I have released a new video covering the last guide for Caranthir Tower Reborn. The 2.2 update a while back introduced a new secret area to the tower and a puzzle which needed to be solved to gain entry. This video covers how to beat the puzzle and information on what you need and what you're going to find down there.
Be aware that there will be spoilers in this video so do not watch it if you're interested in figuring things out for yourself. The next video is going to be back to the Creation Kit for some PM related content.
