So, I've been trying to get the Cloak of the Deep for quite sometime now. Originally, when passing through the Undersea level, I took the
swamp path instead of the Forgotten Palace path.
I came back after finishing the level and killed/ absorbed the three enemies in the first level of the FP. When the blue memory stone appears, it isn't the Cloak of the Deep, instead it's a life stone. I've been following many faqs and I'm sure that it appears in the first area of the FP. I've killed the enemies in numerous ways (absorbed all enemies in the area, killed all enemies in the area, etc.) but still, it's a life stone. I have a small feeling this is due to the fact that I downloaded the add on pack that had a costume change for the Cloak of the Deep before actually getting it. My idea is supported by the fact that it does say I have the Cloak of the Deep in the main menu, but it doesn't show the other Cloaks I have yet to get.
Anyone have any ideas?
