Special Arrows
　Practitioners of Kyujutsu (pp. 179-180) – and many other archers – will be familiar with these special arrowheads as well as with regular and bodkin points (p. B277):

Barbed: Yanking out a barbed arrow inflicts half the injury it delivered going in. No effect on cost or weight (most war arrows are barbed by default). Blunt: Converts damage to crushing. Used for training or for hunting fowl. Half cost, normal weight.

Bowel Raker: Converts damage to cutting. Gives -1 to Acc and subtracts 5 from both Range multipliers; e.g., \15/\20 becomes \10/\15. Yanking it out inflicts half the injury it delivered going in. No effect on cost or weight.

Frog Crotch: Has a C-, U-, or Y-shaped head sharpened on the inside of the curve. Used against limbs, and to cut ropes or (in heroic stories) bowstrings. Converts damage to cutting. No effect on other statistics.

Humming Bulb: Has a hollow, fluted tip that whistles in flight. Used to signal or to flush game. Some of these heads can carry a tiny payload – often an oil-soaked rag. Gives -1 to Acc and subtracts 5 from both range multipliers.
Damage becomes crushing with an armor divisor of (0.5). No effect on cost or weight.

Willow Leaf: Converts damage to cutting. No effect on other statistics.
