Mirror

Regular 
Creates a reflective surface. It can be cast on an object or can be free- standing (in which case it is two-sided). The mirror surface is not necessarily flat; the caster could create fun-house mirrors, for example. 
In a scientific-paradigm universe, casters with knowledge of physics can use this spell to create parabolic reflectors. A simple curve can be sufficient to cook meat; a large and precise one could be used to melt lead, given sufficient sunlight at appropriate angles. Against living targets, the GM can assume that such a mirror would do 1 point of burning damage per yard radius of mirror every 10 seconds. To ignite things, use the Ignite Fire guide-lines, substituting the Mirror size for the listed energy cost. An 8- yard-radius Mirror ignites heavy wood in about 10 seconds. Other, similar uses are subject to GM approval.
