Virtues are angelic artillery, deployed on the battlefields of the War in Heaven to annihilate high value targets.
A Virtue is a crystal sphere with a red triangle at its center. The sphere is orbited by two gold rings and above it floats a smaller gold ring that serves as a halo. The Virtue has two wings of blue light, as well as two much smaller wings forming an arrow shape beneath its body.
When the Virtue's body is damaged the crystal bleeds.
