Trait Tiers
Every offered trait rolls a tier that multiplies its strength. The odds below are for the Nasal Passage; every organ deeper raises the odds of every tier above Common, and from the Liver on, offers are never Common. The Mutagenic Pool's boosted roll is never Common either. Your virus's milestones cap the tier: Rare at first, Epic from Level 7, and up to Prismatic from Level 11 with 4 generations.
