47.9/60.8 I just noticed they added it to the wiki. http://www.shigoislands.info/doku.php?id=bloodcrystal_cave Deep down in the water. The cave entrance and cave itself are not for the feint of heart :)

@Exilog i had a blast with this cave by the way. Would love to see more challenging cavs such as this. there is a bug when you are inside the cave where you can pop out of the wall onto the mountainside of fukaso. Essentially there looks like a way up to the sky but you end up underwater and then pop out. I will get screen shots for you next time we go in.
