Spell Resistance: Yes
You scribe runes of dire power on a single missile or thrown weapon (usually an arrow, bolt, dart, javelin, or spear), changing the weapon into a sinister missile of cold, enhanced bone. When thrown or fired at a creature as a normal ranged attack, the weapon gains a +4 enhancement bonus on attack rolls and damage rolls. In addition, any living creature struck by an arrow of bone must succeed on a Fortitude save or be instantly slain. A creature that makes its save instead takes 3d6 points of damage +1 point per caster level (maximum +15). Regardless of whether the attack hits, the magic of the arrow of bone is discharged by the attack, and the missile is destroyed.
Material Component: A tiny sliver of bone and a vial of blood mixed with powdered precious gems worth 50 gp, used to paint the runes on the projectile.
