ODDS RPG uses:

• 1d20 for resolution
• 2d10 for impact

The system is modular and genre-neutral.

When attempting something risky:

1d20 + Attribute + Skill

Compare to a Target Number (TN).

If you meet or exceed the TN, you succeed.

Beat TN by 5 → Strong Success Beat TN by 10 → Critical Success

Natural 20 → Automatic Strong Success Natural 1 → Failure + Complication

Strong Success should:

• Increase effect
• Reduce time
• Avoid collateral cost

Critical Success:

• Dramatic advantage
• Bonus damage (+5)
• Narrative control moment

All characters have four attributes:

Attribute range:

1. 1 to +5 (Tier dependent)

Starting array:

+2, +2, +1, +0

Skills represent training or specialization.

Skill range:

0 to +5

Typical skill examples: Combat, Shooting, Stealth, Survival, Investigation, Medicine, Arcana, Hacking, Engineering, Persuasion, Streetwise, Piloting

The GM may allow custom skills.

When an action causes measurable effect:

Roll 2d10 + relevant modifier

Used for:

• Damage
• Healing
• Mental strain
• Structural damage
• Influence shifts

Armor reduces incoming damage.

Health = 10 + Might Resolve = 10 + Presence

At 0 Health:

Incapacitated

At 0 Resolve:

Broken (panic, surrender, shutdown)

Conditions impose penalties but do not stack twice.

Shaken:

1. 2 to next roll

Wounded:

1. 2 to physical rolls

Frightened:

1. 2 to mental rolls

Restrained:

Cannot move freely

When circumstances strongly favor you:

Roll 2d20 and take the higher.

Disadvantage: Roll 2d20 and take the lower.

Roll:

1d20 + Agility

Highest acts first.

Short Rest (once per scene):

Recover 1d20 Health OR 1d10 Resolve

Fully recover Health & Resolve

Used for hacking, rituals, repairs, negotiations.

Set a Progress Goal (3–10 successes).

Each successful roll = 1 progress Strong Success = 2 progress

Failure may:

• Add time
• Increase TN
• Trigger encounter
