Does the no save for wooden item included attended wooden objects as a specail case so would it catch fire within 5 feet of the target square catch a mass of troops with wooden shields on fire and do 2d6 points of fire damage to all of the shields of everyone in the area? If I shoot this out of a +1 catipult does the fire damage needing a save to aviod get the +1 damage as well and same with flaming.
