Detect Traps

The sword senses any trap within 10 feet, if it is in the sword's line of sight. A trap, according to Hervé the Blade, is anything that would inflict a sudden or unexpected effect considered harmful or undesirable and that was intended as a trap by its creator. Thus, the sword would sense an area affected by the alarm spell, a glyph of warding or a mechanical pit trap, but it would not reveal a natural weakness in the floor, an unstable ceiling, or a hidden sinkhole. This property only reveals a trap is present. It doesn't reveal the location of each trap, but it does provide the general nature of the danger posed by the trap. This property can be used up to three times each day, resetting at dawn each day.
