Translations:Continent Bosses/3/en

Once you reach another teleport with skull signs, then you arrived at its spawning room.

Turtleneck room entrance

Head inside and go north. You will then find the coal basin to sacrifice the required items so it can spawn, which, in this case, are the green crystal fragments. These can be obtained through mainland's quests. Once you have this item, just throw it/them at the basin. For this boss, you need a total of 1000 green crystal fragments in order to spawn turtleneck.
