Physical mirror

Physical mirror was a common spell used by clerics.

Effects
This spell functioned by folding the local space into an invisible disk that could be up to wide. The disk provided a powerful defensive shield, as any missile or spell it intercepts is sent back on along it's course. It is unidirectional, so the caster can send their own missiles or spells through it. During casting, the caster had to determine both the location and orientation of the disk. Once cast, the disk could not be moved. If two physical mirror disks come into contact with each other, a violent reaction occurred and both instantaneously vanished. It send a destructive wave through space and time and any creature within, including the caster, were at risk.

Components
In addition to verbal and somatic components, the spell required a material component, a small mirror made from finished platinum. It had to have a value of at least 500 gp.
