2564  * You may only fire items that "match" your missile launcher.
2565  *
2566  * You must use slings + pebbles/shots, bows + arrows, xbows + bolts.
2567  *
2568  * See "calc_bonuses()" for more calculations and such.

2570  * Note that "firing" a missile is MUCH better than "throwing" it.
2571  *
2572  * Note: "unseen" monsters are very hard to hit.
2573  *
2574  * Objects are more likely to break if they "attempt" to hit a monster.
2575  *
2576  * Rangers (with Bows) and Anyone (with "Extra Shots") get extra shots.
2577  *
2578  * The "extra shot" code works by decreasing the amount of energy
2579  * required to make each shot, spreading the shots out over time.
2580  *
2581  * Note that when firing missiles, the launcher multiplier is applied
2582  * after all the bonuses are added in, making multipliers very useful.
2583  *
2584  * Note that Bows of "Extra Might" get extra range and an extra bonus
2585  * for the damage multiplier.
2586  *
2587  * Note that Bows of "Extra Shots" give an extra shot.
