2774  * You may only fire items that "match" your missile launcher.
2775  *
2776  * You must use slings + pebbles/shots, bows + arrows, xbows + bolts.
2777  *
2778  * See "calc_bonuses()" for more calculations and such.
2779  *

2782  * Note: "unseen" monsters are very hard to hit.
2783  *
2784  * Objects are more likely to break if they "attempt" to hit a monster.

2787  *
2788  * The "extra shot" code works by decreasing the amount of energy
2789  * required to make each shot, spreading the shots out over time.
