Hints needed!

[QwxJ]

Hello there, always been a big fan of the map and recently managed to get some friends to try it. No suprise they loved it, and we've been playing it quite a bit trying out new heroes and all. But we have reached a wall when it comes to progressing on Legendary Power. I know it's optional and not required, but every game we try our best to figure things out and always end up at the same spot - with absolutely no clue what to do to get the titanforged head. I'm pretty sure the skeleton in the treasury and the king's blood are somehow involved, but have no clue how to free the skeleton or where to even find the king's blood. So its come to the point that I'm asking for help here, not a direct answer, but at least some hints as to what to do. Thanks in advance!
