41 ** Klingon Attack Routine
43 ** This routine performs the Klingon attack provided that
44 ** (1) Something happened this move (i.e., not free), and
45 ** (2) You are not cloaked. Note that if you issue the
46 ** cloak command, you are not considered cloaked until you
49 ** Klingons are permitted to move both before and after the
50 ** attack. They will tend to move toward you before the
51 ** attack and away from you after the attack.
53 ** Under certain conditions you can get a critical hit. This
54 ** sort of hit damages devices. The probability that a given
55 ** device is damaged depends on the device. Well protected
56 ** devices (such as the computer, which is in the core of the
57 ** ship and has considerable redundancy) almost never get
58 ** damaged, whereas devices which are exposed (such as the
59 ** warp engines) or which are particularly delicate (such as
60 ** the transporter) have a much higher probability of being
63 ** The actual amount of damage (i.e., how long it takes to fix
64 ** it) depends on the amount of the hit and the "damfac[]"
65 ** entry for the particular device.
67 ** Casualties can also occur.
