Detect weapons

From Ardrana

When the detect weapons spell is cast, the priest detects weapons in a path 10 feet wide and up to 90 feet long. The spell is blocked by solid stone at least 1 foot thick, solid metal at least 1 inch thick, or solid wood at least 1 yard thick.

The spell detects concealed, invisible, and improvised weapons that have been used to harm or are carried with intent to harm. Broken weapons are detected only if still usable. In some old ruins, this spell is rendered useless by the sheer number of abandoned weapons.

Note: This spell originally appeared in this form in Demihuman Deities for the AD&D game from TSR. Their use here is for the purposes of providing context for the campaign only.
