3D6 Stats Combat — Table How-To

Rules: 3D6 Stats · Status: Rules-as-written reference · House-rule changes: None

This is a table procedure, not a replacement rulebook. It puts the ordinary 3D6 Stats combat cycle in one place so we can resolve a fight without hunting through six tabs while somebody’s sandwich goes cold.

Primary references: Basic Set pp. B363–B426, combat modifier tables pp. B547–B550, and the free 3D6 Stats Lite combat summary.

> First correction: 3D6 Stats does not normally roll initiative. Turn order comes from Basic Speed and stays fixed for the fight.


The whole cycle

For each combatant, in turn order:

  1. Resolve start-of-turn conditions.
  2. Choose one maneuver.
  3. Declare movement, target, attack mode, and options.
  4. Calculate effective skill.
  5. Roll the attack.
  6. If the attack succeeds, resolve the target’s active defense.
  7. If defense fails, roll basic damage.
  8. Apply range effects, DR, penetration, wounding modifiers, and hit-location effects.
  9. Record injury and its immediate consequences.
  10. Finish movement or minor bookkeeping allowed by the maneuver.

After everyone has acted, one second has passed. Start again at the top of the same order.


1. Start combat: order, awareness, and surprise

Establish the scene first

Before the first turn, the GM should establish:

  • Where everyone is.
  • Who can see or otherwise detect whom.
  • Distance and facing.
  • Posture: standing, crouching, kneeling, prone, and so on.
  • Cover and concealment.
  • What each person already has ready.
  • Whether either side is surprised.

Turn order

Order all active combatants from highest Basic Speed to lowest.

Ties:

  1. Higher Basic Speed before rounding.
  2. For PCs, higher DX.
  3. If still tied, roll once to establish their order.
  4. Keep that order for the rest of the fight.

NPCs tied with one another can simply act in whatever order the GM finds easiest.

Surprise

Resolve surprise before ordinary turns. A surprised or mentally stunned combatant generally Does Nothing and attempts the appropriate recovery roll on their turn. Once recovered, they rejoin their normal place in the established order.

What a “turn” means

A turn runs from the moment a combatant chooses a maneuver until that combatant chooses again on their next turn. Maneuver effects do not all vanish when the last person in the order acts.

That matters. All-Out Attack leaves you defenseless until your next turn. All-Out Defense protects you until your next turn. 3D6 Stats turns overlap; they are not little sealed boxes.


2. Start-of-turn checks

Before choosing a maneuver, check:

ConditionWhat happens
Physical stunTake Do Nothing; roll HT to recover at the end of the turn.
Mental stunTake Do Nothing; roll IQ to recover at the end of the turn.
0 HP or lessMake the required HT roll to remain conscious if taking action or defending. Penalty worsens at deeper negative HP.
Death threshold crossedMake the required HT death check immediately.
Less than 1/3 HPMove and Dodge are halved.
Less than 1/3 FPMove, Dodge, and current ST are halved for relevant actions; derived ST-based quantities are not recalculated.
Shock from the previous injuryApply its DX/IQ penalty this turn, maximum -4. It does not reduce active defenses.
Ongoing effectResolve fire, poison, suffocation, bleeding, affliction, spell, or other timed effect as its rule requires.

Then choose a maneuver.


3. Choose one maneuver

ManeuverWhat it doesMovement and defense
Do NothingPause, recover from stun, or take no meaningful action.No useful movement; normal defenses unless stunned, in which case defenses are at -4.
MoveMove up to full Move.Normal defenses.
Change PostureStand, kneel, sit, crawl, or lie down.Normal defenses; posture modifiers apply.
AimTrack one target with one ranged weapon.Usually a step; normal defenses, but defending may spoil the Aim.
EvaluateStudy one melee opponent.Step; +1 to the next melee attack against that foe per turn, maximum +3.
AttackMake one ordinary melee or ranged attack.Step; normal defenses.
FeintContest melee skill to reduce the foe’s next defense against you.Step; normal defenses.
All-Out AttackTrade defense for accuracy, force, or extra attacks.Up to half Move forward; no active defense until the next turn.
All-Out DefenseIncrease one defense or try two different defenses against one attack.Movement depends on the option; no attack.
Move and AttackMove up to full Move and attack badly.Ranged attack uses -2 or Bulk, whichever is worse; melee is -4 and capped at effective skill 9. No parry until the next turn.
ReadyDraw, reload, change grip, ready an unbalanced weapon, operate equipment, or pick something up.Step; normal defenses.
ConcentratePerform a mental task, use many abilities, or cast as required.Step; normal defenses, but interruption may require a Will roll to maintain concentration.
WaitName a visible trigger and the response you will take when it occurs.You act when the trigger happens, potentially interrupting the normal order.

