ODDS RPG supports long campaigns by using Tiers.

A Tier is a campaign dial:

• Tier 1: Gritty
• Tier 2: Heroic
• Tier 3: Epic

You can run a whole campaign at one Tier, or advance across them.

Tone:

Survival, danger, limited resources.

Guidelines:

• Attribute cap: +3
• Armor caps at 2 (rarely 3)
• Healing is slower
• Bosses are rare

Damage:

2d10 (no bonus) OR 2d10 + Attribute (choose one style)

Best for:

westerns, noir, horror, grounded sci-fi

Tone:

Action-adventure, competent heroes.

Guidelines:

• Attribute cap: +4
• Talents are active
• Armor 1–4 exists
• Bosses use phases

Damage:

2d10 + Attribute

Best for:

fantasy, pulp, space opera, cyberpunk

Tone:

• Enemies scale by role + tier
• Bosses have 2–3 phases minimum

Damage:

2d10 + Attribute + Tier (Tier adds +3 at Tier 3)

Boss rule:

Bosses act twice per round OR gain legendary reactions (GM choice).
