I have made it to the castle and I need to find five golden leafs for Richard. I have already found one by killing the guy outside with the bombs. Killing some soldiers in the first room. Using bombs to blow statues on the wall, which spawned two more soldiers. Killing them dropped a leaf and then finally from a large soldier with a spiked ball in chain. Where is the final one that I am missing?
Go back outside and you will see a bird sitting on top of the tree to the left side of the castle. Killing this bird will give you the last leaf