Free actions include short speech, dropping a ready object, and certain posture adjustments such as crouching. “Free” does not mean “deliver a TED Talk while firing a plasma rifle.”


4. If attacking, make the declaration before rolling

State all of this before touching the dice:

  1. Target.
  2. Weapon or unarmed attack.
  3. Attack mode: swing, thrust, punch, kick, burst, and so on.
  4. Hit location, if not attacking the torso.
  5. Maneuver option: Determined, Strong, Double, etc.
  6. Special option: Deceptive Attack, Rapid Strike, off-hand attack, and so on.
  7. Movement taken before or after the attack.
  8. Ammunition and number of shots, for ranged weapons.

You cannot wait to see the roll and then announce that, actually, the shot was aimed at the eye. Nice try, Spielberg.


5. Calculate effective attack skill

Start with the relevant weapon or unarmed combat skill. Apply every modifier that fits. Modifiers are cumulative unless a rule says otherwise.

Common modifiers to any attack

SituationModifier
Shock from injury received since the previous turn-1 per HP lost, maximum -4
Bad footingUsually -2 or worse
Minor distractionUsually -2
Major distractionUsually -3 or worse
Grappled-4 to DX and most DX-based actions
ST below a weapon’s minimum ST-1 per missing ST
Off-hand attack-4 unless removed by Ambidexterity or the appropriate training
Cannot see anything-10, or -6 if accustomed to blindness
Cannot see the known targetUsually -6; -4 if location is known within one yard
Partial darkness, fog, smoke, glare, or concealment-1 to -9

Poor visibility penalties do not stack forever. Use the worst applicable visibility condition, up to the system’s normal cap.

Posture

Attacker’s postureMelee attackActive defenseRanged attacks against themMovement
Standing000Normal
Crouching-20-22/3 Move
Kneeling-2-2-21/3 Move
Crawling-4-3-21/3 Move
Sitting-2-2-2None
Lying down-4-3-21 yard/second

The target penalty assumes the attacker is not directly above or extremely close. Cover and exposed body parts can change matters.


6. Melee attack modifiers

The target must be within the attack’s Reach. Reach C means close combat; Reach 1 means roughly one yard; longer weapons may reach farther but can become awkward up close.

Choice or circumstanceModifier/effect
AttackOrdinary skill roll.
All-Out Attack (Determined)+4 to hit; no defense afterward.
All-Out Attack (Strong)Normal roll; +2 damage or +1 per die, whichever is better, for ST-based melee damage; no defense.
All-Out Attack (Double)Two eligible attacks; no defense. Off-hand penalties still apply.
Evaluate+1 per preceding Evaluate turn, maximum +3.
FeintQuick Contest; victory penalizes that foe’s defense against your next eligible melee attack.
Deceptive AttackTake -2 to hit for each -1 applied to the target’s active defense. Effective skill must remain high enough to attack.
Rapid StrikeTwo attacks at -6 each. Trained by a Master or Weapon Master halves this to -3 each.
Dual-Weapon AttackNormally -4 to each attack, plus any off-hand penalty.
Move and Attack-4, and effective melee skill cannot exceed 9.
Wild Swing-5 and effective skill cannot exceed 9.
Striking into close combat-2; a miss can endanger the wrong person.
Large shield carried while attacking-2.

Trained by a Master does not add damage. It grants access to cinematic abilities and improves penalties such as Rapid Strike and repeated parries. Do not quietly staple Weapon Master’s damage bonus onto it.

Common hit-location penalties

LocationTo hitImportant result if damage penetrates
Torso0Normal damage-type effects.
Arm or leg-2Injury over HP/2 in one wound can cripple; excess injury is capped.
Vitals-3Impaling and piercing injury usually becomes ×3; tight-beam burning can receive a special multiplier.
Groin-3Torso injury, with extra knockdown/shock consequences in applicable anatomy.
Hand or foot-4Injury over HP/3 can cripple; excess injury is capped.
Face-5Easier than skull; severe knockdown and critical-head effects can apply.
Neck-5Cutting becomes ×2; crushing/corrosion can become ×1.5.
Skull-7Extra DR 2; penetrating injury becomes ×4; severe knockdown penalty.
Eye-9Only suitable attack types; no skull DR for the eye itself, but penetrating injury uses skull effects and can blind.

