Section 3(d) - Combat-readiness
To decide whether combat proceeds:
if a hostile alive monster (called the baddie) is in the location, decide yes;
decide no.
Before reading a command:
if combat proceeds, now the command prompt is "Combat> ";
otherwise now the command prompt is "> ".
After waiting when combat proceeds: stop the action.
Check going (this is the need a saving roll to retreat rule):
if combat proceeds:
if a saving roll of 11 by the player to "disengage from the fight" is made, continue the action;
say "So you are unable to break away." instead.
Check casting (this is the can't cast non-combat spells in combat rule):
let the warlike nature be the nature of the spell understood;
if the warlike nature is defensive, let the warlike nature be offensive;
if combat proceeds and the warlike nature is not offensive:
say "The nature of that spell is [nature of the spell understood]: unlike offensive and defensive spells - which are structured for use in combat - [nature of the spell understood] spells need a little peace and calm to be cast." instead.
A person can be surprised or ready. A person is usually ready.
Instead of attacking a monster:
if the noun is hostile, say "You are already locked in combat." instead;
now the noun is hostile;
now the noun is surprised;
now the player is ready;
say "You make a surprise attack on [the noun]!" instead.
To mount an attack from (bad guy - a monster):
now the bad guy is hostile;
now the bad guy is ready;
now the player is surprised;
say "[The bad guy] attacks!"
Every turn when a hostile monster is in the location:
if the player is ready, make the player strike a blow against the scariest hostile monster in the location;[1]
repeat with the opponent running through hostile monsters in the location:
if the player is killed, stop;
if the opponent is ready:
if Zoorl is in the location, make the opponent strike a blow against Zoorl;
otherwise make the opponent strike a blow against the player;
now the player is ready;
now all hostile monsters are ready.
Note
[1]. Recall that "scary" was defined in 3(a) above: "scariest" automatically acquires the meaning of "that which is most scary".
