Crystal Fortress

 is a piece of equipment in Torment: Tides of Numenera.

Description
This dark purple crystal was placed into a synthsteel device - or perhaps the device was built around it. The crystal shimmers with barely restrained power, occasionally shifting as if testing the strength of its constraints. When you deactivate the container, the crystal loses its integrity, shattering into two parts, which in turn will shatter into two, and so on and so forth, smaller and smaller. With each breaking, the crystal unleashes a protective energy that wraps around the user, turning away incoming strikes, though it is not capable of turning away immediate attacks.
