Range 10' per level of the caster
Area of Effect 30' square
This spell is often employed by court wizards and mages that are hired by the royal court, to provide an extra layer of security for rulers. Some High Temples also employ hedge wizards who use this spell, from the shadows, too.
Upon casting, the all weapons within a thirty foot square area will immediately glow a bright red that shows through clothing. In addition, the caster will instantly know what weapons all within the area have in their possession, concealed or not. He will not know if a weapon is magical (i.e. it does not identify it), nor how much ammunition is possessed if a weapon requires it. If a weapon requires assembly and is not assembled, then if any of its parts would be considered weapons (for example, an iron pipe could be wielded as a club) then these will be revealed to the caster, too.
Proof against scrying may defeat this spell at the DM's discretion.