Not every damage type can exploit every location. If the attack could not physically produce the listed special effect, use the ordinary result.


7. Ranged attack modifiers

The target must be within Max range. Range affects the attack roll. Crossing 1/2D range also reduces basic damage.

Build the ranged attack number

Start with weapon skill, then apply:

  1. Target Size Modifier.
  2. Speed/range modifier.
  3. Aim and equipment bonuses.
  4. Maneuver modifier.
  5. Visibility, posture, cover, movement, and situational modifiers.
  6. Hit-location penalty.
  7. Rapid-fire bonus, if any.

Common range penalties

Use the Size and Speed/Range Table when precision matters. These are the common human-scale entries:

Range or speed+rangeModifier
2 yards0
3 yards-1
5 yards-2
7 yards-3
10 yards-4
15 yards-5
20 yards-6
30 yards-7
50 yards-8
70 yards-9
100 yards-10

For a fast target, add speed in yards/second to range before consulting the table. Human movement on foot is commonly ignored unless unusually fast or tactically important.

Aim and ranged options

Choice or circumstanceModifier/effect
One Aim maneuverAdd the weapon’s Acc.
Braced after AimUsually +1.
Two seconds of AimAcc plus another +1.
Three or more seconds of AimAcc plus another +2.
ScopeUsually +1 per second of Aim, up to the scope’s rating.
Laser sightUsually +1 when its dot can be used.
All-Out Attack (Determined)+1 to hit; no defense afterward.
Move and Attack-2 or the weapon’s Bulk, whichever is worse; Aim bonuses are lost.
Pop-up attack-2; no Aim bonus.
Unfamiliar weapon or sighting systemUsually -2.
Close combat with a firearmApply the weapon’s Bulk.
Target partly exposedUsually -2, or attack an exposed hit location.
Shooting through light coverUsually -2; solid cover may stop the shot and adds its DR.
Intervening person-4 per intervening figure.

Target size

Add the target’s Size Modifier:

  • Ordinary adult human: SM 0.
  • Larger target: bonus.
  • Smaller target: penalty.

Do not apply both Size Modifier and a second made-up “small target” penalty for the same thing.

Rapid fire and recoil

Shots firedBonus to hit
2–40
5–8+1
9–12+2
13–16+3
17–24+4
25–49+5
50–99+6

On a successful rapid-fire attack, the margin of success and the weapon’s Recoil (Rcl) determine additional hits. Each hit normally gets its own damage roll and DR application.

Rapid fire improves the chance of landing one or more hits. It does not add the rate-of-fire bonus to damage.


8. Roll the attack

Roll 3d against effective skill.

  • Roll equal to or below effective skill: potential hit.
  • Roll above effective skill: miss.
  • 3 or 4: always a critical hit.
  • 5 is critical at effective skill 15+.
  • 6 is critical at effective skill 16+.
  • 17 or 18: always a miss; often a critical miss depending on effective skill.

A critical hit normally denies an active defense and uses the appropriate critical-hit rule. Otherwise, the defender may attempt one legal active defense.


9. Defender chooses an active defense

The defender must be aware of the attack and physically able to react.

DefenseBase calculationCommon limits
DodgeBasic Speed + 3, drop fractions, minus encumbranceCan be used repeatedly against separate attacks; usually the defense against firearms.
Parry3 + half the relevant weapon or unarmed skill, drop fractionsWeapon must be ready. Repeated parries accumulate penalties. Most ranged projectiles cannot be parried.
Block3 + half Shield skill, drop fractionsRequires a ready shield; normally one block per turn. Firearms and beams are generally too fast to block.

Add shield or cloak DB when the attack comes from a protected direction and the attack permits it.

