Rarity Calculation

The rarity score is calculated using a statistical approach:

1. Individual Trait Rarity:

   trait rarity = (number of heroes with trait ÷ total heroes) × 100
   

2. Overall Hero Rarity:

   • Multiply all trait rarities together
   • Take the geometric mean (nth root where n is the number of traits)
   • Lower scores indicate rarer heroes
