Target first
Party size adjusts the party level, then difficulty establishes a visible target EL. The roster is assembled and its actual EL is calculated independently.
Dungeons & Dragons 3.5
Encounter Generator
Build a reproducible encounter with compatible enemies, an actionable setup, grounded tactics, complete stat blocks, and optional loot.
Balance note: Treat this as a generator heuristic, not a guarantee of balance. Review unusual parties and high-variance monster abilities before play.
Step 2
Your encounter
Ready
The battlefield is quiet
Choose the party and scene constraints, then generate a table-ready encounter.

Have an idea for these generators?
The existing rules and curated datasets will keep growing in future iterations. Suggestions are welcome, including names, descriptions, new entries or features, and changes to existing data or functionality.
How the encounter is built
Coherent ingredients
Structured environments, creature types, and curated tags narrow the local SRD catalog. Premises explain why mixed groups cooperate.
Reusable interfaces
The server-side generator returns structured encounter, roster, setup, tactics, stat-block, and reward data for future quest and dungeon integrations.
Turn a roster into a memorable fight
Use the handbooks on making combat interesting and action economy to refine terrain, pressure, enemy decisions, and the balance between one powerful foe and several weaker enemies.
