#GM Tools

Master reference material for combat design, session assembly, and campaign operation.

#Guides to Read First

1. GM Starting Guide — Where to Start Reading
2. GM Assembly Guide — Making One Session
3. GM Campaign Guide — Long-Term Operation and Expansion

We recommend reading these three documents in order. If this is your first time as GM, it is faster to read the three documents above before the materials below.

#Rules and Design Reference

• Encounter Design — combat difficulty adjustment, unit composition, zone setup
• Balance Reference Points — the anchor for numeric design. Hit rate/DPT/Wounds/Energy/gold standards
• Yoma Bestiary — yoma stat blocks and examples
• Zone Modification — details of the GM's battlefield modification authority
• OSR Conversion — converting B/X data into Konsei Reiyotan
• Detailed Economy — deeper handling of prices, wages, and trade
