The Focusser Crown
Focus crystals enhance a wizard's ability to control magic and amplify its effects. The Focusser crown was made for the head of the Sechsäugigerwyrm, Otto Von Gisen, to enhance his personal power. It magnifies his power six-fold.
It was crafted by Anna-Lise Baldour from five amost perfectly identical focusser crystals which were made at the research station of the Geman magical division of the SS. The five crystals are pure quartz, she added a few rubies and sapphires as decoration: they are magically inert.
