Hexmaster Solo

Hexmaster Solo

A Complete Solo Engine for HexmasterCampaigns

What if your fantasy world kept moving when you weren’t looking? What if dungeons shifted, factions schemed, weather changed, and NPCs remembered—all without a GM?

Hexmaster Solo is a fully featured solo ruleset designed to make d20-compatible play feel alive, reactive, and dangerous. It replaces passive oracles with active systems: clocks, pressure mechanics, environmental modeling, emergent threat cycles, and world-scale simulation.

This is not just “yes/no” solo play. This is a living campaign engine.

FEATURED SYSTEMS INCLUDED

Wilderness Exploration Engine

Hex-based travel with weather modeling, hex hazards, travel modes, supply tension, predator behavior, faction patrols, magical weather, and the Wilderness Pressure Clock—a system that escalates danger the longer you roam.

Dungeon Exploration Engine

Turn-based delving with 10-minute exploration rounds, dynamic room states, trap logic, patrol cycles, arcane surges, denizen migration, rival adventurers, environmental shifts, faction agendas, and a Dungeon Metabolism Clock that ensures dungeons evolve over time.

Robust Social Encounter System

Social interactions are structured encounters with:

• Trust, Suspicion, and Patience clocks
• NPC Disposition, Motive, and Resolve
• Degrees of success that shape negotiation, interrogation, diplomacy, or deception
• Long-term Relationship & Memory Clocks

Run court intrigue, tense negotiations, or interrogation scenes solo and seamlessly.

Combat AI and Dynamic Battlefields

Enemies act with purpose using behavior profiles, morale thresholds, reaction logic, and battlefield escalation:

• Environmental shifts
• Reinforcements
• Hostage/objective changes
• Magical anomalies
• Foe or PC advantage events

Combat becomes cinematic, unpredictable, and narratively charged.

Full World Simulation Loop

Between sessions, the world breathes:

• Faction clocks and schemes advance
• Ecosystems shift
• Prices and scarcity change
• Rumors propagate
• Weather cycles evolve
• Macro-events shape nations and regions

Your world is no longer static—it’s in motion.

THE HEXMASTER ORACLE

A multi-layered oracle suite for inspiration and resolution:

• Yes/No logic with probability bands
• Exceptional results: twists, complications, extremities
• Detail generation across sensory, thematic, and magical categories
• Motivations, reactions, secrets, and scene hooks
• NPC behavioral logic
• Twist engines that reshape story direction

Use it alone or combined with Hexmaster’s simulation clocks for rich emergent storytelling.

HEXMASTER CLASSES

Ten new classes designed specifically for simulationist play:

• Trail Warden & Horizon Witch — masters of weather, hex hazards, and wilderness pressure
• Delver-Savant & Echo Binder — dungeon analysts and whisperers who treat dungeons as entities
• Masked Envoy & Whisper Spider — social manipulators who bend conversations and factions
• Battle Orchestrator & Avalanche Berserker — warriors who shape (or thrive in) chaotic battlefields
• Fate-Touched Seer & Clockwright — oracles and temporal manipulators who influence fate and world clocks

These aren’t generic subclasses—they are mechanically entwined with the solo engine.

WHO IS HEXMASTER FOR?

Solo Adventurers Run full campaigns alone—sandbox, hex-crawl, megadungeon, intrigue, or open world.

GM-Less Groups Play cooperatively with no GM, letting the system drive discovery and danger.

Worldbuilders & Designers Use the simulation engines to generate factions, events, ecology, and evolving political landscapes.

d20 Players Who Want a Living World Plug Hexmaster’s subsystems into a traditional campaign to make your world dynamic and reactive.
