the places marked STOP is the point where players should pull the boss with capes or shoot arrows at to kill it faster. In Metin2 the maze is an access limitation for players only, not for monsters.
None of the bosses deal any skill damage or normal damage. The drop is impressive, both from normal monsters and bosses.
Monsters respawn when the bosses are replaced by their stronger version. It will be really unpleasant to be surprised in a respawn by a strong wave of monsters.
Jotun Thrym must be separated from its guardians if players won't like to kill them as well to keep the boss' damage low.
Here comes the part you might want to skip:
The run is designed to keep high lv players busy with the high lv accessories, armours and alchemy. While the concept of creating a dungeon where two groups can be inside in the same time is interesting, the idea to put them in a state of war for the duration of the run it is not as useful as one might think. I strongly believe it was for the better to promote cooperation than competition inside the run, thus designing the run in such a way only one team could not achieve anything without the presence of second team that could complete separated tasks. I think high lv players can find many reasons to kill and hate each other but none to cooperate without being asked to do so if they want to have access to new items.
