Stylet Bonespear (3.5e Equipment)

The Stylet Bonespear is a thin lance made of bone with a slit end which is shaped like a syringe, the inside hollow with channels running up the edges and out to "exhaust ports" along the sides. When striking the opponent, it may dig deep and strike a major blood vessel, allowing the body's own blood pressure to pump its lifeblood up through the spear and outside the body, dealing grievous damage.

A stylet bonespear has reach. You can strike opponents 10 feet away with it, but you can’t use it against an adjacent foe. If you use a ready action to set a stylet bonespear against a charge, you deal double damage on a successful hit against a charging character. A stylet bonespear is considered any spear (shortspear, spear, longspear, and the like) for the purpose of feats and class features which apply to them.

As long as you have the appropriate proficiency, this weapon gains several benefits which are based on your BAB. As you become a more skilled warrior, so too do you learn to use this weapon to greater effect. All benefits function only on creatures with blood, even if they are immune to critical hits (so a critical on a vampire would deal +2d6 damage, but the vampire remains immune to the Con damage and x4 damage from a critical.)

+1 BAB: On a critical hit, you deal an additional 2d6 damage.

+5 BAB: On a critical hit you may forgo the additional damage bonus and instead deal 1 Con damage.

+10 BAB: You may ignore up to 25% fortification (immunity is treated as 100% fortification). This only permits you to make a critical hit, and does not allow you to sneak attack creatures which can not be sneak attacked.

+15 BAB: You no longer need to forgo the bonus damage on a critical hit, and your critical hits now deal 2 Con damage.

+20 BAB: You may ignore up to 50% fortification, with the same limitations as before.

+25 BAB: Your critical hits now deal 1d4+1 Con damage on a critical hit.

+30 BAB: You may ignore up to 75% fortification, with the same limitations as before.

Osteons treat this weapon as a martial weapon. Such weapons are usually crafted through the bone shape spell, although the end result is mundane.
