Warning

You cast this spell, and another worldly entity (such as a Clerics deity or a Warlock's patron) that would be willing to help you speaks to you. This entity warns you of danger that you might encounter in a half-mile radius or less, only if specified by the caster, such as traps in a dungeon or an archer hidden in a forest. Upon casting this spell, you get a word, or a short sentence that warns you of the danger. This assumes current positions and current status of people, traps, and gears in effect. This spell does not account for a change in position or the durability of a trap. This also does not reveal exact location of the warning. The words or phrases one can hear are the following:  

Trap-there is a trap nearby. 

Archer-if an enemy (someone who would immediately attack the caster and his allies), has a ranged weapon

Blades and blunts-if an enemy (someone who would immediately attack the caster and his allies), has a melee or martial weapon 

Danger-If there is an obvious natural or man-made structure or area that would cause harm such as a pool of lava or a spike-pit. 

Meta: this is deigned to help recon a general area or dungeon, not find one specific person or item.
