A spell to enchant a (maximum one pound) wholly bone object (projectile). The enchantment lies dormant until the projectile is thrown at a target (invocation) or until Duration expires, whichever comes first. The success roll is made as the enchantment is invoked (thrown). If the spell fails or a person other than the caster throws the projectile, the enchantment is lost and the projectile performs as an unenchanted mundane object; it may strike the target even if the spell fails.
If the caster throws the projectile and the spell succeeds, a second test of Bone Sting ML is made to determine missile accuracy, instead of testing Throw skill. The projectile has the range modifiers of a taburi. The Aspect of the missile is determined randomly, if there is a choice. Upon striking the target, the projectile's Impact is increased by SI/2 (MS) or SI (CS).
Bone Sting cannot be combined with any other enchantment
ML61+: Caster can select strike aspect.
ML91+: Caster can lay the enchantment in "open mode". Such a projectile can be cast by a person other than the caster. In such cases, the enchantment is invoked by throwing and the accuracy is determined by testing the thrower's Throwing ML.
