#Quick Reference

Everything needed during combat on one page.

Summary. This document is a quick-reference summary of the core rules. If this document conflicts with Canon documents(co-03-04-action-points.md, co-03-09-non-combat.md, co-05-03-breakthrough.md, co-06-06-squads.md), Canon takes precedence. When in doubt, follow the reference link for each item. Authority system: co-99-meta/co-99-01-authority.md.

#Checks

2d10 + ability + proficiency >= Target Number

• General difficulty Target Number: 11 | easy 7 | hard 13 | extreme 17
• Fixed combat values: Defense, Breakthrough/Blockade/Core Zone, Overload, and condition resistance follow the fixed values in each rule.
• Attack: 2d10 + ability + proficiency >= Defense (the ability differs by technique!)

#Doubles (10%)

• Success + double = Critical Hit (usually 2 Wounds)
• Failure + double = Fumble (Defenseless)
• 10-10 = Heavenly Mandate / 1-1 = Karmic Retribution (see d100)

#Fate Intervention

After 2d10, adjust one d10 by ±1. Uses per combat equal Fate modifier, minimum 1 use. Post-combat life-or-death checks are 2d10 + the higher of Physique or Fate >= 11.

#Round Structure

all Energy maximum → count descending → one breath(default 5) → alternate with enemies → everyone 0 → lull

#Count Progression

1. Round start: reset everyone's Energy to maximum.
2. Start from the combatant with the highest remaining Energy, descending. Anyone at or above that count breathes.
3. Ties: Finesse(技) descending → allies first.
4. After a breath, Energy decreases → next count = highest remaining value.
5. A character can breathe multiple times inside a round (as long as Energy remains).

#One Breath

• Base limit: Energy 5. Can be expanded by Fast Resolution, Speed, and special effects.
• Exceeding the limit = Overload: 2d10+Physique-excess >= 11.
• Success: performed; immediately after, 1 breath limit becomes 3.
• Failure: performed; all remaining Energy in the round is lost + Defenseless.
• Reservation: prepay defensive technique → 0 when executed. Improvised → 1.5 times.

#Maneuver Types

#Defense Bypass and Pierce Tags

Defense-bypass effects are written in the 3 families [Pierce], [Direct], and [Incorporeal]. Defense -N is a debuff. [Break] is a supplementary equipment-damage effect that keeps the listed [Pierce N] reduction until repair. Details: co-03-05 §Defense/Pierce System.

Keep check formulas in the single >= Defense form; write tags in the effect area: 2d10+Finesse+Swordsmanship >= Defense | [Pierce 2]. 1 Wound.

#Weapon Technique Slots

#Common Maneuver Costs

#Unit Wounds

#Zone Maneuver Modifiers

Front Zone↔Front Zone: adjacent. Range:adjacent techniques can engage without Breakthrough.

#Domination Contribution

Core Zone special: all Domination bonuses are invalid. Both sides offset(allies-enemies).

#Armor

#Ranged Weapon Basic Range (General Techniques)

• School expansion: Kan-ryu Spearmanship 2 zones, Nanban-ryu teppo 3 zones, Ogasawara Archery secret art unlimited, etc. See School Quick Reference.
• Masterwork expansion: One Shot, One Kill, long-range sniping, etc. have unlimited range. See Masterworks Compendium.

#Intangible / [Incorporeal]

• Intangible yoma: on physical attack hit, d100 01~50 negates. Exorcism beginner(1 point)+ exempts.
• [Incorporeal] attack: bypasses Defense itself. Defender applies the Exorcism tier exemption table.
• Armor/barrier bypass notation uses the above Defense Bypass and Pierce Tags standard.

#One-Breath Limit Changes (baseline cap 7, no absolute cap)

Different sources stack. Official balance uses 7 as the baseline cap, but the system has no absolute cap. The Overload threshold also changes to match the actual limit.

#School Quick Reference

#Noncombat Check Quick Reference

#Squad Command Cost

#Bonus Stacking Rules

• Effects with the same name: do not stack (highest only).
• Numeric bonuses from different sources: add together.
• Stance + Tactic:Stance: separate (can be maintained together).