Common defense modifiers

SituationModifier/effect
Combat Reflexes+1 to active defenses.
All-Out Defense (Increased Defense)+2 to one chosen defense.
All-Out Defense (Double Defense)Try a second, different defense if the first fails.
Retreat+3 to Dodge or a fencing, Boxing, Judo, or Karate Parry; +1 to most other Parries or Blocks.
Acrobatic Dodge+2 on a successful Acrobatics roll; -2 if that roll fails.
Dodge and Drop against ranged attack+3 to Dodge, but you end prone.
Stunned-4 to all active defenses.
Cannot see the attacker-4; Block or Parry may require a Hearing roll.
Attack from behindUsually no defense.
Side or runaround attackUsually -2 unless protected by Peripheral Vision or another rule.
Bad footingUsually -1 or worse.
EncumbranceReduces Dodge and certain unarmed/fencing Parries.
Successful FeintDefense penalty equals the attacker’s margin of victory.
Deceptive Attack-1 defense for every -2 the attacker accepted.
FlailStrong penalty to Parry and a smaller penalty to Block.
Off-hand ParryUsually -2.
Repeated ParryUsually -4 per additional Parry; halved for fencing weapons, Trained by a Master, or Weapon Master.

Roll 3d. Equal to or below effective defense means the attack is avoided. Failure means the attack hits.


10. Determine the weapon’s basic damage

Firearms, beams, and self-powered weapons

Use the damage printed in the weapon’s stat line, then apply ammunition, firing-mode, quality, or equipment rules that explicitly change it.

The shooter’s ST normally does not increase firearm damage.

Muscle-powered melee and thrown weapons

  1. Find the attacker’s thrust (thr) or swing (sw) damage from ST.
  2. Use the mode listed for the attack.
  3. Apply the weapon’s listed add or subtraction.
  4. Apply any legitimate damage bonuses.

Example structure: sw+1 cut means swing damage from ST, plus one, causing cutting damage.

What can alter the damage number?

SourceEffect
Attacker’s STSets thrust/swing damage for muscle-powered attacks.
Weapon’s attack modeSwing and thrust often have different damage and damage types.
Weapon’s listed modifierAdds or subtracts exactly what the stat line says.
All-Out Attack (Strong)+2 or +1 per die, whichever is better, for ST-based melee damage.
Weapon MasterCan add damage with covered weapons when skill is high enough.
Karate, Boxing, or BrawlingCan add unarmed damage at the skill levels specified by that skill.
Fine or Very Fine cutting/impaling weaponCan add its listed quality bonus. Quality does not universally increase every damage type.
Mighty BlowsIf using the standard optional Extra Effort in Combat rule: spend 1 FP for +2 or +1 per die, whichever is better.
Half-Damage rangeAt or beyond 1/2D, halve basic damage and round down before DR.
Ammunition or firing modeArmor-piercing, hollow-point, shotgun, explosive, incendiary, and similar rules may alter damage, armor divisor, damage type, or wounding.
Critical hitMay maximize damage or produce another result from the applicable critical table.
Multiple hitsEach hit causes a separate damage roll unless its rule says otherwise.

What does not normally add damage?

  • Trained by a Master by itself.
  • Aim or Acc.
  • Range penalties to hit.
  • Rapid-fire bonus to hit.
  • Evaluate.
  • Deceptive Attack.
  • Feint.
  • Margin of success on an ordinary attack.
  • A high weapon skill unless a specific advantage or skill rule converts it into damage.
  • Being below a weapon’s minimum ST. That penalizes use and may affect readiness; it does not invent a new damage subtraction unless the weapon rule says so.

11. Convert basic damage into injury

Do this in order. Do not jumble the steps; that is how a 9mm round somehow becomes a naval gun.

Step A: apply pre-DR changes

  • Apply the attack’s damage additions or subtractions.
  • At this stage, a negative modifier cannot reduce crushing damage below 0 or most other damaging attacks below 1.
  • Then apply 1/2D range if relevant: halve basic damage and round down. This halving can reduce an already small result further.

Step B: determine effective DR

Use DR protecting the actual hit location.

  • Add compatible layers when permitted.
  • Include cover DR if the attack passed through cover.
  • Apply the attack’s armor divisor to DR, not to damage.
  • A divisor below 1 increases effective DR.

Step C: subtract DR

Basic damage - effective DR = penetrating damage

If penetrating damage is 0 or less, the attack did not penetrate. Check whether flexible armor, blunt trauma, knockback, or another special rule still matters.

Step D: apply the wounding modifier

Damage typeOrdinary wounding modifier
Small piercing (pi-)×0.5
Piercing (pi)×1
Large piercing (pi+)×1.5
Huge piercing (pi++)×2
Cutting (cut)×1.5
Impaling (imp)×2
Crushing (cr)×1
Burning (burn)×1

Some hit locations replace these multipliers. Round fractions down. Any attack that penetrates normally causes at least 1 HP of injury.

