🌟 Genshin Impact Team Optimizer — Luna IV Version 0.2 Beta

A Python-based team rotation optimizer for Genshin Impact that helps players build the best 4-character team based on elements, roles, weapons, and elemental reactions — all powered by a structured Excel database. Built for players who want logic-backed team building, not just vibes.

🎮 What Is This? This tool analyzes your available characters and finds the optimal team rotation by maximizing elemental reaction multipliers, while respecting team composition rules such as:

• Main DPS
• Sub DPS
• Healer / Shield
• Weapon & Element constraints It is designed to be:
• Beginner-friendly 👶
• Flexible for late-game players ⚔️
• Understandable for developers 👨‍💻👩‍💻

✨ Features (v0.2 Beta)

✅ Inventory input using nicknames

✅ Weapon filtering (Sword, Claymore, Bow, Catalyst, Polearm)

✅ Element exclusion filter

✅ Role-based team validation

✅ Build choice selection

✅ Best team rotation order (1 → 4)

2. Ask user for owned characters
3. Apply weapon filters
4. Apply element exclusion
5. (Optional) Enforce role rules
6. Resolve dual-role characters (build choice)
7. Generate all valid 4-character teams
8. Test all possible rotations
9. Pick the team with the highest reaction multiplier score 📌 A detailed flowchart is included in this repository for reference.
