Refinement Mini-Game Implementation Plan

This document outlines the design and implementation details of the 'Refinement' (재련) mini-game system for Kord.

Overview

The Refinement mini-game allows users to strengthen their virtual weapons, participate in simple battles, and earn gold. It features a high-risk, high-reward progression system with a community-wide 'Fever Time' bonus.

Core Features

1. Weapon Refinement

• Progression: Level- 재련 비용: floor(10 × 1.6^level)G (레벨별 기하급수적 증가)
• 판매 가격: floor(현재_단계_비용 × 2)G
• 재련 성공 확률:
  • 0→4강: 100% ~ 90%
  • 4→5강: 5% (급락)
  • 5→10강: 4% ~ 1%
  • 11→20강: 0.1% (신화)
  • 21→25강: 0.01% (기적)
• 전투 보상: (패배자_단계_비용 × (패배자_레벨/승리자_레벨) × 2.0) × (0.8~1.2 랜덤)
• 최대 단계: 25강 (Lvl 25)
• 전투 규칙:
  • 0강 무기 소유자는 전투를 걸 수 없으며, 공격 대상으로 지정될 수도 없습니다.
  • 전투 참여 시(공격/방어 모두) 내구도 -1.
• 파괴 조건:
  • 재련 실패 시 낮은 확률로 파괴 (0단계 회귀).
  • 내구도가 0인 상태에서 전투 시도(공격) 시 전투 후 무기 파괴. as the level increases.
• Risk: Failure at higher levels can lead to weapon destruction (reset to level 0).
• Durability: Each battle reduces durability. Success and Level Up fully restores durability.

2. Battle System

• One-way Attack: Users can attack others without a formal acceptance process.
• Outcome: Calculated based on weapon levels.
• Rewards: The winner receives gold based on both participants' levels.
• Weapon Destruction: If a user attacks while their durability is 0, their weapon is permanently destroyed.

3. Fever System

• Dynamic Analysis: The bot tracks server message activity per hour.
• Activation: Fever mode activates during the server's peak activity hour (determined by historical data).
• Bonus: +10% success rate for all refinement attempts during Fever Time.

4. Economy & Management

• Gold Sources: Daily check-ins, winning battles, and selling weapons.
• Check-in: /refine checkin grants a set amount of gold once per day.
• Selling: Max level weapons must be sold to restart the progression.
• Registry: Server admins can enable/disable mini-games and restrict them to specific channels via /minigame.

Technical Architecture

• Prisma: Persists user profiles, server configs, activity logs, and fever states.
• ActivityTrackerService: Buffers and saves message counts to avoid DB bottleneck.
• FeverService: Analyzes activity and manages the 1-hour fever window.
• RefinementService: Contains the core game logic (probabilities, rewards).

Implementation Progress

• Database Schema updates
• Infrastructure (Registry, Activity Tracking)
• Game Logic (Refinement, Battle, Economy)