Step E: apply hit-location effects

Check:

  • Changed wounding multiplier.
  • Extra DR, especially the skull.
  • Crippling thresholds for limbs and extremities.
  • Maximum injury caps.
  • Eye injury and blindness.
  • Knockdown penalties.
  • Vitals or neck effects.

The final number after these steps is injury. Subtract it from HP.


12. Resolve immediate injury effects

Work through this checklist after every damaging hit:

Shock

On the victim’s next turn, DX and IQ are reduced by injury from that hit, to a maximum of -4. Shock does not reduce active defenses.

High Pain Threshold removes ordinary shock penalties and improves several resistance rolls; it does not reduce injury.

Major wound

A single injury greater than half the victim’s HP is a major wound. Make the required HT roll for knockdown and stunning. Certain hit locations or damage types apply additional penalties.

On failure, the victim falls prone and is stunned. On the victim’s turns, use Do Nothing and roll to recover.

Crippling

Check limb, hand, foot, eye, and other location thresholds. Excess injury to a limb or extremity can be discarded after reaching its cap; it does not spill into the torso unless a specific rule says otherwise.

Knockback

Crushing attacks and certain other effects can cause knockback even when injury is modest. Compare the applicable damage to the target’s ST/HP threshold, move the target, and check for falling or collisions as required.

HP thresholds

Current HPEffect
Less than 1/3 HPHalve Move and Dodge.
0 HP or lessHT checks to remain conscious when acting or defending.
Each negative multiple of HPImmediate HT death check.
-5×HPAutomatic death.
-10×HPTotal bodily destruction when the damage source makes that plausible.

Other consequences

Depending on the attack, also check:

  • Bleeding.
  • Fire or continuing damage.
  • Poison or follow-up damage.
  • Explosion and fragmentation.
  • Electrical stunning or surge effects.
  • Knockdown from a head, face, vitals, or groin hit.
  • Weapon breakage, dropping an item, or loss of readiness.
  • Fright Checks or morale when the fiction warrants them.

13. Finish the acting character’s turn

After resolving the attack:

  1. Finish any movement still permitted by the maneuver.
  2. Mark ammunition spent.
  3. Mark an unready weapon, empty chamber, changed grip, lost Aim, or expended FP.
  4. Record ongoing maneuver effects.
  5. Record Wait triggers, concentration, suppression, or other continuing actions.
  6. Move to the next combatant in the fixed order.

Remember:

  • An active defense happens during the attacker’s turn, but counts against the defender’s limits until the defender’s next turn.
  • Maneuver restrictions last until the combatant chooses a new maneuver.
  • A Wait can interrupt the ordinary order.
  • Shock applies on the injured character’s next turn, not at some universal “end of round.”

14. End of the one-second cycle

After the last combatant acts:

  • One second has elapsed.
  • Advance durations that count whole seconds.
  • Resolve any effect specifically timed for the end or start of that second.
  • Do not erase every bonus, penalty, defense use, or maneuver automatically.
  • Return to the first surviving, conscious, active combatant in the established order.

The GM can leave combat time when second-by-second resolution no longer matters. Chasing a fleeing dock clerk through three empty corridors does not require 180 consecutive Move maneuvers unless somebody at the table has committed a terrible sin.


Fast table script

When somebody attacks, call it in this order:

  1. Maneuver?
  2. Movement?
  3. Target and hit location?
  4. Attack mode and special options?
  5. Effective skill after modifiers?
  6. Attack roll.
  7. Defense choice and modifiers.
  8. Defense roll.
  9. Basic damage.
  10. 1/2D or other pre-DR changes.
  11. Effective DR and armor divisor.
  12. Penetrating damage.
  13. Wounding and hit-location multiplier.
  14. Final injury.
  15. Shock, major wound, stun, crippling, knockback, consciousness, or death checks.
  16. Ammo, FP, posture, readiness, and continuing effects.

Then call the next name in the order.


Rules intentionally not added here

This guide does not introduce:

  • Committed Attack.
  • Defensive Attack.
  • Telegraphic Attack.
  • Expanded Rapid Strike.
  • Technical Grappling.
  • New hit locations.
  • Custom critical tables.
  • Alternate initiative.
  • Action points.
  • Any Khesret-specific damage bonus.

Those are optional expansions, later-book rules, or house rules. If we use one, it should be named explicitly rather than smuggled into an ordinary Attack maneuver wearing a fake mustache.
