Woodwisp arrow

Woodwisp arrow was a transmutation spell that magically altered an arrow, allowing it to pass through wood as if it were moving through air.

Effects
This spell only transformed the properties of the arrow but did not allow the caster to see through wooden objects or trees. The arrow had to be fired from a bow within seconds of the spell's casting or the magic would expire and there was no effect.

Casting
In addition to verbal and somatic components, this spell required an arrow of masterwork quality.
