Core Game Concepts
The Storytelling System
Yggdrasil uses a dice pool system where you roll multiple d10s and count successes: - Target Number: 8, 9, or 10 on a d10 (or 5, 6 on a d6) - Success: Meeting or exceeding the target number - Failure: Rolling below the target number - Exceptional Success: Getting 5+ successes (or 3+ with Inspiration)
Key Terminology
Dice Pool: The number of dice you roll for an action - Made up of: Attribute + Skill + Modifiers - Example: Intelligence 3 + Investigation 2 + Equipment +1 = 6 dice
Attributes: Your character's basic capabilities
- Physical: Strength, Dexterity, Stamina
- Mental: Intelligence, Wits, Resolve
- Social: Presence, Manipulation, Composure
Skills: Your character's learned abilities - Physical: Athletics, Brawl, Drive, Firearms, etc. - Mental: Academics, Computer, Investigation, etc. - Social: Animal Ken, Empathy, Intimidation, etc.
Merits: Special advantages and abilities your character has Conditions: Temporary states affecting your character Tilts: Environmental factors affecting everyone
The Action Economy
Turn Structure: 1. Initiative: Determine action order 2. Actions: Each character takes one action 3. Resolution: Apply results
Action Types: - Instant Actions: Most common, happen immediately - Extended Actions: Take multiple turns to complete - Contested Actions: Opposing characters roll against each other - Reflexive Actions: Happen automatically or in response
Health and Damage
Health Track: Based on Size + Stamina
- Bashing Damage: Temporary (/)
- Lethal Damage: Serious (X)
- Aggravated Damage: Magical/supernatural (*)
Willpower: Mental resilience (Resolve + Composure) - Spend to add +3 dice to important rolls - Regained through fulfilling Vice or exceptional Virtue
