Black Trigram (흑괘) - Damage System Overview

This document provides a quick-reference overview of the Black Trigram damage calculation for TypeScript implementations.

Quick Reference

Damage Formula: Final=max(1,(Base×Archetype×Stance×Anatomy×Critical)×(1−DefenseReduction))\text{Final} = \text{max}(1, (\text{Base} \times \text{Archetype} \times \text{Stance} \times \text{Anatomy} \times \text{Critical}) \times (1 - \text{DefenseReduction}))

Multipliers:

  • Archetype: 0.9x-1.5x
  • Stance: 0.8x-1.5x
  • Anatomy: 1.0x-2.0x
  • Critical: 1.0x or 2.0x
  • Defense Reduction: 0-0.8x (max 80% reduction, defender defense / 200)

Minimum Damage: Always deals at least 1 HP damage

Note: This is a simplified overview. The canonical implementation of damage, including exact defense reduction and minimum damage floor logic, is in src/systems/vitalpoint/DamageCalculator.ts (see lines 172-177).

See COMBAT_ARCHITECTURE.md for complete vital points system and worked examples.
