2649  * You may only fire items that "match" your missile launcher.
2650  *
2651  * You must use slings + pebbles/shots, bows + arrows, xbows + bolts.
2652  *
2653  * See "calc_bonuses()" for more calculations and such.
2654  *
2655  * Note that "firing" a missile is MUCH better than "throwing" it.
2656  *
2657  * Note: "unseen" monsters are very hard to hit.
2658  *
2659  * Objects are more likely to break if they "attempt" to hit a monster.
2660  *
2661  * Rangers (with Bows) and Anyone (with "Extra Shots") get extra shots.
2662  *
2663  * The "extra shot" code works by decreasing the amount of energy
2664  * required to make each shot, spreading the shots out over time.
2665  *
2666  * Note that when firing missiles, the launcher multiplier is applied
2667  * after all the bonuses are added in, making multipliers very useful.

2670  * for the damage multiplier.
2671  *
