Eye of Fire

Readily flammable things in the symbol's area, such as paper, cloth and dry wood, burst into flame. A save is rolled for each item that could catch.

As a Symbol of Power, it is traced by hand, wand or staff, goes off when anyone but its caster sees or encounters it, reaches no more than 20 ft. in radius, and stays in place until a counter-symbol or a successful counter-spell (50% per try) removes it.
