  This spell functions as hex glyph, except you can store a hex or a major hex (but not a grand hex). You trace the glyph with incense, which must first be sprinkled with powdered diamond (as noted in the material line).
  Read magic allows its caster to identify a greater hex glyph with a DC 16 Spellcraft check.
