I have a quick question about the 360 version of divinity. I was just wondering how i can unlock the castle crasher achievement. I've been to stone, kali, keara and raze's flying fortress, plus the other flying fortress thats to the south of orobas fjords. I was told that you could bring them down and i would unlock the achievement, but i was told here that i dont really bring them down down, just kill every one there, which i have, but i havent unlocked the achievement. Is there something else i need to do? and btw can you melt the ice in Keara's frying fortress?
