Untrained Fighters
Untrained fighters are a danger to themselves . . . and often to their allies, too! These optional rules simultaneously make such combatants less predictable and limit their choices. They’re realistic but add extra complexity.

Fear
Combat is frightening to the unprepared. At the start of hostilities – when “slow” time starts and combatants start acting turn-by-turn (see Time During Adventures, p. B497) – those with neither combat skills nor Combat Reflexes must make a Fright Check (p. B360). Apply the usual +5 for the “heat of battle” and any bonus for a successful Leadership roll by the group’s leader (see p. B204). The GM may rule that those who fail simply drop their weapons and flee instead of rolling on the Fright Check Table.

“Coin Toss” Option
If someone with neither combat skills nor Combat Reflexes passes his Fright Check, he may elect to back off (a series of Move maneuvers) instead of turning his back to the foe and fleeing. If he chooses to fight, though, roll 1d at the start of his turn:
1-3 – He attacks the nearest foe that poses a danger – to him, a Dependent, an Ally, an adventuring companion, or a bystander, in that order. To offset his lack of skill, he makes an All-Out Attack (Determined) without realizing it!
4-6 – He decides to protect himself. He uses All-Out Defense (Increased Dodge) to move away from the nearest foe. If he has a ready weapon or shield, he may select Increased Parry or Increased Block instead.
Roll again each turn!

Limited Maneuver Selection
Untrained fighters have a narrower tactical palette than skilled martial artists. Only combatants with at least DX level in a melee combat skill (1 point if Easy, 2 points if Average, or 4 points if Hard) can choose a Committed Attack, Defensive Attack, or Feint maneuver, or exercise combat options such as Deceptive Attack, Defensive Grip, and Rapid Strike. Exception: Anyone can attempt a Telegraphic Attack. Unskilled fighters are more likely to choose this option!

Combat Art or Sport Fighters
Those who know only Combat Art or Sport skills might count as “untrained.” Actual combat skills default to their Art/Sport analogs at -3, so a fighter who has only an Art/Sport skill needs DX+3 level (8 points if Easy, 12 points if Average, or 16 points if Hard) to choose the maneuvers and options above.
