Adjustments to AR

The following situations impose an adjustment to the Attack Roll (AR). A positive adjustment makes the roll more difficult, representing a penalty to the attacker.

In most situations, apply only the most significant relevant modifier. Multiple adjustments should only be combined when they arise from clearly distinct sources.

• Higher Ground: −5 AR
• Lower Ground: +5 AR
• Attacking While Running: +10 AR
• Target Moving Erratically: +10 AR
• Target Surprised: −10 AR
• Target Prone: −10 AR (melee) / +10 AR (ranged)
• Very Poor Visibility: +10 AR (darkness, heavy fog, smoke)
• Attacker Severely Wounded: +10 AR
• Improvised Weapon: +5 AR
• Unfamiliar Weapon: +5 AR
• Extreme Disadvantage: +20 AR
• Perfect Setup: −20 AR

Ranged Weapons

• Light Obstruction: +5 AR (thin foliage, light smoke)
• Heavy Obstruction: +10 AR (dense foliage, narrow gaps)
• Target Partially Covered: +5 AR (half cover, shield edge, low wall)
• Target Heavily Covered: +10 AR (three-quarters cover, arrow slit)
• Long Range: +5 AR (beyond optimal range)
• Extreme Range: +10 AR (maximum effective range)
• Shooting Into Melee: +5 AR
