"매 Type-Moon Fate franchise 의 core conflict — 매 7 master + 7 servant 의 Holy Grail 의 의 의 battle royale". Fate/stay night (2004) 시작 — 매 Visual Novel + 매 anime + 매 Fate/Grand Order (gacha) 등 expand. 매 narrative AI / 매 game design 의 reference.

5. Visual novel: 매 branching.

💻 패턴 (응용)

Class triangle

CLASS_ADVANTAGE = {
    'Saber': ['Lancer'],
    'Lancer': ['Archer'],
    'Archer': ['Saber'],
    'Rider': ['Caster'],
    'Caster': ['Assassin'],
    'Assassin': ['Rider'],
    'Berserker': [],  # 매 매 class 의 advantage but takes 2x damage
}

def damage_modifier(attacker_class, defender_class):
    if defender_class in CLASS_ADVANTAGE.get(attacker_class, []): return 1.5
    if attacker_class in CLASS_ADVANTAGE.get(defender_class, []): return 0.5
    if attacker_class == 'Berserker': return 1.5  # 매 매 매 class
    return 1.0

Servant data

@dataclass
class Servant:
    true_name: str
    class_: str
    skills: list[str]
    noble_phantasm: dict
    parameters: dict  # 매 STR/END/AGI/MAG/LCK/NP — 매 E~A++
    alignment: str

Noble Phantasm trigger

def noble_phantasm(servant, master_mp, charge):
    if charge < servant.np.threshold:
        return 'insufficient_charge'
    if not master_mp.has(servant.np.cost):
        return 'mp_drain_master'
    return execute(servant.np)

Command Spell (3-use)

class Master:
    def __init__(self):
        self.command_spells = 3
    
    def use_command_spell(self, command):
        if self.command_spells == 0: raise NoSpellsError()
        self.command_spells -= 1
        # 매 absolute order 의 servant 의 force
        # 매 1: location-jump, 2: instant-restore, 3: kill-self-NP
        return self.servant.execute_absolute(command)

Battle royale logic

def grail_war_round(masters):
    alive = [m for m in masters if m.alive and m.servant.alive]
    if len(alive) <= 1: return alive[0] if alive else None
    
    # 매 territorial expansion + alliances
    encounters = pair_encounters(alive)
    for m1, m2 in encounters:
        outcome = simulate_combat(m1, m2)
        if outcome == 'm1_win': m2.alive = False
        elif outcome == 'm2_win': m1.alive = False
        else: break_alliance(m1, m2)

Visual novel branching (Ren'Py-like)

label crossroads:
    "Saber waits for orders."
    menu:
        "Engage Lancer":
            jump engage_lancer
        "Retreat":
            jump retreat_route
        "Attempt alliance":
            jump alliance_route

Gacha rarity (Fate/GO-style)

RARITY_RATES = {1: 0.40, 2: 0.30, 3: 0.20, 4: 0.07, 5: 0.03}

def gacha_pull(rates=RARITY_RATES):
    r = random.random(); cum = 0
    for rarity, rate in sorted(rates.items()):
        cum += rate
        if r <= cum: return draw_servant(rarity)

Heroic spirit lore (LLM-aided)

def generate_servant(historical_figure, class_):
    prompt = f"""Design a Fate-style servant.

Historical figure: {historical_figure}
Class: {class_}

Output JSON:
- true_name
- class
- 3 skills (with grade)
- noble_phantasm (name, type, effect, rank)
- parameters (STR/END/AGI/MAG/LCK)
- one-line summary"""
    return llm.generate(prompt)

매 결정 기준 (응용)

상황	Approach
Battle royale game	매 alliances + 매 reduction
Class system	Triangle
Mobile gacha	Tiered rarity + pity
Narrative game	VN branching
LLM character	Heroic spirit gen

기본값: 매 lore-rich character + 매 class triangle + 매 multi-route narrative + 매 (mobile) gacha pity.
