Stone Arrow

Stone arrows are considered flight arrows for game purposes, except that the stone arrowheads cause less damage and have a tendency to shatter if they impact armor or similarly hard surfaces. If a stone arrow hits any object made of metal, stone, or a harder substance, it has a 20% chance of surviving the hit without damage to the arrow. If a die roll does not indicate success, the arrow is still allowed a saving throw vs. crushing blow with a +4 bonus using the figures for Rock Crystal. Failure indicates that the arrow shatters.
Stone arrowheads are almond shaped or rhomboid and are usually made from stone splinters of flint or obsidian.