#Energy Cost Handling (4 Rules)

1. Absolute floor: every maneuver costs at least 1 Energy. 0 Energy only for explicit exceptions.
2. Offset first: calculate base cost + penalty - bonus first; if lower than 1, raise to 1 Energy.
3. Short weapons in Core Zone: a 1 Energy weapon converts Energy -1 → chain-attack fatigue -1.
4. 0 Energy active: automatically gains a [1/round] limit. Maximum 2 uses per round.

Exceptions: scholar Energy transfer(received Energy = ordinary Energy), dropping a stance, permanent [Aptitude], reserved defense activation.

#Fraction Handling

Round all values. No exceptions.

#Surprise Attack (奇襲)

• Basic Surprise Attack (Flank Zone→adjacent move+attack, first infiltration hit): first attack check +2
• Enhanced Surprise Attack (Outside Zone→anywhere): first attack check +2 + target cannot use reaction techniques
• Shinobi [Surprise Attack] 3rd dan trait: true automatic Critical Hit (no check). No added Defenseless
• Weapon license/masterwork techniques and school license/secret arts can also apply Surprise Attack (regardless of maneuver type)
• Surprise Attack immunity: [Danger Sense] trait, Perception Master

#Squad Volley Fire — Scales by Hit Strength

#Breakthrough / Forced Charge / Pincer

• Breakthrough: enter a zone where enemy Domination is superior. 3 Energy + 2d10+Courage ≥ 12.
• Chain breakthrough: entering the Rear Zone is not a separate rule. The Target Number is the higher of Front Zone Domination and Rear Zone Domination.
• Forced Charge [Kata]: 5 Energy. Go straight to the enemy Rear Zone in one breath. Target number = Front Zone+Rear Zone Domination+5. On failure, Defenseless in the middle of the enemy Front Zone + Energy 0 + next round Energy −3 (exhaustion). Details: co-05-03-breakthrough.md.
• Pincer: both sides adjacent + both sides attack simultaneously. Enemy Defense -2, Cohesion check -1.

#Pull Into Core Zone [Kata]

• 3 Energy. 2d10+Physique+Unarmed Combat ≥ 12+target Domination contribution.
• Reserved defense triggers first (2-layer check).
• Success: forcibly move target into Core Zone + drop stance + Defenseless.

#Core Zone Control Rewards

• Control for 1 round: allied Front Zone Domination +1 (while maintained). Cohesion +1 (1 use).
• 3 consecutive rounds: Core Zone disappears. Enemy Cohesion -3, allied Cohesion +2, next round Critical Expansion(adjacent numbers also critical), 1 enemy Rear Zone squad automatically collapses.

#Leaderless Squad (when commander dies)

• Immediately Cohesion -1. 5-type differential table (regular/defensive/fanatic/conscripted/frenzied).
• Veteran in the same zone can take temporary command.
• Decide table at scenario start → maintained until end.

#4 Support Squad Types

• Supply unit: Cohesion recovery +1/lull. Must be protected.
• Military band: stance that grants immunity to Cohesion -1. Drumbeat gives Cohesion +1.
• Medical unit: returns incapacitated combatants during lull. Emergency treatment.
• Standard-bearer unit: Domination +1 aura. If captured, army Cohesion -2.
• Kagura Domain exception: no standard-bearer unit. Regular military discipline is built in.

#Battle Scaling

• 5-person squad = 1 unit. 100-person force = 1 Minion squad. 5-thousand army = compressed into one point.
• 5 key battle-state types: control key point / kill commander / surprise headquarters / break vanguard / defend key point.

#Trait Slots — Lower Dan Selection Allowed

When advancing in dan, you can select traits from lower dan. A 7th dan can additionally choose the 1st dan trait "Tough."

#Dual-Wielding Separation

• [Aptitude] Dual Wielding: can use two weapons in one breath
• [Kata] Dual-Wield Strike: Energy = combined Attack A of two weapons (example: katana 2+kodachi 1=3). Simultaneous two-hand strike. 1/round.
