Sentient Weapon Walkthrough

You need to get the grip from the actual hilt of the broken sword that the elf statue is holding. To do this, you need to get up top. Run around the back of the ruin and there's a large rock situated near a corner of the ruin. Hop on that, then onto a ledge, then up onto the top of the ruin. Once up there you can walk onto the arms of the statue, and grab a piece of the hilt.
